If you're looking for Vapi AI alternatives, whether because of pricing, missing features, or just wanting to explore what else is out there, this list covers ten solid options worth considering.
It starts with Zeeg, Europe's leading AI phone assistant and appointment scheduling software in one solution — GDPR-compliant, made in Germany — and works through nine other tools for different use cases and technical skill levels.
The timing is worth noting. According to Okta's 2026 Businesses at Work report, 91% of organisations say they are already using AI agents, but only 10% report having a well-developed strategy for managing them.²¹ Choosing a platform that fits how your business actually runs is most of that strategy.

What are the 10 best alternatives to Vapi AI in 2026?
A Vapi AI alternative is any platform that lets you build and run AI voice agents that handle real phone calls. The ten below differ mainly in two things: how much engineering work they expect from you, and whether appointment booking is built in or has to be bolted on afterwards.
1. Zeeg — Best vapi AI alternative for booking-focused voice AI
Zeeg isn't just a voice AI tool. It's a scheduling CRM with a natively built voice AI agent, which is what makes it different from most alternatives to Vapi AI. Instead of connecting a separate voice layer to a booking tool via third-party integrations, everything is in one place: the AI agent answers calls, qualifies leads, and books meetings directly into your CRM.
Where the agent is built and hosted also matters more than it used to. In a representative Bitkom survey of 604 German companies with 20 or more employees, 93% said they would prefer an AI provider based in Germany.²² For any team putting an AI agent on the phone with customers under GDPR, that preference tends to show up as a procurement requirement rather than a nice-to-have.
Key features
- Handles both inbound and outbound calls with real back-and-forth conversation (not a phone tree)
- Automatically gathers caller details — name, email, company type — during the call
- Smart routing rules written in plain language: define what happens based on caller intent
- Full call transcripts with timestamps and AI reasoning, stored in the CRM
- Buy a local phone number directly in Zeeg, or import your existing number via SIP
- Built-in test panel so you can call your agent before publishing
- Pre-built agent templates: Appointment Booker, Sales Qualifier, Support Callback
- Supports multiple workspaces and multi-team routing scenarios
Pricing
Zeeg prices its two products separately. Scheduling is per seat and starts on the Professional plan at €10/user/month billed annually, or €12/user/month billed monthly — and the AI voice agent can be bought on its own, even on the free Starter scheduling plan. Voice minutes are sold as monthly packages, and every package includes the full feature set, so the only thing that changes between them is the minute allowance and your effective cost per minute. Outbound calls are agent-initiated and carry a higher rate than inbound.
In effective per-minute terms, inbound runs from about €0.24/min on Starter down to €0.13/min on Enterprise at monthly billing, or about €0.20 down to €0.11 with annual billing. Outbound runs from roughly €0.33 to €0.19 monthly, or €0.27 to €0.16 annually. There's also a free Starter scheduling plan, a 14-day trial on paid scheduling plans, and 5 free AI voice minutes on every new account.
What do users say?¹
Users praise how fast the setup is with no coding required, and the prompt-based agent makes it accessible even for non-technical teams. The native CRM logging and transparent per-call costs are often called out as standout features compared to other tools that require stitching together multiple platforms.
Verdict
If your main goal is automating phone-based lead capture and meeting booking (without the overhead of integrating separate tools) Zeeg is the most complete option on this list. It's especially well-suited for small businesses, sales teams, and anyone who's been missing calls and losing leads because of it.
Zeeg's AI agent picks up every call, captures lead details, and books the meeting — all without you lifting a finger. 14-day free trial, no credit card required.

Moving on from Zeeg, Retell AI is a developer-focused voice AI platform that lets you build, test, and deploy conversational AI agents. It's a close alternative to Vapi AI in terms of the audience it targets: teams that want programmatic control over call flows and agent behavior.
Key features
- Build voice agents using LLM prompts or custom function calling
- Inbound and outbound call support
- Real-time call transcription and analytics
- Webhook and API-based integrations
- Multi-language support
- Testing environment before deployment
Pricing²
Retell AI is usage-based with no platform fee, and publishes a range of $0.07–$0.31 per minute on its pay-as-you-go plan. The reason the range is that wide is that you compose the price yourself: Retell's voice infrastructure is $0.055/min, text-to-speech is $0.015/min on standard voices (ElevenLabs is $0.040/min), the LLM runs anywhere from $0.003/min for the smallest models to $0.16/min for the largest, and telephony is $0.015/min through Retell or free on your own SIP trunk. New accounts get $10 in credits and 20 free concurrent calls; extra concurrency is $8/month per call. Enterprise pricing is custom.
