Compatibility
| Surface | Current evidence |
|---|---|
| Web | Current development candidate: web 0.23.0 with instance 0.24.0. Installed recovery qualification is in progress. |
| Local installer | Current candidate requires installer 0.3.4; local Wrangler/workerd, D1 and private R2. |
| D1 / PostgreSQL | Both have local persistence and Worker tests. The installer currently targets local D1 only. |
| Customer Cloudflare / Hyperdrive | Customer-instance production deployment and managed-provider qualification remain unfinished. This is separate from the public website. |
| macOS / iOS / Android | Native implementations are in development. Build and limited platform evidence exist; full device, signing, distribution and calling qualification remain open. |
| Windows / Linux | Required desktop targets. No production client or platform qualification is claimed. |
Still required
Complete native qualification, MFA and remaining recovery paths, external notification delivery, Slack migration, complete backup/restore, third-party app execution and MCP remain required work. Enterprise identity, governance, calling and provider integrations are unfinished.
Search, profiles, pins, saved messages, mentions and the in-app notification inbox have bounded local implementations. That evidence does not establish complete product acceptance, live provider operation, production scale or an uptime commitment.
Packages and source
Public release downloads are not connected here. Eligible customers receive verifiable packages and source under commercial terms through distribution. A download hash supports integrity; trusted signing metadata is also required.
Public package downloads are not available from this site yet.
Upgrade and recovery limits
The local installer verifies the exact plan and rejects incompatible releases and altered artifacts. Contract migrations require stopped writers and a compatible new runtime. Code rollback does not undo database changes; the local relational export is not a complete R2 or provider backup. Full restore and cloud rollback remain required work.
