Let me say the honest thing first: for a lot of teams, Retell is the right answer. It gets a working phone agent live in days rather than months, the speech side is handled for you, and you still get an itemised bill and your pick of the AI model. The voice engine runs about $0.07 a minute ($0.055 for the part that hears and speaks, plus $0.015 for text-to-speech), the AI model is your choice on top (GPT-4.1 is the recommended default at $0.045 a minute), and a realistic all-in lands between $0.13 and $0.31 a minute. If you are not switching for a specific reason, you probably should not switch.
This page is for the people who do have a reason. So it is not a “10 best Retell killers” listicle. It is five alternatives that each beat Retell at one particular job, with an honest note at the end on where Retell still wins. The reason you are leaving decides where you should go, so let me start there.
Why people look past Retell
Four reasons come up again and again. None of them is “Retell is bad”. Each is “Retell is not built for my specific thing”.
- The bundled floor is higher than a tuned build-your-own. Retell’s voice engine is a fixed $0.055 plus $0.015, and you pay GPT-4.1 at $0.045 on top of that. A platform that lets you wire the parts yourself can start lower: Vapi’s own charge is $0.05 a minute to host the call, with speech-to-text, the model and the voice billed at provider cost (no Vapi markup when you bring your own keys), so the floor is lower if you are willing to tune it. You are paying Retell for the convenience of not tuning it. For a lot of buyers that is a fair trade, but if every cent per minute matters at volume, the bundle costs you.
- Only about two languages. Retell lists English and Spanish. If you need to run agents in French, German, Portuguese or further afield, that is a hard limit, not a setting you can change. Vendors like Telnyx (about 29 languages) and ElevenLabs (70-plus) are in a different bracket here.
- No MCP for tool-orchestrated calls. Retell does not support the Model Context Protocol, the standard that lets other AI tools trigger and drive calls as part of a wider workflow. If you want a call to be one orchestrated step among many that an agent fires off, Vapi, Telnyx and ElevenLabs all support MCP and Retell does not.
- Less price control, because you cannot tune the components as cheaply. You pick the AI model on Retell, but the voice engine is a fixed rate you cannot shop around, and the speech-to-text is managed for you with no bring-your-own option. On a build-it-yourself platform you can swap a cheaper speech provider, run a cheaper model on simple questions, and bring your own carrier, and every saving shows on the bill. Retell trades that fine-grained control for a cleaner, more managed setup.
Now the five alternatives. Each beats Retell at one of those things.
Vapi: control and the lowest floor, if you have a developer
Switch to Vapi if you wanted component-level control that Retell does not give you. Vapi runs the call and charges $0.05 a minute to host it, and that is the only number Vapi sets. The three moving parts (turning speech into text, the AI working out a reply, and turning that reply back into a voice) are billed straight through from whoever you plug in, at their own rates, with no Vapi markup when you bring your own API keys. The phone line comes from your carrier. So the headline is a genuine floor, and a realistic all-in runs $0.05 to 0.30 a minute depending on the parts you wire in.
That is the whole point of Vapi, and the reason to leave Retell for it: you choose and pay for each piece, so you can run a cheaper model on simple calls or swap a speech provider to shave the rate. It also has the thing Retell lacks, MCP support, so other AI tools can trigger calls through it as one step in a bigger workflow. You can plug in your own phone-number supplier (SIP trunking), hand a live call to a human with the AI’s summary read to them first (a warm transfer), and launch whole outbound campaigns.
The honest catch is that this is more wiring than Retell. Where Retell hands you a managed setup in days, Vapi expects you to assemble the parts, so it really wants a developer to hand. HIPAA is available but it is a $2,000 a month add-on (against Retell’s Enterprise-plan BAA), and the language list is short too: English, Spanish, French and Italian. Pick Vapi if you want the lowest floor and real control and you have someone technical to set it up. If you wanted a single number on the invoice with no thinking, stay on Retell.
