Redocly vs Transmission: at a glance
What is Redocly?
Redocly fixes EU-region SSO and log-retention limits in three platform releases in one day.
Redocly ships platform builds daily. After renaming `reunite` to `platform` in config 0.70.0 and wiring it through Platform v2026-10-31.1, three November 2 releases fixed SSO failing for EU-hosted projects without `access.residency`, an organization switcher that ignored SSO-required orgs, runtime logs showing more history than the plan allows, and a hidden team-manager list after plan downgrades.
What is Transmission?
Transmission rewrote its RPC API to JSON-RPC 2.0 — then the 4.1 beta train stalled.
The whole visible history is the 4.1.0 beta series, running from December 2024 to January 2026 and developed in parallel with the 4.0.x bug-fix line since 2023. Across those betas the client picked up sequential downloading, a selectable µTP-versus-TCP preferred transport, proxy support for web connections, IPv6 and dual-stack UDP trackers, native platform icons, and a JSON-RPC 2.0-compliant RPC API with snake_case unified across RPC and settings.json. Feature freeze was declared at beta.5 in January 2026, and nothing has shipped since.

Redocly
6.3INFRA · APIS
Redocly fixes EU-region SSO and log-retention limits in three platform releases in one day.
◆ Current state
Redocly ships platform builds daily. After renaming `reunite` to `platform` in config 0.70.0 and wiring it through Platform v2026-10-31.1, three November 2 releases fixed SSO failing for EU-hosted projects without `access.residency`, an organization switcher that ignored SSO-required orgs, runtime logs showing more history than the plan allows, and a hidden team-manager list after plan downgrades.
◆ Where it's heading
Recent work concentrates on access control and plan enforcement around SSO, data residency and RBAC, next to the rename and the AI agent's support-desk features. The fixes suggest region-specific hosting and plan tiers are still being hardened.
◆ Prediction
Expect more access and plan-boundary fixes in daily platform builds, and further support-desk features for the agent; when the `reunite` key will stop working is unclear.
Transmission
0.0INFRA · APIS
Transmission rewrote its RPC API to JSON-RPC 2.0 — then the 4.1 beta train stalled.
◆ Current state
The whole visible history is the 4.1.0 beta series, running from December 2024 to January 2026 and developed in parallel with the 4.0.x bug-fix line since 2023. Across those betas the client picked up sequential downloading, a selectable µTP-versus-TCP preferred transport, proxy support for web connections, IPv6 and dual-stack UDP trackers, native platform icons, and a JSON-RPC 2.0-compliant RPC API with snake_case unified across RPC and settings.json. Feature freeze was declared at beta.5 in January 2026, and nothing has shipped since.
◆ Where it's heading
The interesting work is at the integration boundary, not in the download engine: the RPC surface has been standardised and renamed, and beta.5 was largely spent repairing what those changes broke, including backwards-incompatible keys accidentally written into settings files. That is the cost profile of an API migration in a project with a large ecosystem of third-party remotes. With feature freeze held for seven months and no 4.1.0 final, the release is late relative to its own stated plan.
◆ Prediction
The next release should be 4.1.0 final or a further beta rather than new features, since the branch is frozen — but the entries give no signal on what is holding it.
