Can n8n replace Zapier? One user's $74/mo to $0 switch
The writer was paying Zapier $74 a month for 2,000 tasks and moved to self-hosted n8n on a server they already own. Their running workflows: RSS to Mattermost, starred Gmail to Todoist tasks, GitHub issues to Mattermost, a daily Docker-volume backup to Backblaze B2, a morning rain alert, and an error workflow that posts any failure to Mattermost.
Setup steps
- Run n8n with Docker Compose (one service, a data volume, port 5678)
- Open the editor and create an account
- Rebuild each Zap as a workflow: trigger node, then actions
- Add an Error Trigger workflow that posts failures to your chat
- Back up the data volume; it holds every workflow and credential

How it went
The writer replaced a $74/mo Zapier plan (2,000 tasks) and now runs feeds, task, issue, backup and weather workflows on n8n for $0 on their own server.
Worth knowing
Their dedicated error workflow, which posts the details of any failed run to Mattermost, has caught issues that would otherwise have gone unnoticed. SQLite is the default database and is fine for personal use.

Help me set up this automation using n8n (self-hosted, Docker) + Mattermost: "Can n8n replace Zapier? One user's $74/mo to $0 switch". Goal: replace Zapier. How it should work: - Trigger: RSS, Gmail, GitHub or a schedule fires - Then: n8n runs the matching workflow - Then: Posts to Mattermost, adds Todoist tasks or uploads a backup - Then: Any failure is posted to an alerts channel - Result: Zapier-style automations with no task cap Setup steps (summarized from the original source): 1. Run n8n with Docker Compose (one service, a data volume, port 5678) 2. Open the editor and create an account 3. Rebuild each Zap as a workflow: trigger node, then actions 4. Add an Error Trigger workflow that posts failures to your chat 5. Back up the data volume; it holds every workflow and credential Guide me one step at a time. Ask me for anything you need (accounts, sheet or channel names) before you start. Safety rules: - Build and test with sample data first, and show me a sample result before anything goes live. - Keep anything that goes to other people (emails, posts, replies, record updates) as drafts for my review until I say otherwise. - Never send, post, buy, pay, delete or change records without my approval. - Tell me about any cost (paid plans, API usage) before I'd incur it, and help me set a spending limit. - Keep API keys and passwords out of shared docs and chats. - Privacy: API credentials stay on your own server instead of passing through Zapier, per the writer.

Pros and cons
Pros
- No task limits
- Credentials stay on your server
- A whole setup moves by copying one data volume
Cons
- You run and update the server
- No AI step in these workflows; add one yourself if you need it
