Fission vs ToolJet: at a glance
What is Fission?
Fission's release feed carries only RC tags, and none of them say what shipped
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
What is ToolJet?
ToolJet ships Custom Component Library and tightens enterprise controls on path to AI-native low-code.
ToolJet is running two parallel tracks: an LTS branch delivering incremental reliability and plan-level limit expansions, and a beta track already carrying LLM provider switching, MCP bundled into the EE image, Personal Access Tokens, and 2FA. The gap between beta and stable is where the platform's real direction lives — AI builder + enterprise security controls converging into a single product.

◆ Current state
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
◆ Where it's heading
What can be read from these tags is infrastructure maintenance rather than product direction: Go dependency updates, helm and kind and skaffold and cosign version refreshes, and regenerated swagger and applyconfiguration files kept in sync with CEL and webhook validation comments in the core API types. That last one is the only entry hinting at anything structural — CEL-based validation on the API types implies declarative validation moving into the CRDs — but the commit itself changes only generated output.
◆ Prediction
This feed does not carry enough to predict product direction; until final releases or their notes appear here rather than only candidate tags, any read of where Fission is heading would be guesswork.
ToolJet
6.3INFRA · APIS
ToolJet ships Custom Component Library and tightens enterprise controls on path to AI-native low-code.
◆ Current state
ToolJet is running two parallel tracks: an LTS branch delivering incremental reliability and plan-level limit expansions, and a beta track already carrying LLM provider switching, MCP bundled into the EE image, Personal Access Tokens, and 2FA. The gap between beta and stable is where the platform's real direction lives — AI builder + enterprise security controls converging into a single product.
◆ Where it's heading
The consolidation of tooljet-mcp into the EE production image is the clearest signal: ToolJet is treating MCP as a first-class integration layer, not an experiment. PATs threading through groups, workflows, plugins, and MCP auth suggest an API-first model is being built on top of the visual layer. The Custom Component Library core gives power users the extensibility path that previously required forking the platform.
◆ Prediction
LLM provider switching and MCP-based datasource connectivity will stabilize to LTS within the next few releases — both are already merged in EE. Once stable, these features position ToolJet against agentic-workflow tools as much as against no-code competitors.