Bland: one flat predictable bill at volume
Switch to Bland if what you wanted from Retell was a single per-minute number you could budget against, with no component maths at all. Bland’s pitch is the opposite of build-it-yourself: one bundled rate covers the AI, the listening, the speaking and the phone line together, with nothing billed through from outside suppliers. It is $0.14 a minute on the entry tier, dropping to $0.12 with a $299 a month platform fee, and $0.11 at scale on a $499 a month plan. No surprise line items, which is the whole appeal for a team running phones at high volume who hated reconciling four suppliers’ bills.
Against Retell’s $0.13 to 0.31 range, Bland’s appeal is predictability rather than a lower ceiling: you know the number before the month starts. The compliance posture is genuinely strong, SOC 2 Type 1 and 2, HIPAA, GDPR and PCI DSS 4.0.1, and Bland says it built around those standards rather than bolting them on, which matters in a regulated industry. The number of calls it can run at once scales by tier and is unlimited on Enterprise, and the phone line is bring-your-own over any SIP provider.
The trade is the flip side of the bundle, and it is the same thing you would be leaving Retell to get less of: you do not pick the AI model or the voice the way you can on Retell or Vapi, so you are trusting Bland’s choices. Languages are English only, so this is a tighter box than Retell on coverage, not a wider one. Pick Bland if you run phones at volume and want one predictable bill, especially in a regulated industry. If you need to choose your own model or run in Spanish, look elsewhere.
Synthflow: no-code for a non-technical team
Switch to Synthflow if you wanted to ship an agent without touching code at all. Retell still expects a bit of setup; Synthflow is the no-code option, where you build the agent by dragging blocks around rather than wiring anything together, which is the draw for agencies and non-technical teams. Usage lands around $0.15 to 0.24 a minute: the Voice Engine is $0.09 (listening and speaking bundled), the AI model you choose adds $0.02 to 0.05, and the phone line is $0.02 on Synthflow’s managed Twilio, or nothing if you bring your own carrier. That floor sits above Retell’s, so you are paying for the no-code speed, not for a cheaper minute.
The compliance list is strong on paper, SOC 2, HIPAA, GDPR, PCI DSS Level 1 and ISO 27001, and it covers three languages (English, Spanish and German), one more than Retell. If you want to put your own branding on it and resell it (white-label), that is $2,000 a month on pay-as-you-go.
Now the part we have to flag, because Voxrater earns affiliate commissions and we will not pretend that away. Synthflow runs an affiliate programme, and there is a public, documented dispute about it. A public Trustpilot report describes an affiliate’s $10,840.55 commission marked approved and scheduled, then removed from the dashboard without a clear explanation, with the case escalated to German arbitration. That is the affiliate’s account as reported, and we have not independently verified the outcome. We flag Synthflow’s affiliate reliability as “caution” for that reason, and we would tell you the same whether or not we stood to earn from the link. Pick Synthflow if you want to ship without code and value that speed over fine-grained cost control, eyes open on the affiliate dispute if you plan to resell.
Telnyx: own the network, and reach 29 languages
Switch to Telnyx if your reasons for leaving Retell were the two-language ceiling and a wish to control the phone network itself. Most platforms, Retell included, rent their phone lines from someone else, usually Twilio, and stack the AI on top. Telnyx is the someone else: a licensed carrier that owns its network, so the SIP trunk, the phone numbers, the call routing and the AI agent all sit on one first-party stack. If telephony reliability and control are what you actually lose sleep over, that single fact is the reason to look here.
On languages it is in a different bracket from Retell: more than a thousand voices across about 29 languages, with cloning if you need a specific one, against Retell’s English and Spanish. It also has the features Retell lacks, MCP support for tools, plus warm transfer with context passing and batch calling, all in the product rather than on a roadmap. Pricing is itemised rather than one all-in number: the core agent is $0.05 a minute, speech-to-text is included, and text-to-speech (by the character) and the model (by the token) are billed on top. A cheap Telnyx-hosted model and a standard voice land you around $0.06 to 0.07 a minute; a frontier model and a premium voice climb toward $0.15 to 0.20.