What do users say?³
Developers appreciate the flexibility and how close Retell AI sits to the underlying infrastructure. That said, non-technical users often find the setup steep, and some note that getting a polished, reliable agent running requires more effort than expected.
Verdict
A solid Vapi AI alternative if your team is technical and wants fine-grained control. Less ideal if you're looking for something that works out of the box — and worth modelling your actual model and voice choices before budgeting, because the top of the published range is more than four times the bottom.
3. Bland AI — Built for high-volume outbound calling
Moving more toward the sales and outreach side of things, Bland AI focuses on high-volume outbound voice calls. It's designed for teams running large-scale phone campaigns like follow-ups, appointment reminders, and lead outreach at scale.
Key features
- Conversational AI for outbound call campaigns
- Real-time call scripting and dynamic variable injection
- Human handoff when the AI can't handle a query
- Call analytics and recording
- CRM integrations via API
- Simple no-code pathway builder for call flows
Pricing⁴
Bland moved off a single flat rate at the end of 2025, and per-minute pricing is now tied to your plan tier. The free Start plan bills connected minutes at $0.14/min with transfers at $0.05/min. Build is $299/month and drops connected minutes to $0.12/min and transfers to $0.04/min. Scale is $499/month at $0.11/min and $0.03/min. Enterprise is custom. Note that the widely quoted $0.09/min figure is the old universal rate, which no longer applies.
What do users say?⁵
Users running outbound campaigns tend to like Bland AI's scalability and the human handoff feature. Some note that the conversational quality can feel scripted in complex scenarios, and integration depth outside the API isn't always that straightforward.
Verdict
A reasonable alternative to Vapi AI for outbound-heavy use cases, and the tiered structure means the monthly fee only pays for itself at real volume — Build breaks even against Start somewhere around 15,000 minutes a month. If your priority is inbound booking and CRM logging, though, it's not the most natural fit.
4. Synthflow — No-code voice AI for enterprise teams
Synthflow is the no-code option in the voice AI space, a platform where you can build phone agents through a visual interface without writing a single line of code. That alone separates it from Vapi and many developer-first alternatives — but it is worth knowing up front that Synthflow has moved decisively upmarket, and no longer sells a self-serve plan.
Key features
- Drag-and-drop agent builder with no coding required
- Inbound and outbound call handling
- CRM integrations (HubSpot, GoHighLevel, and others)
- Real-time booking via calendar integration
- Multi-language support
- White-labeling for agencies
- Native telephony, SIP trunking, and custom concurrency planning on enterprise contracts
Pricing⁶
Synthflow now publishes enterprise pricing only. Its pricing page states that enterprise contracts start at $30,000 annually, with final pricing scoped around call volume, concurrency, telephony setup, integrations, security requirements and launch support. The free plan and the low monthly tiers that Synthflow offered previously are no longer listed, so any figure you see quoting a $29/month starting price is out of date.
What do users say?⁷
The no-code builder gets positive marks from non-technical users and agencies. On the flip side, some users report that the agent quality can be inconsistent on complex conversations, and the pricing scales up quickly once you need more call minutes.
Verdict
Synthflow is a credible Vapi AI alternative if you are an enterprise buying a no-code platform with a scoped implementation behind it. It is no longer an option for a small team that wants to try something without a contract — at a $30,000 annual floor, it is not competing for the same buyer as most of this list.
5. Goodcall — Simple AI receptionist for small service businesses
On the more accessible end of the spectrum, Goodcall takes a different angle: instead of giving you infrastructure or a dev-first platform, it's built to act as a virtual front desk for small local businesses. Think salons, HVAC companies, clinics, and any operation that gets the same inbound questions dozens of times a day.
Key features
- Answers inbound calls and handles FAQs automatically
- Appointment scheduling with calendar sync
- Pulls business info directly from your Google Business Profile for fast setup
- Conditional logic flows for call routing
- CRM and Zapier integrations
- Unlimited call minutes on all plans (billed by unique callers per month, not by the minute)
- Team performance dashboard with call recordings and analytics
Pricing⁸
Goodcall charges per agent per month based on unique customer interactions, not call duration, which is unusual in this space. Plans start at $79/month (Starter, up to 100 unique customers), $129/month (Growth, 250 customers), and $249/month (Scale, 500 customers). Annual billing reduces those to roughly $66, $108 and $208. Extra unique customers beyond the plan limit are charged at $0.50 each.
