That number covers platform hosting only. Model costs, telephony, and concurrency limits stack on top of it. Add [HIPAA compliance](https://www.hhs.gov/hipaa/index.html) at $2,000/month, or zero data retention at $1,000/month. The real bill climbs fast. Vapi also assumes you have a developer on staff. It's infrastructure, not a finished system. Someone still has to design the conversation, wire the telephony, and keep it running. Vapi has real scale behind it — over 100,000 developers build on the platform today. But scale doesn't shrink the invoice. It just means more people are learning that lesson at once. This guide covers five alternatives that keep total cost down. Not just the number on the pricing page. Some are done-for-you systems built for operators. Others are cheaper developer platforms. One is [open-source](https://opensource.org/osd) enough to self-host for close to nothing. ## What are the most affordable alternatives to Vapi for voice AI? Voicetta is the cheapest done-for-you option. No developer required to deploy it. Retell AI gives developers fast deployment with pay-as-you-go pricing and no platform fee to start. Bland AI charges one flat per-minute rate. LLM, speech-to-text, and text-to-speech are bundled in, with no separate model bills. LiveKit Agents is the cheapest option of all for technical teams willing to self-host. Cartesia Line rounds out the list for teams where speech latency matters most. Its pricing holds up well too. | Platform | Starting Price | Best For | Key Differentiator | Free Trial | | --- | --- | --- | --- | --- | | Voicetta | Custom (DFY); BYOK ~1.6¢/min infra | Operators without a developer on staff | Done-for-you system; one shared memory across voice, SMS, WhatsApp | Contact for demo | | Retell AI | $0 platform fee; ~7–31¢/min blended | Developers who want fast, flexible deployment | Voice, chat, SMS, and email from one platform | Yes ($10 credit) | | Bland AI | $0.14/min, no monthly fee (Start plan) | Teams that want one bundled rate, no line items | LLM, STT, and TTS priced as a single number | Yes (2 credits + free number) | | LiveKit Agents | Free (1,000 min); $50/mo Ship plan | Engineering teams that want full control | Open-source; fully self-hostable | Yes (1,000 min, no card) | | Cartesia Line | Free ($1 credit); ~7.4¢/min all-in | Teams where TTS latency is the deciding factor | Sub-100ms synthesis via Sonic; free LLM tier | Yes ($1 prepaid credit) | ## 1. Voicetta: done-for-you voice AI, priced for operators without a dev team > **Heads up:** Voicetta is ours. We think it earns its place on this list, especially on cost — but we're obviously not a neutral judge here. Voicetta doesn't sell infrastructure. It builds and runs the whole system for you. The agent, the workflows, the telephony, the reporting — all of it. Founder Rafał Florek built his first voice agent in 2019, for his own hotel. That operational background shapes how the product handles pressure. Unlike Vapi, there's nothing to assemble yourself. Voicetta configures the execution layer. You just review the results. ### What it offers Voicetta runs across voice, SMS, and WhatsApp on one shared memory. A Guest never repeats themselves between channels. Voicetta calls this its "[one brain, every channel](https://voicetta.com/docs/conversation-memory)" model. Outbound is a core capability here, not an afterthought. Booking confirmations, pre-arrival reminders, and post-stay follow-ups all run alongside inbound calls. AI Evaluations, shipped in [v3.4](https://voicetta.com/docs/ai-evaluations), grades every call and text thread. You write the criteria yourself. Each verdict comes with a plain-language reason. ### What you'll actually pay On the BYOK tier, infrastructure runs about [1.6¢ per minute](https://voicetta.com/pricing). That's 1.2¢ for voice infrastructure and 0.4¢ for domestic telephony. AI provider costs bill separately, at your provider's own rate. The first 1,000 Guests on a workspace pay $0 platform fee. That rate locks in permanently for those Guests. Standard pricing applies only after that. Voicetta's own rate card puts BYOK inbound near $16 per 1,000 minutes. Vapi runs an estimated $50–60 on comparable usage. That's a vendor-sourced comparison, so treat it as directional. Teams that don't want to manage AI provider accounts can use Managed AI instead. Rates start around 12.4¢/min and reach 40.6¢/min for the Realtime tier. ### Strengths and trade-offs **Strengths:** No developer needed to deploy or maintain it. Cross-channel memory means one conversation, not three disconnected bots. Every call and text thread gets graded automatically, not just a sample. **Trade-offs:** Custom pricing means no self-serve checkout — you talk to sales first. It's built for hospitality, real estate, and property management specifically, not general-purpose development. ### Who it's built for Hotel operators, real estate brokerages, and property managers who feel the cost of missed calls. Most don't have engineering time to spend on voice infrastructure. Best Of Best Reviews named Voicetta its "Best System for Fixing Costly Business Calls in the U.S." for 2026. That came from real deployments, not a demo. --- ## 2. Retell AI: pay-as-you-go