Best open-source alternatives to Make (Integromat)

n8n is a workflow automation platform aimed at technical teams that want both low-code convenience and the flexibility to extend automations with code. It combines a visual interface with support for JavaScript, Python, and npm packages, making it suitable for users who need more control than typical no-code tools provide. The project is designed for self-hosted deployments as well as a hosted cloud offering. Its README emphasizes enterprise-oriented capabilities such as advanced permissions, SSO, and air-gapped deployments, alongside a large ecosystem of integrations, templates, and AI-native workflow building based on LangChain.

Huginn is a self-hosted automation platform for creating “agents” that observe online events and trigger actions. It is positioned as a hackable alternative to services like IFTTT or Zapier, with the emphasis on running on the user's own server so the user retains control of their data. The project is aimed at people who want to build personal or operational workflows around web monitoring, notifications, and event processing. The README describes examples such as tracking weather, scraping sites, watching Twitter terms, sending digest emails, handling webhooks, and chaining agent outputs into more complex automations. It also supports extending the system with external agent gems, making it suitable both for end users and developers who want to add custom integrations.

Kestra is an open-source orchestration platform for automating workflows that are either scheduled or triggered by events. It is designed for teams building data pipelines, process automation, and microservice orchestration, with a strong emphasis on Infrastructure as Code and declarative definitions. The project centers on YAML-based flows that can be created and edited from a web UI, then synced back to version control or managed via API and infrastructure tooling. Its plugin ecosystem lets users run scripts, query databases, interact with cloud services, and respond to events from many external systems, while the UI provides visualization and editing assistance for building and operating workflows.

Node-RED is a low-code development tool for building event-driven applications. It is aimed at developers and makers who want to wire together data sources, services, and logic visually rather than writing everything from scratch. The project is run as a Node.js application and can be started locally after installing it with npm. Its ecosystem includes a library of nodes, reusable flows, and collections, along with documentation and community support through the forum and Slack. The README also points to custom nodes and integrations, suggesting that the platform is designed to be extended and adapted to many automation and integration use cases.

Activepieces is an open source automation platform for building workflows and integrations, aimed at both technical and non-technical users. It presents itself as an extensible alternative to Zapier, with a no-code builder and a type-safe TypeScript pieces framework for creating custom integrations. The project emphasizes AI-first automation, community-contributed integrations, and self-hosted deployment for greater control and security. It also supports human-in-the-loop steps, input interfaces such as chat and forms, and publishing pieces as MCP servers for use with tools like Claude Desktop, Cursor, and Windsurf. The README also notes that the community edition is MIT licensed while enterprise features are covered by a commercial license.

Windmill is an open-source developer platform aimed at teams that need to build internal automation, APIs, background jobs, workflows, and user interfaces from code. It lets users write scripts in languages such as Python, TypeScript, Go, and Bash, then automatically turns script parameters into shareable UIs and combines scripts into flows or richer low-code apps. The project is self-hostable and positioned as an alternative to tools like Retool, Pipedream, Superblocks, and Temporal. It supports multiple triggers, local development workflows, and integrations for syncing code from GitHub or using a VS Code extension. The README emphasizes performance, sandboxing, and a Postgres-backed architecture, and notes that Windmill Labs also offers dedicated instances, commercial support, and licenses.

Automatisch is a business automation platform positioned as an open-source alternative to Zapier. It is aimed at users and businesses that want to connect cloud services and automate repetitive workflows without needing programming knowledge. The README emphasizes self-hosting and data ownership, making it suitable for organizations that need to keep sensitive information on their own servers for privacy, compliance, or vendor-lock-in concerns. It also points readers to documentation for additional installation methods beyond Docker Compose, and notes that the project is offered as both a Community Edition under AGPL and an Enterprise Edition under a commercial license.

Centaur is a self-hosted agent platform aimed at teams that want to centralize AI-assisted work instead of running many separate local setups. It connects to Slack and also exposes an API, letting users spawn an agent, send messages, and receive progress and final results while the platform manages sandbox assignment and execution. The system is built around Kubernetes-based sandboxes, durable state storage in Postgres, tool and workflow registries, and controlled outbound access through iron-proxy. It is designed for practical isolation and auditability, with support for shared tools, reusable workflows, credential injection without exposing raw secrets, and layered organization-specific customization.