What do users say?⁹
Setup speed gets consistent praise. Goodcall states that connecting your Google Business Profile produces a working agent in under 30 minutes,⁸ and reviewers broadly bear that out — a genuine differentiator for non-technical owners. Where users hit limits is on nuance: complex conversations or edge cases can trip it up, and there's no sandbox for testing changes before they go live. Some also flag that the voice quality, while clear, lacks the natural feel of newer platforms.
Verdict
Goodcall works well as a Vapi AI alternative for simple inbound scenarios: answering calls, booking appointments, handling common questions. If you need more complex routing logic, developer access, or production-grade conversation quality, it'll feel limiting fairly quickly.
6. Voiceflow — For teams building complex voice experiences
Voiceflow is more of a voice application design platform than a simple call agent tool. If you want to build sophisticated, multi-step conversational experiences (across phone, IVR, and even voice assistants) it gives you the tools to do that.
Key features
- Visual conversation designer with branching logic
- Multi-channel support: phone, web chat, voice assistants
- API and webhook integrations
- Team collaboration features
- Prototype and testing tools
- Enterprise security and compliance options
Pricing¹⁰
Voiceflow is priced per editor seat rather than per minute. There's a free Starter tier for individuals, then Pro at $60/editor/month and Business at $150/editor/month, with Enterprise on request. Each paid plan comes with a fixed monthly credit allowance that testing and production both draw from, and annual billing takes roughly 10% off. The per-seat model is the thing to watch: a three-person team on Pro is $180/month before any usage.
What do users say?¹¹
Design and product teams tend to like Voiceflow for its visual builder and collaboration features. The learning curve is steeper than simpler tools, and for simpler phone booking scenarios, it can feel over-engineered.
Verdict
A strong Vapi AI alternative if you're building complicated voice flows or working with a product team. Probably too much for businesses that just need to answer calls and book meetings automatically.
7. Livekit Agents — Open-source infrastructure for voice AI
For teams that want complete control and are comfortable with infrastructure-level work, LiveKit Agents is worth talking about. It's an open-source framework for building real-time voice AI applications. It’s a lower level than Vapi, but with maximum flexibility.
Key features
- Open-source framework with full code access
- Real-time audio and video pipeline
- Support for multiple LLMs and STT/TTS providers
- WebRTC-based architecture
- Active developer community and documentation
- Self-hostable
Pricing¹²
LiveKit's cloud platform has a free tier and usage-based pricing. For self-hosted deployments, it's free to use (open-source), with infrastructure costs depending on your setup. Note that LiveKit prices the transport and agent runtime only — STT, LLM and TTS are your own separate vendor bills on top, so the headline is not a comparable all-in figure.
What do users say?¹³
Developers who need maximum control and customization are the clearest audience here. It's not a tool you'd hand to a non-technical team as setup requires real engineering effort.
Verdict
A legitimate alternative to Vapi AI at the infrastructure level. Outside of technical teams building custom voice stacks, this isn't a practical day-to-day tool.
8. Thoughtly — Voice AI with built-in analytics
Thoughtly is a newer entrant in the voice AI space as it aims to combine AI phone agents with solid call analytics. The pitch is that you can run both inbound and outbound calls while getting clear visibility into what's actually happening in those conversations.
Key features
- AI-powered inbound and outbound calling
- Built-in call analytics and reporting dashboard
- CRM and calendar integrations
- Human handoff capabilities
- Agent templates for common use cases
- A/B testing for call scripts
Pricing¹⁴
Thoughtly does not publish a public pricing page. Paid plans are quoted through their sales team, so you would need to book a demo to get specific numbers — which also means any per-minute figure you find quoted elsewhere is second-hand and worth confirming directly.
What do users say?¹⁵
Early users mention the analytics dashboard as a genuine differentiator, getting call-level insights is cleaner than in some competing tools. Concerns tend to center around pricing as call volume scales up.
Verdict
A solid option if analytics and call performance visibility are priorities. For small businesses or teams mainly focused on booking, the lack of published pricing makes it hard to evaluate without a sales conversation.
