- ---- - -**Vexa** is an open-source, self-hostable meeting bot API and meeting transcription API for Google Meet, Microsoft Teams, and Zoom. Alternative to Recall.ai, Otter.ai, and Fireflies.ai — self-host so meeting data never leaves your infrastructure, or use [vexa.ai](https://vexa.ai) hosted. - ---- - -**Data sovereignty** — self-host so meeting data never leaves your infrastructure - -**Cost** — replace $20/seat SaaS with your own infrastructure - -**Embed in your product** — multi-tenant meeting bot API with scoped tokens - -**AI agents** — MCP server with 17 tools - ---- - -### Capabilities - - -| | | -| --- | --- | -| **Meeting bot API** | Send a bot to any meeting: auto-join, record, speak, chat, share screen. Open-source alternative to [Recall.ai](https://recall.ai). | -| **Meeting transcription API** | Real-time transcripts via REST API and WebSocket. Self-hosted alternative to Otter.ai and Fireflies.ai. | -| **Real-time transcription** | Sub-second per-speaker transcripts during the call. 100+ languages via Whisper. WebSocket streaming. | -| **Interactive bots** | Make bots speak, send/read chat, share screen content, and set avatar in live meetings. | -| **Browser bots** | CDP + Playwright browser automation with persistent authenticated sessions via S3. | -| **MCP server** | 17 meeting tools for Claude, Cursor, Windsurf. AI agents join calls, read transcripts, speak in meetings. | -| **Multi-tenant** | Users, scoped API tokens, isolated containers. Deploy once, serve your team. | -| **Dashboard** | Open-source Next.js web UI — meetings, transcripts, agent chat, browser sessions. Ready to use out of the box. | -| **Self-hostable** | Run on your infra. Meeting data never leaves your infrastructure. | - - -Every feature is a separate service. Pick what you need, skip what you don't. Self-host everything or use [vexa.ai](https://vexa.ai) hosted. - ---- - -## Why Self-Host Meeting Transcription? - -**For regulated industries** — banks, financial services, healthcare — meeting data can't leave your infrastructure. Self-hosting Vexa means zero external data transmission and full audit trail on your own infrastructure. - -**For cost-conscious teams** — replace per-seat SaaS pricing. A team paying $17/seat/mo for meeting transcription can self-host Vexa and drop that to infrastructure cost. - -**For developers** — embed a meeting bot API in your product. Multi-tenant, scoped API tokens, no per-user infrastructure. - -Build meeting assistants like Otter.ai, Fireflies.ai, or Fathom — or build a meeting bot API like [Recall.ai](https://recall.ai) — self-hosted on your infrastructure. - -- **Vexa (self-host)** — your infra cost. Data never leaves your infrastructure. Meeting bot API, real-time transcription, interactive bots, MCP server. Open source, Apache 2.0. Google Meet, Teams, Zoom*. -- **Recall.ai** — $0.50/hr. No self-hosting. Meeting bot API, real-time transcription. No MCP, limited interactive bots. Closed source. Meet, Teams, Zoom, Webex. -- **Otter.ai** — $17-20/seat/mo. No self-hosting. No API. Limited real-time transcription. Closed source. Meet, Teams, Zoom. - -\* Zoom support is experimental - -Or use [vexa.ai](https://vexa.ai) hosted — get an API key and start sending bots immediately, no infrastructure needed. - -## Built for Data Sovereignty - -Meeting data never leaves your infrastructure. Self-host for complete control. Modular architecture scales from edge devices to millions of users. - -**1. Hosted service** -At [vexa.ai](https://vexa.ai) — get an API key and start sending bots. No infrastructure needed. -*Ready to integrate* - ---- - -**2. Self-host with Vexa transcription** -Run Vexa yourself, use vexa.ai for transcription — ready to go, no GPU needed. -*Control with minimal DevOps* — see [deploy/](./deploy/) for setup guides. - ---- - -**3. Fully self-host** -Run everything including your own GPU transcription service. -*Meeting data never leaves your infrastructure* — see [deploy/](./deploy/) for setup guides. - -## What's new - -**v0.10 — full architecture refactor** - -- **Services refactored** — runtime-api as infrastructure layer (container orchestration), meeting-api as data layer, agent-api as high-level intelligence layer. Clean separation of concerns. -- **Real-time pipeline moved into bots** — transcription pipeline now runs inside bot containers, eliminating external dependencies -- **Agent API** *(experimental)* — ephemeral containers for AI agents. See [services/agent-api/](./services/agent-api/). -- **Helm/K8s** — production Kubernetes deployment with built images and global.imageTag support - -**v0.9** - -- **Zoom** *(experimental)* — initial Zoom Meeting SDK support -- **Interactive Bots API** — speak, chat, screen share, avatar controls during live meetings -- **MCP server** — 17 tools for AI agents -- **Recordings** — S3-compatible storage - ---- - -> See full release notes: [https://github.com/Vexa-ai/vexa/releases](https://github.com/Vexa-ai/vexa/releases) - ---- - -## Quickstart - -### Self-host with Docker - -On a fresh Linux machine (Ubuntu 24.04): - -```bash -apt-get update && apt-get install -y make git curl -curl -fsSL https://get.docker.com | sh -git clone https://github.com/Vexa-ai/vexa.git && cd vexa -``` - -Then choose: - - -| Command | What you get | Best for | -| ------------ | -------------------------------- | --------------------------- | -| `make lite` | Single container, all services | Quick evaluation, small teams | -| `make all` | Full stack, each service separate | Development, production | - - -Both prompt for a transcription token on first run.
