ToolJet vs Transmission
A side-by-side editorial comparison of ToolJet and Transmission — release velocity, themes, recent moves, and the top alternatives to consider.
ToolJet vs Transmission: at a glance
What is ToolJet?
ToolJet's beta adds data source folders, database environments and git sync for workflows.
ToolJet runs two release lines: an LTS track that took AI Builder releases 4 and 5 and a custom-component CLI in late October, and a beta track that moves faster. Beta v3.21.87 on November 2 adds folders for data sources, environments for ToolJet Database, and git sync for workflows. The same release closes several tenant-isolation bugs, including an IDOR in page and component lookups and imports that trusted a client-supplied organization ID.
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.

ToolJet
5.0INFRA · APIS
ToolJet's beta adds data source folders, database environments and git sync for workflows.
◆ Current state
ToolJet runs two release lines: an LTS track that took AI Builder releases 4 and 5 and a custom-component CLI in late October, and a beta track that moves faster. Beta v3.21.87 on November 2 adds folders for data sources, environments for ToolJet Database, and git sync for workflows. The same release closes several tenant-isolation bugs, including an IDOR in page and component lookups and imports that trusted a client-supplied organization ID.
◆ Where it's heading
The beta line is filling in the structure larger teams need, with environments, folders, version control and permission scopes, while the LTS line absorbs AI Builder releases a few days at a time. The security fixes in the same beta point to an audit of multi-tenant boundaries.
◆ Prediction
Expect the beta's environments, folders and tenant-isolation fixes to reach the LTS line in a coming patch, as AI Builder releases did in October.
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.