9. Telnyx — Full-stack voice AI on owned infrastructure
Unlike most platforms in this space that sit on top of rented infrastructure, Telnyx owns and operates its own private global network. The company states it runs carrier-grade fiber across a Tier-1 network spanning dozens of countries, with GPUs co-located directly alongside its telephony infrastructure.¹⁶ That architecture is the whole pitch: less latency, fewer third-party handoffs, and more predictable costs.
Key features
- End-to-end voice AI stack: STT, TTS, LLM orchestration, and telephony in one platform
- Sub-200ms latency via private IP backbone (Telnyx's own published figure)
- No-code AI Assistant Builder alongside full API access
- SIP trunking, number provisioning, and porting
- Real-time multilingual transcription across a wide language set
- STIR/SHAKEN, SOC 2, HIPAA, PCI, and GDPR compliant
- Bring your own LLM or use Telnyx-hosted open-source models
- Integrations including Salesforce, HubSpot, and Zendesk
Pricing¹⁶
Telnyx is pay-as-you-go. Voice AI agents are $0.05/min, and that rate bundles orchestration, speech-to-text and Telnyx-native text-to-speech — components most competitors bill separately. LLM tokens are billed on top, per token rather than per minute, whether you use Telnyx's own GPUs or a managed OpenAI or Anthropic model. Telephony is additional at carrier rates. Telnyx estimates a realistic production agent lands near $0.056/min all-in; that figure assumes prompt caching and a moderate token load, so a chatty agent on a large model will cost more.
What do users say?¹⁷
Teams that have switched from Twilio or Vapi often point to the latency improvement and the unified billing as the main wins. Since the telephony and AI layers are the same platform, there's less debugging across vendors. The main caveat is that it's still developer-oriented, so non-technical users will need some setup support.
Verdict
Telnyx is a strong Vapi AI alternative for teams that want production-grade infrastructure without stitching together multiple providers. The latency and network claims above are Telnyx's own, so test them against your actual call volume before committing — and note that it still requires technical resources to get the most out of it.
10. SignalWire — Developer-first telephony with a bundled AI runtime
Rounding out the list, SignalWire is a cloud communications platform built by the team behind FreeSWITCH. It's developer-oriented and offers voice AI capabilities along with standard telephony features, which makes it a viable alternative for technical teams evaluating Vapi AI.
Key features
- AI-powered voice agents via SignalWire AI Gateway (SWAIG)
- Real-time speech recognition and TTS
- SIP trunking and phone number management
- REST API and WebRTC support
- Call analytics and recording
- Built-in agent memory and retrieval
Pricing¹⁸
SignalWire prices its AI Agent Runtime at $0.16/min, and that single rate covers speech-to-text, LLM inference, orchestration and standard text-to-speech — there is no separate token bill. Voice transport is billed on top at telephony rates: $0.0030/min for SIP or WebRTC, $0.0066/min inbound and $0.0080/min outbound on local PSTN numbers, and $0.0147/$0.0069 on toll-free. SignalWire says most customers land at an all-in rate of roughly $0.163–$0.168/min. There are no setup fees and no monthly minimums.
What do users say?¹⁹
Developers with telephony backgrounds tend to find SignalWire highly capable, and the single-invoice model removes the token-accounting problem that comes with assembling your own stack. Non-technical users, however, find the setup process difficult to navigate without help.
Verdict
A technically strong alternative to Vapi AI, and the most predictable pricing on this list — but predictable is not the same as cheap. At $0.16/min for the AI runtime, SignalWire is priced above most of the component-based platforms here once you have tuned them, so it suits teams who would rather pay a known rate than manage four vendor bills.
Which Vapi AI alternative is right for you?
The answer depends a lot on what you actually need. If you're a developer who wants raw control over how your voice agent behaves, Retell AI, LiveKit, or SignalWire are worth exploring. If you're running outbound campaigns at scale, Bland AI makes more sense. And if you want no-code setup for a small non-technical team, Goodcall is the realistic option — Synthflow builds the same kind of thing, but now sells enterprise contracts only.
That said, if the end goal is turning inbound calls into booked meetings (automatically, without manual follow-up) Zeeg does that natively, without requiring you to connect a voice tool to a separate scheduling tool and a separate CRM. Everything is in one place, the per-call costs are transparent, and you can be live in minutes with a prompt and a phone number.
Zeeg's AI agent picks up every call, captures lead details, and books the meeting — all without you lifting a finger. 14-day free trial, no credit card required.
