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 runs two release trains at once, and neither has changed direction in months

ToolJet ships an LTS line (3.20.x) and a beta line (3.21.x) in parallel, often several tags a week. The LTS train is almost entirely fixes, CVE patches and submodule chores; the beta train carries the actual features. The one substantial drop in this window is 3.21.57-beta, which added datasource tagging and mentions, AI integrations for HubSpot, ServiceNow and QuickBooks, and link and password expiry controls.

Langfuse vs ToolJet: editorial side-by-side

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.

ToolJet runs two release trains at once, and neither has changed direction in months

◆ Current state

ToolJet ships an LTS line (3.20.x) and a beta line (3.21.x) in parallel, often several tags a week. The LTS train is almost entirely fixes, CVE patches and submodule chores; the beta train carries the actual features. The one substantial drop in this window is 3.21.57-beta, which added datasource tagging and mentions, AI integrations for HubSpot, ServiceNow and QuickBooks, and link and password expiry controls.

◆ Where it's heading

The split is doing what it should: enterprises on LTS get security patches and module fixes, while feature work accumulates on beta before promotion. Most of the recent effort has gone into modules, expression resolution and component rendering — paying down the app-builder core rather than expanding it. The AI work is being wired into datasources rather than surfaced as its own product.

◆ Prediction

The 3.21 beta features should reach the LTS line once the module and expression fixes settle, and the AI datasource integrations look likely to widen beyond the first three connectors.
