Parse Server vs Transmission
A side-by-side editorial comparison of Parse Server and Transmission — release velocity, themes, recent moves, and the top alternatives to consider.
Parse Server vs Transmission: at a glance
What is Parse Server?
Parse Server's alpha channel has become a steady stream of access-control security fixes.
Recent Parse Server releases are almost entirely security and permission fixes on the 9.10.x alpha line. Several close advisories where callers without read access could learn whether a field exists or receive data from internal classes, including a LiveQuery leak of installation objects. The newest alpha moves the Docker image from Node.js 20 to 24.
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.

Parse Server
5.0INFRA · APIS
Parse Server's alpha channel has become a steady stream of access-control security fixes.
◆ Current state
Recent Parse Server releases are almost entirely security and permission fixes on the 9.10.x alpha line. Several close advisories where callers without read access could learn whether a field exists or receive data from internal classes, including a LiveQuery leak of installation objects. The newest alpha moves the Docker image from Node.js 20 to 24.
◆ Where it's heading
The project is working through a systematic audit of how read permissions are enforced across save, create, dot-notation and LiveQuery paths, shipping one fix per alpha. Small performance work, such as dropping an extra database read on save, appears alongside. Feature work is not visible in this window.
◆ Prediction
More permission-boundary advisories are likely in the next few alphas, followed by a stable 9.10.x release that bundles them. The entries don't indicate when the audit will end.

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.
