What are the best alternatives to n8n for self-hosted automation?

Quick Answer: The strongest self-hosted alternatives to n8n as of July 2026 are ActivePieces (MIT-core licence, 700+ pieces), Windmill (AGPLv3, code-first across 12 languages), and Kestra (Apache 2.0, engineering-grade orchestration). Huginn (MIT, 49,000+ stars) remains a proven agent-based option, and Trigger.dev covers code-first TypeScript jobs. Automatisch is no longer recommended without caveats: its hosted cloud shut down and repository activity stalled in January 2026.

Best Self-Hosted Alternatives to n8n

n8n is the most widely deployed self-hosted automation platform (196,000+ GitHub stars as of July 2026), licensed under its fair-code Sustainable Use License — free for internal business use, with enterprise features under a paid licence. It is not the only option. Teams that need a more permissive licence, a code-first model, or a different automation paradigm have several actively maintained alternatives; the licence, connector count, and maintenance figures below were verified 14 July 2026.

ActivePieces: Closest to the n8n Experience

ActivePieces provides a visual workflow builder similar to n8n's with a clean interface that non-technical users find approachable. The core is MIT-licensed (enterprise features under packages/ee/ carry a commercial licence), and the official catalog lists 755 pieces as of July 2026 — the project promotes "700+ integrations", a large share community-contributed, and its open-source pieces double as MCP servers for AI-agent use (the official MCP catalog lists 700+).

  • License: MIT core (Community Edition); commercial licence for ee/ enterprise features
  • Deployment: Docker and Docker Compose
  • Integrations: 700+ pieces (755 listed in the official catalog, July 2026)
  • Activity: 23,000+ GitHub stars, commits daily as of July 2026
  • Best for: Teams wanting n8n-like visual building with an MIT-core licence

Windmill: Code-First Multi-Language Platform

Windmill puts code first: scripts become workflows, UIs, and scheduled jobs. Language coverage has expanded well beyond its original set and now spans Python, TypeScript (Bun/Deno), Go, Bash, SQL, GraphQL, PowerShell, Rust, PHP, C#, Java, and Ansible as of July 2026.

  • License: AGPLv3 (client libraries Apache 2.0; enterprise-flag code proprietary)
  • Deployment: Docker and Kubernetes with production-ready configurations
  • Languages: 12 supported, from Python and TypeScript through Rust, Java, and Ansible
  • Activity: 17,000+ GitHub stars, commits daily as of July 2026
  • Best for: Developer teams who prefer writing code over dragging nodes

Kestra: Engineering-Grade Orchestration

Kestra has grown into one of the most active open-source orchestrators (Apache 2.0, 27,000+ GitHub stars as of July 2026). Workflows are declared in YAML and triggered by events or schedules, with installation via Docker, Docker Compose, Kubernetes/Helm, or a standalone JAR. It sits closer to Airflow-style data and infrastructure orchestration than to Zapier-style app connecting — the right fit when workflows are owned by an engineering team.

  • License: Apache 2.0
  • Deployment: Docker, Docker Compose, Kubernetes/Helm, standalone JAR (2 vCPU / 4 GiB minimum)
  • Model: Declarative YAML flows, event-driven triggers, plugin ecosystem
  • Best for: Engineering-led automation and data/infrastructure orchestration

Huginn: Agent-Based Monitoring and Automation

Huginn is the original self-hosted automation tool, predating n8n by years. Specialized agents monitor websites, process data, and trigger actions, connected in directed graphs. It remains maintained (last commit July 2026) as a community-run Ruby on Rails project with modest velocity rather than a commercial product.

  • License: MIT
  • Deployment: Docker, Heroku, or manual Ruby on Rails installation
  • GitHub Stars: 49,000+ (July 2026)
  • Best for: Developers wanting an agent-based system for web monitoring and event processing

Trigger.dev: Code-First TypeScript Jobs

Trigger.dev (Apache 2.0, 15,000+ stars) targets TypeScript teams building background jobs, durable workflows, and AI agents in code. Official self-hosting guides cover Docker Compose and Kubernetes. It is not a visual no-code builder; it competes with n8n only where the team is happy writing TypeScript.

  • License: Apache 2.0
  • Deployment: Self-hosted via Docker Compose or Kubernetes, or managed cloud
  • Best for: TypeScript teams replacing queue infrastructure rather than visual workflows

Automatisch: Caution Advised as of 2026

Automatisch offers a Zapier-style trigger-and-action model under AGPL-3.0 (with .ee. files under an enterprise licence) and ships 92 app integrations in its repository (about 79 external-service connectors plus built-in utilities, July 2026). However, its hosted cloud was shut down (registration disabled and a shutdown alert added in December 2025) and the repository has had no meaningful commits since January 2026. Self-hosting still works, but teams should treat it as unmaintained until activity resumes.

