Self-Hosted Alternatives to Zapier

Why Replace Zapier?

Cost. Zapier’s free tier gives you 100 tasks/month — enough to test, not enough to use. The Starter plan is $29.99/month for 750 tasks. Professional is $73.50/month for 2,000 tasks. If you run dozens of automations with frequent triggers, costs escalate quickly to $200-500+/month.

Privacy. Every Zapier workflow routes your data through Zapier’s servers. Your API keys, email content, customer data, and internal documents all pass through a third party.

Limits. Zapier’s free and starter tiers have polling intervals of 15 minutes. Multi-step Zaps require paid plans. Premium apps (e.g., Salesforce) cost extra. The nickel-and-diming adds up.

Vendor lock-in. Your workflows exist only on Zapier’s platform. If they raise prices, change features, or go down, your automations stop. Self-hosted alternatives give you full ownership.

Best Alternatives

n8n — Best Overall Replacement

n8n is the closest thing to a self-hosted Zapier that actually works. It has 400+ built-in integrations, a visual canvas editor, JavaScript/Python code nodes, and error handling workflows. It handles complex multi-step automations that would require Zapier’s most expensive plan.

What makes it better than Zapier:

  • Unlimited tasks (no per-execution pricing)
  • 400+ integrations included
  • Code nodes for custom logic
  • Self-hosted — your data stays on your server
  • Error handling with dedicated error workflows

Trade-offs vs Zapier:

  • Requires a server and Docker setup
  • Learning curve for the canvas editor
  • Uses Sustainable Use License (not OSI open source)

Activepieces — Best Open-Source Alternative

Activepieces is the best choice if open-source licensing (MIT) matters to you. It has a clean step-by-step builder that’s the most Zapier-like of any self-hosted tool, 200+ integrations, and active weekly development.

What makes it compelling:

  • MIT license — truly open source, no restrictions
  • Most Zapier-like UI of any alternative
  • 200+ integrations and growing fast
  • Branches, loops, and code steps supported

Trade-offs vs n8n:

  • Fewer integrations (200+ vs 400+)
  • Younger project (since 2023)
  • Less advanced error handling

Node-RED — Best for IoT & Custom Flows

Node-RED isn’t a Zapier clone — it’s a flow-based programming tool. But if your automations involve IoT devices, MQTT, hardware, or custom data processing, Node-RED is unmatched. It has 4,000+ community nodes and runs on a Raspberry Pi.

Best for:

  • IoT and smart home automation
  • Real-time data processing
  • Developers who want maximum flexibility
  • Running on minimal hardware

Not ideal for:

  • Non-technical users (steeper learning curve)
  • SaaS-to-SaaS business automations (fewer pre-built connectors)

Windmill — Best for Developer Teams

Windmill is a code-first platform for scripts, workflows, and internal tools. If your “automations” are actually Python scripts, data pipelines, or internal tools, Windmill is purpose-built for this. It auto-generates UIs from script parameters.

Best for:

  • Developer teams writing scripts and data pipelines
  • Internal tool building with auto-generated UIs
  • Multi-language support (Python, TypeScript, Go, Bash, SQL)
  • Approval workflows with human-in-the-loop

Huginn — Best for Web Monitoring

Huginn is the original self-hosted automation tool (since 2013). Its strength is web monitoring — agents that watch websites, extract data, and trigger actions based on changes. Think “IFTTT for web scraping.”

Best for:

  • Price monitoring
  • Website change detection
  • RSS/news aggregation with filtering
  • Custom web scraping workflows

Caveat: Development has slowed (last tagged release: Aug 2022). For new projects, consider n8n or Activepieces instead.

Automatisch — Simplest Zapier Clone

Automatisch is the most faithful Zapier clone — simple trigger-action workflows with a familiar UI. However, with only ~40 integrations and slower development, it’s best suited for simple automations with major platforms.

Migration Guide

From Zapier to n8n

  1. Export your Zap list — document each Zap’s trigger, actions, and filters
  2. Recreate in n8n — most Zapier triggers have n8n equivalents:
    • Zapier Webhook → n8n Webhook node
    • Zapier Schedule → n8n Cron/Interval node
    • Zapier Filter → n8n IF node
    • Zapier Formatter → n8n Function/Code node
  3. Migrate credentials — create connections in n8n’s credential store
  4. Test thoroughly — run parallel for a week before disabling Zapier
  5. Cancel Zapier — once all workflows are running reliably on n8n

Break-even: A $7/month VPS running n8n with unlimited executions replaces a $74+/month Zapier Professional plan. The self-hosted option pays for itself in month one.

What You Give Up

  • Convenience. Zapier works out of the box — no server, no Docker, no maintenance. Self-hosting requires setup and occasional updates.
  • Integration breadth. Zapier has 7,000+ integrations. n8n has 400+, Activepieces 200+. Niche apps may not have connectors yet.
  • Uptime guarantees. Zapier provides 99.9% SLA. Self-hosted uptime depends on your infrastructure.
  • Mobile app. Zapier has iOS/Android apps for monitoring. Self-hosted tools are web-only.
  • Support. Zapier has paid support tiers. Self-hosted tools rely on community forums and documentation.

For most self-hosters, the cost savings and data ownership far outweigh these trade-offs.
