Activepieces vs Windmill

Activepieces

• Teams that want open-source automation they can host themselves
• Small teams that prefer a flat price to per-seat billing
• Building AI agents alongside trigger-and-action flows

Windmill

• Engineering teams that want internal tools and automations kept as code
• Organizations that must run workflows on their own infrastructure
• Replacing scattered cron jobs and scripts with one orchestrated platform

Activepieces

• The Free cloud plan covers a single user and 1,000 credits a month; runs beyond the quota do not go through until credits refresh.
• AI steps cost 2, 10 or 20 credits depending on the model. Connecting your own AI keys, on Plus and above, brings each AI step down to 1 credit.
• The self-hosted Community edition leaves out Agents and Chat and MCPs. SSO starts on Team, and SCIM and audit logs need Ultimate.
• Activepieces says its SOC 2 program is still in progress and that it does not yet hold the certification.

Windmill

• Windmill is code-first: scripts and most flow steps are written in a programming language, so it suits engineers more than non-technical users.
• The free self-hosted edition stops at 3 workspaces, 50 users and 10 SSO users, has no audit logs and keeps run details for up to 30 days.
• Cloud Free covers 1,000 executions a month, and an execution is one job of under a second; each extra second of compute counts as another.
• Enterprise and Pro bill at least 2 compute units, and their instances report seat and memory use to Windmill through license telemetry.

Activepieces

Flow builder

A visual builder with branching, retries, waitpoints, subflows, error handling and human approvals. TypeScript can be written inline for a step that needs code.

AI agents and chat

An agent takes a task described in plain words and chooses tools from connected apps and MCP servers, with approval gates on the steps you pick. Chat drafts flows from a description.

Pieces

The integration directory lists 762 pieces, all open source under the MIT license. An HTTP piece reaches any REST or GraphQL API that does not have a piece yet.

Tables and knowledge base

Tables hold data that every flow and agent can read and write, and a knowledge base makes your documents searchable by agents.

MCP server

Tools built in Activepieces can be served over MCP, so assistants such as Claude and Cursor can run them. MCPs are part of the cloud plans, not the Community edition.

Cloud, self-hosted or air-gapped

Activepieces Cloud runs in Frankfurt. The same software can be installed on your own infrastructure with Docker or Kubernetes, including with no outbound network.

Windmill

Scripts in more than 20 languages

A function in TypeScript, Python, Go, Rust, Bash, SQL, PHP or another supported language becomes an API endpoint and a form. Imports are resolved and versions locked at each deploy.

Workflows as a graph or as code

Flows are drawn in a flow editor or written in Python or TypeScript and called as an API endpoint. Retries, approval steps and parallel branches are built in.

Internal apps

An app is a React or Svelte frontend whose backend is your existing scripts and workflows. It can be shared with teams, published publicly or embedded in another product.

AI agents and AI-assisted building

Agents run on any of 12 model providers or your own OpenAI-compatible endpoint, with scripts and MCP servers as their tools. Scripts and flows can also be generated with AI in the UI.

Forks, review and rollback

Changes are made in a fork of the workspace, reviewed as a diff, then deployed to staging and production. Each deployment keeps its version, so an earlier one can be redeployed.

Run history and observability

Every run keeps its inputs, logs and result, and a failure can alert a team on Slack, Teams or by email. Enterprise adds audit logs, queue metrics and OpenTelemetry tracing.
