Buyer's guide · Updated July 2026Best Vapi Alternatives in 2026
Vapi is a capable voice-agent orchestration layer, but its advertised ~$0.05/min platform fee is only part of the bill — STT, LLM, TTS, and telephony are added on top, so real all-in costs often land at $0.13–$0.31 per minute. Here are seven alternatives worth evaluating, from unified platforms to no-code builders.
Third-party rates below are published/advertised figures — always verify against current vendor pricing and model your own usage before deciding.
Why teams look for Vapi alternatives
- Total per-minute cost grows quickly once provider fees stack on the orchestration fee.
- Voice agents are the whole product — meetings, widgets, translation, and team calling need extra vendors.
- Teams without engineers can struggle with an API-first setup path.
The 7 best Vapi alternatives at a glance
| Platform | Best for | Published pricing |
|---|
| MediaSFU | Teams that want voice agents and the rest of the communication stack on one bill | Agent infrastructure $0.002/min; audio transport $0.0001/min; BYOK — AI and SIP provider costs stay direct with no markup. |
| Retell AI | Teams building phone-based support or sales agents with a managed stack | Usage-based; published combined voice-agent rates typically start around $0.07/min. |
| Synthflow | Non-technical teams that want subscription pricing instead of pure usage billing | Plans from around $29/month with bundled minutes; overage rates apply. |
| Bland AI | High-volume outbound calling with a self-serve API | Advertised around $0.09–$0.11 per talk minute depending on plan and bundling. |
| ElevenLabs Agents | Products where voice quality is the primary differentiator | Published additional-call rates around $0.08/min on paid tiers. |
| Telnyx | Teams that want to own telephony at the carrier level | Carrier per-minute rates plus AI usage; competitive at high PSTN volume. |
| LiveKit Agents | Engineering teams that want open-source control and are ready to build | Open source self-host is free; LiveKit Cloud is usage-based. |
Each alternative in detail
#1
MediaSFUOur platform
Unified real-time platform: AI voice agents plus meetings, cloud phone, translation, and widgets
Disclosure: MediaSFU is our platform. We have kept this entry factual and linked published pricing so you can verify every claim.
Strengths- Agent infrastructure at $0.002/min — roughly 25x below Vapi’s published $0.05/min platform rate
- BYOK: pay your STT, LLM, TTS, and SIP providers directly with no markup
- Includes meetings, live translation, click-to-call widgets, recording, transcripts, and 10 SDKs
- No-code paths (Phone Agents Studio, Widget Studio) alongside full API/SDK control
Trade-offs- Smaller community than the largest voice-AI-only platforms
- Broader platform surface means more concepts to explore than a single-purpose tool
#2
Retell AI
Voice-agent platform focused on contact-center style deployments
Strengths- Strong conversation flow tooling
- Batch calling and contact-center features
- Managed provider stack option
Trade-offs- Voice agents only — no meetings, widgets, or broader RTC surface
- Per-minute platform fee scales with volume
#3
Synthflow
No-code AI voice agent builder
Strengths- Genuinely no-code setup
- Predictable subscription pricing at low volume
- Templates for common receptionist flows
Trade-offs- Less flexible for custom pipelines or deep integrations
- Bundled-minute plans get expensive at scale
#4
Bland AI
Developer API for scaled outbound and inbound phone agents
Strengths- Simple API surface for phone agents
- Self-hosted-model story for enterprise
- Fast to prototype outbound flows
Trade-offs- Bundled per-minute rate is among the higher published rates
- Narrow product scope beyond phone calls
#5
ElevenLabs Agents
Conversational agents built around ElevenLabs voices
Strengths- Best-in-class TTS voices

#6
Telnyx
Carrier-grade network with voice AI on top
Strengths- Owns its network — strong call quality and global numbers
- Deep SIP trunking control
- Competitive PSTN rates
Trade-offs- More telecom-shaped than product-shaped; steeper setup

#7
LiveKit Agents
Open-source WebRTC infrastructure with an agents framework
Strengths- Open source, self-hostable
- Flexible Python/Node agents framework
- Strong real-time media foundation
Trade-offs- You assemble the product yourself — telephony, workflows, and UI are your job
- Cloud costs grow with session minutes
When staying with Vapi makes sense
- You want a voice-agent-first developer platform with a large ecosystem of examples.
- Your surrounding communication stack (meetings, telephony operations) already exists elsewhere.
- Per-minute platform fees are acceptable at your volume.
Frequently asked questions
What is the cheapest Vapi alternative?
On published infrastructure rates, MediaSFU is among the lowest at $0.002 per agent minute plus $0.0001 per audio minute, with AI provider costs paid directly (BYOK). Always model your own minute volume, provider mix, and call routes — bundled platforms can be simpler at very low volume.
Why do Vapi bills end up higher than $0.05/minute?
Vapi’s ~$0.05/min covers orchestration only. Speech-to-text, LLM tokens, text-to-speech, and telephony are billed on top, which commonly brings real all-in costs to $0.13–$0.31 per minute depending on the provider mix.
Can I keep my phone numbers and SIP trunks when switching?
Usually yes. Platforms like MediaSFU and Telnyx support bringing your own SIP trunks and numbers; verify routing and regional constraints during a migration test before cutover.
Which alternative is best for non-developers?
Synthflow is the most no-code option. MediaSFU also offers no-code paths (Phone Agents Studio and Widget Studio) while keeping SDK and API depth for when engineers get involved.
Do any alternatives include more than voice agents?
MediaSFU is the broadest: voice agents plus video meetings, live translation, cloud phone, recording, transcripts, and embeddable widgets on one platform. Most other Vapi alternatives are voice-agent-only.