The honest catch is the same one as Vapi: this is a developer platform, not a drag-and-drop builder, and the itemised pricing makes the final bill harder to predict than a flat rate. Some reviewers also report onboarding and number-provisioning friction, which matters if you need to be live next week (where Retell’s days-not-months speed is its whole pitch). One compliance note: Telnyx publishes SOC 2 Type 1 and 2, SOC 3 and GDPR, but HIPAA is referenced on some pages and not listed on the compliance article we read, so unlike Retell we leave it unticked until a BAA is confirmed in writing. Pick Telnyx if you want carrier-grade telephony you control and broad language coverage, and you have a developer. If you need no-code or a single predictable rate, Retell or Bland fit better.
ElevenLabs: when the voice and the language coverage matter most
Switch to ElevenLabs if the voice itself, or wide language coverage, is your deciding factor. This is the pick when the sound is the product: the library runs past 10,000 voices in 70-plus languages, the cloning is the best around, and on a blind listen most people cannot tell it from a human. Against Retell’s two languages, the 70-plus coverage is the headline difference, so if you localise widely this is the obvious move.
For a voice agent you pay by the minute: roughly $0.08 for the premium voice, plus your own AI model and about $0.02 for the phone line, so a realistic all-in lands $0.10 to 0.30 a minute, broadly in Retell’s range rather than below it. You are paying for the voice quality, not a cheaper minute. The model line-up matters: Flash v2.5 is built for real-time agents at about 75 milliseconds (that is ElevenLabs’ own figure for the model, not a latency we measured), while the richer v3 and Multilingual v2 trade a little speed for more expressive delivery. It also supports MCP, which Retell does not.
The catch is fit. ElevenLabs is aimed more at narration and video than busy phone lines, so it is less of a turnkey contact-centre setup than Retell and more a voice layer you build a call agent around. HIPAA, SOC 2 and GDPR sit on the Enterprise plan, so budget for that if you are in healthcare or the EU. Pick ElevenLabs if voice quality or language count is what you came for, and the call platform around it is something you are happy to assemble.
Where Retell still wins
Now the other side, because an alternatives page that only lists reasons to leave is not honest. Retell keeps the lead on the things that made it a sensible default.
Turnkey speed is the obvious one. Retell gets a working agent live in days with the call handling built in, where Vapi and Telnyx expect you to wire the parts yourself. It pairs that with a real dashboard and analytics out of the box, and a cleaner BAA path than most: HIPAA sits on the Enterprise plan, so a healthcare team contacts sales rather than paying a flat monthly HIPAA surcharge the way Vapi does at $2,000 a month. Retell also markets named customers including Everise and GiftHealth and says it serves more than 3,000 businesses; those are Retell’s own published figures, not numbers we verified, so read them as the company’s claim. And in our editorial preview it scores well on voice quality and ease of use.
So the honest shape is this: each alternative beats Retell at one job, and Retell beats most of them at being the fast, managed, get-live-this-week option. If your need is the one job, switch. If your need is “live quickly, handled for me, with a clean bill”, stay.
Before you switch, test these
A spec sheet will not tell you whether a platform fits your calls; a real test will. Before you move anything, run a small pilot on your own script, not the vendor’s demo:
- Your actual call, your actual numbers. Run a handful of real calls, the awkward objection, the number-heavy confirmation, the transfer to a human. Demos use the easy path. Yours is what ships.
- The thing you are switching for. If it is the floor price, put your real monthly minute volume through the cost calculator, because per-minute rates that look close diverge fast at scale. If it is languages, test every language you ship in, not just English. If it is MCP, wire one real tool call end to end before you commit.
- The compliance gate, in writing. If you need HIPAA, get the BAA confirmed before you build, on Telnyx especially, where we have left it unticked until that is in writing.
We have not placed our own scored test calls to any of these platforms yet, so the 1 to 10 numbers on the vendor pages are an editorial preview, not a measured result. When the benchmark calls land, they will replace our opinion with evidence.
Bottom line
Match the reason to the tool.
- Want the lowest floor and real control and you have a developer: Vapi, the cheapest starting point here with MCP.
- Want one flat predictable bill at volume in a regulated industry: Bland.
- Want to ship without code: Synthflow, eyes open on the affiliate dispute if you resell.
- Want carrier-grade telephony you control and 29 languages: Telnyx.
- Want the best voice and 70-plus languages: ElevenLabs.
- Want to be live in days, handled for you, with a clean bill: stay on Retell.
