What is Langfuse?

Langfuse promotes Experiments out from under Datasets, making evaluation the primary workflow.

Langfuse's recent work is concentrated almost entirely on the evaluation surface. Experiments were rebuilt as a top-level feature that runs with or without a dataset attached, and can be compared across runs over time. The LLM-as-a-Judge evaluator gained categorical scores in late March and boolean true/false scores a week later, filling out the score types beyond plain numerics. Everything else in the window is documentation or scrape artifacts.

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.

Langfuse promotes Experiments out from under Datasets, making evaluation the primary workflow.

◆ Current state

Langfuse's recent work is concentrated almost entirely on the evaluation surface. Experiments were rebuilt as a top-level feature that runs with or without a dataset attached, and can be compared across runs over time. The LLM-as-a-Judge evaluator gained categorical scores in late March and boolean true/false scores a week later, filling out the score types beyond plain numerics. Everything else in the window is documentation or scrape artifacts.

◆ Where it's heading

The direction is evaluation as the product's centre of gravity rather than an appendage to tracing. Decoupling Experiments from Datasets removes the setup cost of running an eval, and the widening score types let judges express verdicts rather than only magnitudes — both point at teams running evals continuously against live traces instead of curated fixtures. Regional expansion shows up in the feed as Langfuse Cloud Japan. Cadence is the open question: nothing has published since April 21, so this arc is described from a three-month-old window.

◆ Prediction

The score-type buildout and the run-comparison view are converging on scheduled or triggered evaluations against production traces, but the feed has been silent long enough that the next move cannot be called with confidence from these entries alone.

5.0

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.
