  > Supported browser and server clients for the OpenVibe platform.
  
--**Status:** alpha, v0.121.0 (the five 1.0 core entries — `core`, `auth`, `events`, `db` and `media` — are frozen: their exported names change only with a major release; roadmap Wave 2; developer apps from Wave 20; Media objects v2 from Wave 4; the Tools platform API; Search, Chat, AI, Vision and consent clients; sign-in with recovery and a client health check). Every release is tagged (see [CHANGELOG.md](CHANGELOG.md)). Tested against local stub servers and the built-in mock platform only, never against the live platform. Services pin release tags; each repository's `STATUS.json` names the one it uses.

  **Plan:** OpenVibe End-to-End Realignment & Implementation Plan, revision 3 (20 Sep 2026), §3.2; roadmap §30.  
  **License:** MIT ([LICENSE](LICENSE)). This package is a library that apps outside the network embed, so it uses MIT. The OpenVibe services themselves stay AGPL-3.0.

  After v0.97.1 is tagged:
  
  ```bash
--npm install https://codeload.github.com/OpenVibers/OpenVibe.SDK/tar.gz/refs/tags/v0.121.0
++npm install https://codeload.github.com/OpenVibers/OpenVibe.SDK/tar.gz/refs/tags/v0.122.0
  ```
  
  It has no runtime dependencies. It needs Node ≥ 20, or any browser with `fetch`, Web Crypto and `TextDecoder`. There is no build step. The package is CommonJS with ESM entry points (`import` works). Each subpath has its own `.d.ts`. For a page with no bundler, `browser/openvibe-sdk.mjs` is one self-contained ES module of the browser-safe subpaths (see [Browser without a bundler](#browser-without-a-bundler)). It does not depend on `openvibe-contracts` at runtime: it copies the contract types it uses (from the temporary Contracts sharing branch, a devDependency the tests check them against).
