Used For

• +**Your founder spends 30 minutes daily checking for real signups mixed with test accounts** → Activepieces filters test emails automatically and sends Slack alerts only for real users
• +**You're paying for 6 micro-SaaS tools just to generate QR codes and extract PDF text** → Build custom pieces using npm libraries in under 30 minutes, replace the whole stack
• +**Your AI agents are limited by crappy integrations in other platforms** → 400+ pre-built pieces plus the ability to package multi-step flows as single AI tools
• +Builds TypeScript integrations in 30 minutes - no waiting for vendors to support your niche CRM
• +Self-hosting removes all task limits - run 100,000 automations monthly without subscription increases

Best For

• >Your team manually checks dashboards and copies data between 5 different tools
• >You're hitting Zapier's task limits and the bill is getting stupid
• >Small agency managing client automations without paying per sub-account

Not For

• -Large enterprises wanting fully managed cloud with unlimited tasks — you'll need to self-host or hit subscription caps
• -Pure no-code teams who panic at the sight of TypeScript — custom pieces require some dev comfort
• -Solo users doing 50 tasks monthly — you're not hitting enough volume to see value over simpler tools

Pairs With

• *Slack (where your team gets instant notifications about new signups instead of checking dashboards)
• *Google Sheets (to log filtered data automatically instead of manual copy-paste sessions)
• *Supabase (triggers flows when new users sign up or data changes)
• *HubSpot (gets updated automatically when deals progress, no sales rep data entry)
• *Stripe (triggers onboarding flows when payments succeed)
• *PostgreSQL (stores automation results and triggers database-driven workflows)
• *Node.js (runs your custom TypeScript pieces when the 400+ pre-built ones aren't enough)

The Catch

• !The 1,000 free tasks actually cover most startups, but growth companies hit limits fast without self-hosting
• !AI agents need approval steps for production use — they'll confidently do the wrong thing if you don't add guardrails
• !Community contributes 60% of the pieces, so popular integrations appear fast but niche ones might need custom building

Bottom Line

Open-source Zapier that won't bankrupt you at scale — unlimited tasks if you self-host, or 1,000 free monthly tasks that most startups won't hit.
