Vaani Developer Platform lets you build a voice AI agent without code — designing the call flow, handling objections, connecting tools and a knowledge base, and putting it live on a real phone number that outputs structured data after every call. It's freemium with a free tier, but the paid cost isn't stated as a flat number: pricing is usage-based and component-based (telephony, speech recognition, AI reasoning, voice synthesis, platform fee) on a prepaid wallet.

Vapi
Vapi (site) is an API-first platform for building voice AI agents, aimed squarely at developers rather than no-code users. It suits teams that want granular control over call logic and are comfortable integrating via code. Pricing is freemium: $5 free credits, pay-as-you-go hosting at $0.05/min, and paid "success packages" from $29/month (Core) up to $999/month (Pro), with custom pricing above that. Limitation: the jump from Core to Pro is steep, and Vaani's no-code approach may suit non-developers better.
Vomyra AI – Voice AI Agent
Vomyra AI (site) offers low-code and no-code voice agent building, similar in spirit to Vaani. It fits teams wanting a short, cheap trial before committing. There's a 7-day free trial for about $9.99 pay-as-you-go, then paid plans start around $187.50/month (Developer tier) or $249.99/month (Unlimited Solo). Limitation: once past the trial, monthly costs are notably higher and less granular than Vaani's component-based wallet pricing.
vyora.ai
vyora.ai (site) is a no-code AI calling agent pitched for Indian businesses, with setup claimed to take about 5 minutes. It suits small businesses wanting speed over configurability. The free plan gives 50 one-time credits that don't expire; paid plans start at roughly $10.56/month (Builder) and go up to a Business tier. Limitation: pricing is quoted in INR with approximate USD conversion, so actual cost may shift with exchange rates.
Vaaad AI
Vaaad AI (site) builds AI phone agents that call in 40 languages, suited to teams needing multilingual reach. Pricing is freemium: a free trial with ₹20 credits (about 4 minutes, no card needed), then a Pro Platform tier at roughly $30/month plus about $0.06/minute calling fees. Limitation: the free trial is very short, giving little room to test call quality before paying.
Trikon Voice
Trikon Voice (site) builds human-like AI voice agents built specifically for India, suited to higher-volume operations like call centers. It's paid only, with flat all-in pricing of about $0.048/minute covering STT, LLM, TTS, platform, and recording. Limitation: there's no free tier, and a minimum of 5,000 minutes per month is required to get this rate, which rules it out for small-scale testing.
VPIHub
VPIHub (site) offers AI speech agents integrated into business workflows. Who it suits is hard to pin down because pricing isn't stated anywhere in the brief, and there's no free tier listed. It may fit businesses willing to contact sales directly for a quote. Limitation: with no published pricing or free tier, it's difficult to compare cost upfront against Vaani or the other alternatives.
Vapi — secret code demo
This is Vapi's interactive demo (site), where users try to talk an AI voice agent into revealing a secret code. It suits people who want to sample Vapi's conversational voice quality before evaluating the main platform. No pricing is stated for this demo itself. Limitation: it's a demo/showcase rather than a standalone product, so it's not a direct substitute for Vaani's full build-and-deploy workflow.
How to choose
If you want no-code building like Vaani, start with Vomyra AI or vyora.ai. If you're a developer who wants API-level control, Vapi is the closer match. For high-volume, India-specific calling with flat per-minute pricing, look at Trikon Voice; for multilingual reach, consider Vaaad AI. Skip VPIHub until you have a quote in hand, since no pricing is published.