infrastructure with no platform fee to start Retell AI is a developer platform for building voice agents. It's similar in spirit to Vapi, but priced differently at the entry level. There's no monthly platform fee on the pay-as-you-go plan. In January 2026, Retell expanded past voice. It added chat, SMS, and email from the same platform. That move puts pressure on Vapi's voice-only positioning. Vapi charges a flat $0.05/min hosting fee before anything else. Retell's entry point is $0 down, with $10 in free credit to start testing. ### What it offers Retell Voice Infra is priced separately from the model layer. You can mix and match. Core infrastructure runs $0.055/min, with telephony added at $0.015/min. Retell Assure, launched in late 2025, adds automated QA scoring on calls. It's a step toward the observability layer Vapi doesn't offer natively. The platform also supports 20 concurrent calls for free. Per-call fees only kick in past that, which matters when testing at real volume. ### What you'll actually pay Text-to-speech runs $0.015–$0.040/min, depending on the provider you choose. LLM costs vary the most. Lighter models run $0.003/min; top-tier reasoning models reach $0.16/min. Blended together, a typical deployment lands between 7¢ and 31¢ per minute. That's a wide spread, and model choice is the real lever on cost. A knowledge base add-on runs $0.005/min. Phone numbers cost $2/month. Concurrency past the free 20 calls runs $8/month per line. ### Strengths and trade-offs **Strengths:** No platform fee to get started, unlike Vapi's flat $0.05/min. Multi-channel from one account. Retell Assure adds QA visibility most infrastructure platforms skip. **Trade-offs:** Still requires a developer to design and maintain the agent. The wide cost range makes budgeting harder than a flat-rate competitor. No done-for-you option exists here. ### Who it's built for Technical teams that want infrastructure control like Vapi's. But with a lower entry cost, and less commitment before the use case is proven. --- ## 3. Bland AI: one bundled rate instead of four separate line items Bland AI takes a different approach than Vapi or Retell. Instead of separate charges for infrastructure, LLM, STT, and TTS, everything folds into one rate. The Start plan runs $0.14/min, with no monthly platform fee. Sign up, get two free credits and an inbound number, and start testing right away. That's simpler to budget than Vapi. Vapi's $0.05/min hosting fee is only the starting line, not the total. ### What it offers Bland markets itself around call realism first. But the pricing structure is what earns it a spot here. There's no separate model bill arriving on top of your invoice. Build ($299/month) and Scale ($499/month) plans lower the rate to $0.12 and $0.11 per minute. Those fit teams with higher call volume. Transfer minutes — calls handed to a human — bill separately. Expect $0.03–$0.05/min, depending on plan tier. ### What you'll actually pay At low volume, the Start plan is the simplest entry point on this list, next to LiveKit's free tier. No platform fee eats into the budget before a single call happens. At higher volume, Build or Scale trades a monthly fee for a lower per-minute rate. Run the math against your expected call volume first. ### Strengths and trade-offs **Strengths:** One number to budget against, not four. No card required to start testing. Strong developer mindshare and documentation. **Trade-offs:** No hospitality or operational philosophy — it's a general-purpose calling API. Still requires development resources to build and maintain an agent. The per-minute rate runs higher than Retell's infrastructure-only entry price. ### Who it's built for Developers who want predictable, bundled pricing. Nobody wants to reconcile four separate line items every billing cycle. --- ## 4. LiveKit Agents: the cheapest option, if your team can self-host LiveKit started as open-source real-time communication infrastructure. The Agents framework adds voice AI on top of it. Its pricing is more transparent than most platforms on this list. The free Build tier includes 1,000 agent session minutes. It also includes a US phone number and 50 inbound telephony minutes. No credit card required. The core framework is open-source. Teams with the infrastructure capacity can self-host it and cut cloud costs to almost nothing. ### What it offers The Ship plan ($50/month) includes 5,000 agent session minutes, with overage at $0.01/min. That's a fraction of Vapi's $0.05/min hosting fee for the same layer. Every component — session time, telephony, STT, LLM, TTS — is priced separately. There's no bundled margin hiding inside one quoted number. An optional observability add-on runs $0.01/min. It gives visibility into production call behavior that most infrastructure platforms charge more for, or skip entirely. ### What you'll actually pay Blending mid-tier AI models with LiveKit's session and telephony fees lands around 6.7¢/min all-in. That's among the lowest total costs on this list, Vapi included. The Scale plan ($500/month) drops the overage rate further. It also adds inference pricing discounts for teams running real production volume. Self-hosting removes cloud fees entirely. In exchange, your team