What is Windmill?

Windmill hardens its runtime: daemonless containers, SSH execution, dev/prod workspaces.

Windmill is an open-source developer platform that runs scripts, flows, and apps as a workflow and internal-tools engine. Its changelog is a genuine, dense stream of runtime and operations features. The current cluster centers on execution flexibility (containers, remote SSH, SQL S3 inputs), environment safety (dev/prod workspaces), and enterprise observability and governance (OTEL tracing, audit-log export, Kubernetes autoscaling).

What is ToolJet?

ToolJet widens its data-source layer — AI sources included — on a fast LTS/beta release train.

ToolJet, the open-source low-code app builder, runs a fast dual-track release train: a 3.20.x LTS line and a 3.21.x beta line. Recent work centers on data-source breadth (native AI/OpenAI-OpenAPI sources, a DynamoDB overhaul, Databricks, MS Graph, Snowflake fixes), query-runner features (abort, execution metadata), Git-sync hardening, and a steady stream of widget and permission fixes.

Windmill vs ToolJet: editorial side-by-side

6.3

Windmill hardens its runtime: daemonless containers, SSH execution, dev/prod workspaces.

◆ Current state

Windmill is an open-source developer platform that runs scripts, flows, and apps as a workflow and internal-tools engine. Its changelog is a genuine, dense stream of runtime and operations features. The current cluster centers on execution flexibility (containers, remote SSH, SQL S3 inputs), environment safety (dev/prod workspaces), and enterprise observability and governance (OTEL tracing, audit-log export, Kubernetes autoscaling).

◆ Where it's heading

Windmill is maturing along two tracks at once: a more capable, safer execution runtime (sandboxed multi-tenant containers without a Docker daemon, remote SSH targets) and the enterprise scaffolding around it (environment promotion, distributed tracing, audit export, smarter K8s scale-in). The direction is making the platform safe to run untrusted, multi-tenant code at scale while giving teams real dev/prod discipline.

◆ Prediction

Expect continued investment in isolation/runtime breadth and enterprise operability — more sandboxing options, deeper observability, and workspace/promotion tooling. The cadence is fast and consistent, with the daemonless container runtime the most likely lever for new multi-tenant and cloud use cases.

5.0

ToolJet widens its data-source layer — AI sources included — on a fast LTS/beta release train.

◆ Current state

ToolJet, the open-source low-code app builder, runs a fast dual-track release train: a 3.20.x LTS line and a 3.21.x beta line. Recent work centers on data-source breadth (native AI/OpenAI-OpenAPI sources, a DynamoDB overhaul, Databricks, MS Graph, Snowflake fixes), query-runner features (abort, execution metadata), Git-sync hardening, and a steady stream of widget and permission fixes.

◆ Where it's heading

The direction is a broader, more enterprise-ready connector layer with AI data sources moving in natively, plus maturing Git-sync workflows (cross-branch conflict detection, leakage fixes) for team development. Betas front-run the LTS line, so features like AI/OpenAPI data sources and query abort graduate from 3.21-beta into 3.20-lts. Expect continued connector expansion and versioning polish.

◆ Prediction

Next releases will likely keep widening data-source coverage — more AI-native and cloud sources — and hardening Git-sync team workflows, with beta features flowing into the LTS line.
