What is ToolJet?

ToolJet ships AI Builder release 4 to its LTS line, with Gemini 4 Argon support.

ToolJet's LTS v3.20.250 brings AI Builder release 4 into the enterprise edition, with cancellation handling and Gemini 4 Argon as a model option; v3.20.248 added workspace MCP OAuth with SSO login. The beta line spent the week on Node 22.23.4 for the October security release, file-permission and license-check fixes, a page-panel crash fix, and an environment flag that limits ToolJet Database edits to admins.

What is Windmill?

Windmill is building a full AI-native workflow platform — guest app access, agent evals, dbt runtime, and AI cost tracking shipped in rapid succession.

Windmill is an open-source workflow automation and developer platform that has been adding AI capabilities at an accelerating rate. The last month brought AI agent evaluations (with dataset-based scoring and run comparison), AI usage and cost tracking per user and model, a Plan mode for AI sessions (read-only investigation posture), version history for both AI artifacts and resource values, and nested filter groups for Kafka and WebSocket triggers. The platform now spans workflow orchestration, AI-assisted script writing, and a native dbt runtime.

ToolJet ships AI Builder release 4 to its LTS line, with Gemini 4 Argon support.

◆ Current state

ToolJet's LTS v3.20.250 brings AI Builder release 4 into the enterprise edition, with cancellation handling and Gemini 4 Argon as a model option; v3.20.248 added workspace MCP OAuth with SSO login. The beta line spent the week on Node 22.23.4 for the October security release, file-permission and license-check fixes, a page-panel crash fix, and an environment flag that limits ToolJet Database edits to admins.

◆ Where it's heading

The AI Builder work that sat in beta is now reaching LTS customers, alongside MCP connections that respect SSO. Most other changes on both lines are security bumps and hardening, which fits a product selling to enterprises that run the LTS track.

◆ Prediction

Expect AI Builder to keep adding models and EE controls on LTS, and more admin-level permission flags like the database-edit restriction.

Windmill is building a full AI-native workflow platform — guest app access, agent evals, dbt runtime, and AI cost tracking shipped in rapid succession.

◆ Current state

Windmill is an open-source workflow automation and developer platform that has been adding AI capabilities at an accelerating rate. The last month brought AI agent evaluations (with dataset-based scoring and run comparison), AI usage and cost tracking per user and model, a Plan mode for AI sessions (read-only investigation posture), version history for both AI artifacts and resource values, and nested filter groups for Kafka and WebSocket triggers. The platform now spans workflow orchestration, AI-assisted script writing, and a native dbt runtime.

◆ Where it's heading

The pattern across recent releases is clear: Windmill is building the operational infrastructure around AI agents — not just the ability to run them, but the ability to measure, control, audit, and govern them. Agent evals add a testing layer; Plan mode adds a safety posture; cost tracking adds financial visibility; version history adds rollback capability. The guest app access model also introduces a new monetization dimension (4:1 guest-to-seat ratio above 100 free guests). Windmill is positioning as the AI workflow platform for teams that need enterprise-grade controls.

◆ Prediction

The eval framework (currently beta) will likely gain deeper integration with CI/CD and deployment flows. Guest access metering signals that Windmill is building toward consumption-based pricing for external-facing AI apps. Expect tighter integration between the agent evals system and the existing flow editor deployment pipeline.