owns the operational overhead of running the infrastructure. ### Strengths and trade-offs **Strengths:** The lowest floor of any platform here, especially self-hosted. Transparent, per-layer pricing with no bundled surprises. A large, active open-source community stands behind it. **Trade-offs:** Requires real developer resources to assemble and maintain — more than Vapi, not less. No done-for-you path exists. Observability is billed separately, not included by default. ### Who it's built for Engineering teams comfortable with component-level infrastructure. They want the lowest possible cost, and full control over where it runs. --- ## 5. Cartesia Line: built for latency, priced competitively Cartesia is best known for Sonic, its text-to-speech model. It's tuned for sub-100ms synthesis. Line is the voice agent built on top of it, and it competes on price too. The free tier includes $1 in prepaid agent credit. No upfront commitment required. Paid tiers run from $5/month (Pro) to $299/month (Scale). A 200ms delay is noticeable to callers on some use cases. For those teams, Cartesia's latency focus is the reason to look past the sticker price entirely. ### What it offers The base call rate is $0.06/min. Telephony adds $0.014/min for a Cartesia-provided number, landing around 7.4¢/min all-in. LLM usage is currently free for agents built in Cartesia's UI. That free LLM tier is limited-time. But it means Cartesia's effective rate can beat Vapi's $0.05/min hosting fee once model costs get counted. Higher tiers unlock commercial licensing and instant voice cloning. That's useful for teams building a distinct branded voice, not a stock one. ### What you'll actually pay Billing runs on prepaid credit, not a strict per-minute invoice. Translating credits into minutes takes some math to compare cleanly against other platforms. The free LLM tier won't last forever. Once it ends, standard model costs — roughly 0.4–2¢/min — stack onto the base rate. ### Strengths and trade-offs **Strengths:** Sub-100ms TTS latency, among the fastest available anywhere. A free plan with no card required. LLM costs currently included at no charge. **Trade-offs:** Cartesia is primarily a TTS company. Agent capabilities are newer than platforms built voice-first. The free LLM tier is explicitly temporary. ### Who it's built for Teams building latency-sensitive voice applications. The gap between 100ms and 300ms of synthesis delay genuinely changes how a call feels. ## Frequently asked questions **Why look for a Vapi alternative in the first place?** Vapi's $0.05/min rate is the platform fee only. Add model costs, concurrency limits, and optional compliance add-ons. The real bill runs well past the number on the pricing page. **Do any of these alternatives skip the need for a developer entirely?** Yes — Voicetta. Retell AI, Bland AI, LiveKit Agents, and Cartesia Line sit in Vapi's own category. They all still need someone to build and maintain the agent. **Which option is cheapest for a low-volume test?** LiveKit Agents' free tier runs 1,000 minutes with no card. Bland AI's Start plan gives two free credits with no monthly fee. Cartesia's $1 free credit works the same way. **What's the real trade-off between Vapi and these alternatives?** Vapi has the largest developer ecosystem and the most third-party tutorials. That shortens the learning curve. These alternatives compete on lower total cost, bundled pricing, self-hosting, or skipping the developer step entirely. **How do I compare per-minute rates that are structured so differently?** Convert every platform to an estimated all-in rate. Add infrastructure, telephony, STT, LLM, and TTS at your expected model choice. A $0.05/min quote and a $0.06/min quote aren't comparable until you know what's inside each one. **Is a done-for-you system like Voicetta more expensive than building on infrastructure?** Not necessarily. Voicetta's BYOK tier runs about 1.6¢/min on infrastructure alone. That's competitive with the developer platforms here — without the engineering time it takes to assemble and maintain them. ## Conclusion: match the alternative to who's building it No developer on the team? Voicetta is the option that doesn't require one. It's built for operators — hospitality, real estate, property management — who need the system running, not a project to manage. Have engineering resources and want to move fast without Vapi's flat hosting fee? Retell AI's pay-as-you-go entry and multi-channel reach are worth testing first. Budgeting simplicity matters more than the lowest possible rate? Bland AI's single bundled number is easier to forecast than four separate line items. Cost is the only variable that matters, and your team can self-host? LiveKit Agents goes lower than anything else here, Vapi included. Voice latency is the thing your callers actually notice? Cartesia Line's Sonic-powered speed is worth the look, at a price that holds up against the rest of this list. Bad calls cost money, whichever platform ends up running them. If you'd rather not assemble the pieces yourself, [Voicetta](https://voicetta.com/) will build the system for you. Book a demo and see what it costs to run yours. No developer required, no infrastructure to maintain.
