What we know about Rapida
Rapida is a voice ai platform: open-source (GPL-2.0 + branding terms) voice AI orchestration platform in Go/gRPC, aimed at agencies, CPaaS/CCaaS providers, and enterprises wanting white-label, multi-tenant voice operations with provider-level cost passthrough. This profile tracks every Rapida fact we have verified, each linked to a primary source and dated.
On pricing, Rapida starts at $0.01 per minute for its entry tier. That is the sticker rate: real production cost usually runs higher once you add a language model, a voice provider, and telephony minutes.
New Rapida accounts get Launch plan free: 1 agent, BYO providers to test with before a card is required, which is enough to run a handful of real calls and judge latency and voice quality for your own script rather than a demo.
On capabilities, Rapida covers llm/tts costs passed through at cost?, native sip trunking, bring-your-own llm, bring-your-own tts voice, self-host / on-prem option, and self-serve signup. Each of those is verified against Rapida's own docs or dashboard, not marketing copy.
On performance, Rapida reports 200 concurrent sessions concurrent calls on the base plan. Latency figures are vendor claims until we measure them ourselves, and they are labeled that way on the Rapida fact sheet, so treat them as a starting point rather than a guarantee.
Placed against the 23 voice ai tools we track, Rapida's strongest showing is the 2nd-cheapest per-minute rate - a spread worth weighing against your own priorities.
In total we track 13 verified facts for Rapida today, each linking the primary source it came from so you can check our work - and vendor claims we have not measured ourselves are labeled as such on the Rapida fact sheet below.