  • License: AGPL-3.0 with enterprise-file exceptions
  • Status: Cloud discontinued; development stalled since January 2026
  • Integrations: 92 apps in-repo (July 2026)
  • Best for: Only teams comfortable adopting a currently dormant project

Comparison Table

Tool License Approach Integrations / Languages Activity (Jul 2026) Best For
ActivePieces MIT core Visual builder 700+ pieces Very active n8n-like experience, permissive core
Windmill AGPLv3 Code-first 12 languages Very active Developer teams
Kestra Apache 2.0 Declarative YAML Plugin ecosystem Very active Data/infra orchestration
Huginn MIT Agent-based Agent graph Maintained (community) Web monitoring
Trigger.dev Apache 2.0 Code-first (TS) SDK-based Very active TypeScript background jobs
Automatisch AGPL-3.0 Trigger-action 92 apps Stalled since Jan 2026 Not currently recommended

Choosing Among Them

Teams wanting the closest visual experience to n8n with a permissive core licence should evaluate ActivePieces first. Engineering-heavy teams that prefer code get the broadest language coverage from Windmill, declarative orchestration from Kestra, or TypeScript-native jobs from Trigger.dev. Huginn remains dependable for agent-style web monitoring. Automatisch, previously an easy recommendation for simple setups, carries maintenance risk until its development resumes.

Best Human-in-the-Loop Automation Platforms 2026

Eight platforms are ranked here on a single mechanism: how a person enters an automated path, and what the system can prove afterward about the decision they made. Moxo scores 7.7 and ranks first; Camunda 8 scores 7.2, Microsoft Power Automate 7.1, Pega 6.9, n8n 6.7, Zapier 5.9, Kissflow 5.8 and ServiceNow 4.8, scored 22 September 2026 on the five weighted criteria. Those criteria cover the step type, the approver's account or licence, the routes available on a rejection, the audit record, and the meter that charges for the decision, and none of them can tell a review from a rubber stamp, so the methodology adds a check readers can run on any product in a few minutes: whether the decision record tells a considered approval from an instant one. Every figure was read from a vendor-owned surface and carries its own date.

Best Automation Platforms for AI Orchestration 2026

This ranking answers one question: how many real business applications can an AI agent act on out of the box? It evaluates nine platforms as of August 2026 on the reach they give an agent, not on the workflow logic they can express. That boundary is deliberate, because two neighbouring pages on this site answer different questions. Best Process Orchestration Platforms 2026 scores multi-step process control, error handling and state management. Best AI Agent Platforms 2026 scores building and hosting the agent itself. This page scores the layer between them: the connective tissue that lets an agent already built elsewhere reach the applications a business actually runs on. A platform that leads one of those pages can place low here, and two of them do. Scores derive from application and action catalogue counts, the exposure model each platform uses to publish those catalogues to an agent, setup effort, failure handling and cost per agent action. Every figure was retrieved from a vendor-owned surface on 11 August 2026 unless an earlier date is stated against it.

Moxo vs Lindy in 2026: Who Presses Approve When the Agent Asks

Lindy, founded in 2023, sells an AI teammate that lives in Slack and in each person's inbox; Moxo, whose predecessor Moxtra was co-founded in 2012, runs multi-party processes where approvals are steps only a person can close. Moxo wins three rounds to two: who closes the step, work across companies and the record. Lindy wins reach and testing. Vendor pages and docs read 28 September 2026.

comparison

Moxo vs Kissflow in 2026: What an Outside Approver Costs, and What the Record Proves

Moxo and Kissflow both sell approvals to people who do not write code, and each wins one round outright: Moxo's Web and Headless SDKs run the approval inside the buyer's own product, under the buyer's own sign-in. Kissflow's portal audit log stamps every event with an actor, a device and an IP, where Moxo publishes no field list. Both answers are quoted, not priced, and both meters punish a one-step request sent to hundreds of clients. Cost, the decision record, rejection routes, AI metering and governance, verified 14 to 23 September 2026.

Moxo vs Camunda 8 in 2026: BPMN User Tasks for Staff, Step Types for Outsiders

Camunda 8 can fix a process under cases already running, since active instances migrate onto a corrected definition and, for Camunda user tasks, "a migrated active user task remains assigned to the same user". Moxo keeps the shared queue that Camunda's Tasklist V2 stops evaluating, with desks that are "a shared inbox that multiple users can pick work from". Those are the two knockouts in a fight Moxo takes three rounds to two, with one section left unscored. Portability, AI review gates and a published price decide the rest, verified 14 to 23 September 2026.
