## SDK overview

- **[React.js (Web)](https://github.com/dappros/ethora-chat-component)** — Flagship SDK, fullest feature coverage. Effectively the JS/TS reference.
- **[React Native](https://github.com/dappros/ethora-chat-component-rn)** — Mobile React Native. Shares architecture with React.js but trails on reactions and notifications.
- **[Android (Kotlin)](https://github.com/dappros/ethora-sdk-android)** — Native Kotlin + Jetpack Compose. JitPack-distributed. No account provisioning APIs.
- **[iOS (Swift)](https://github.com/dappros/ethora-sdk-swift)** — Native SwiftUI via SPM. Tracks Android closely; no logout helper or dark mode yet.
- **[WordPress](https://github.com/dappros/ethora-wp-plugin)** — Bot-widget plugin, not a full chat SDK. Embeds a single bot-to-user widget.

## Methodology

Statuses are based on direct code audit (file-level inspection, not just README claims). Each feature has a stable ID so it survives renames. "Partial" is used when a config / model / stub exists but the end-to-end flow isn't wired.

## Updating this matrix

1. Edit `features.yaml` — the single source of truth.
2. Run `cd features/scripts && npm install && npm run render` to regenerate `README.md` and `views/by-category.md`.
3. Commit both the YAML and rendered output so diffs are visible in PRs.
