The bottom line
Choose start.chat if you want:
- AI that actually does things — agents with abilities that search, query data, run actions, and automate. Per-channel configuration so your support channel gets a different personality than engineering. External agents via OpenClaw webhook.
- Search that works — full-text + fuzzy matching (handles typos) + semantic search (SQLite vectors). You find what you’re looking for even when you don’t remember the exact words.
- A real platform — apps with React UI blocks, structured data, scheduled backends, flow automation. Need an integration we don’t have? We generate custom apps within an hour on request.
- A hosted product you can extend — build against the API, SDK, apps, and flows today. Source and self-hosting are not public yet; see Software Availability and Rights for the current status.
- A lightweight desktop app — native Tauri app (~15MB, low RAM) vs Electron bloat.
- Offline-first — full read/write offline, automatic sync when connected.
Choose Slack if you need:
- Ecosystem maturity — 2,600+ apps in the directory, widespread adoption
- Enterprise compliance — SOC 2 Type II, HIPAA, FedRAMP, eDiscovery
- SSO breadth — SAML, SCIM, Okta, Azure AD out of the box
- Slack Connect — mature cross-organization channels
- Market familiarity — your team already knows how to use it
Choose Discord if you need:
- Massive community scale — millions of concurrent users in public servers
- Voice-first experience — persistent voice channels, spatial audio, streaming
- Gaming integrations — deep ties to game platforms, streaming, Nitro perks
- Large bot ecosystem — thousands of community-built bots
