Automate Anything with Doppelganger + n8n

Hey n8n community! :waving_hand:

Full transparency: I made Doppelganger, and I want to share how you can automate anything — even tasks without APIs — using n8n via the official Doppelganger node.

What Is Doppelganger?

Doppelganger is a self-hosted browser automation platform that lets you visually create tasks and workflows you can run locally or on a server.

  • Automate repetitive browser tasks like clicks, form fills, and scraping.
  • Work with sites or tools that don’t have APIs.
  • Expose tasks via a secure API, which you can call from n8n.

Tips for Using Doppelganger with n8n

  1. Install the Official Node

    • Add the Doppelganger community node in n8n to call tasks directly from your workflows.

  2. Start Small

    • Test simple tasks like filling a form, scraping a page, or clicking buttons before combining multiple tasks.

  3. Prepare Your Data

    • Use Set or Function nodes in n8n to structure inputs before sending them to Doppelganger.

  4. Debug & Inspect Outputs

    • Check execution logs in n8n to confirm task results.
    • Add error-handling paths to capture failures gracefully.

  5. Chain Further Actions

    • Feed results to other nodes (databases, Slack, Email, etc.) to build full automation pipelines.

Example Mini Workflow

  1. Trigger (Webhook / Cron)
  2. Prepare Data (Set / Function node)
  3. Doppelganger Node (run task via API)
  4. Post-Process (Store results / notify / branch)

With this setup, you can truly automate anything — API or no API — using Doppelganger + n8n.
