How much RAM does Activepieces need?

The stack (app + PostgreSQL + Redis) uses about 1.5 GB at idle. Plan for 2 GB minimum; 4 GB is comfortable for production with dozens of active flows and concurrent executions.

Why is AP_FRONTEND_URL critical?

Activepieces embeds this URL in every webhook it generates. If it points to localhost or an internal address, external services (GitHub, Stripe, WhatsApp…) cannot reach your webhook endpoints. Always set it to your public HTTPS domain before creating flows.

Is Activepieces compatible with n8n flows?

Activepieces and n8n are not directly import-compatible — they use different flow formats. However, most n8n workflows can be recreated in Activepieces in minutes using equivalent pieces. Both cover the same integrations; the choice is about the visual builder you prefer.

What are MCP servers in Activepieces?

MCP (Model Context Protocol) servers expose tools — web search, code execution, browser automation, file access — that AI models can call during a flow step. Activepieces ships with 400+ MCP server integrations, letting you build AI agent workflows without a separate orchestration layer.

Can I migrate from Zapier to Activepieces?

Yes. Activepieces covers most Zapier integrations via its 280+ pieces. Start by listing your active Zaps, then recreate them one by one in Activepieces — the visual builder is similar enough that the mapping is direct. Run both in parallel for a week before cancelling Zapier.

Activepieces is an MIT-licensed workflow automation platform that replaces Zapier and Make on your own infrastructure. With 280+ integrations (pieces), a visual flow builder, and built-in support for AI agents and 400+ MCP servers, it covers everything from simple webhook-to-Slack pipelines to multi-step AI agentic workflows — all without usage-based billing.

Deployed on a ServOrbit VPS, Activepieces runs on a single Docker Compose stack (app + PostgreSQL + Redis). Your automation credentials, webhook payloads, and flow logic stay on your server. At a fixed monthly VPS cost, you can run thousands of automations that would cost hundreds of dollars on cloud platforms.

Key features

280+ connectors (pieces) — Slack, Gmail, HubSpot, Notion, WhatsApp, MySQL, HTTP…

Visual flow builder with branches, loops, filters, and custom code steps in TypeScript

AI agent automation: 400+ MCP servers wired to your flows as native steps

Webhook receiver with a stable URL on your domain — no ngrok tunnels needed

Sandboxed code execution — run custom TypeScript steps safely in isolation

Unlimited flows and executions at a fixed VPS cost — no per-task billing

MIT-licensed core, self-hosted data, version-pinned updates under your control

When to use this solution?

1

Agency automation hub

Run client automation flows on your VPS instead of paying per-task. Handle webhook ingestion, CRM syncs, and WhatsApp notifications for every client at a flat monthly cost.

2

AI agentic workflows

Wire MCP servers (browser automation, code runners, web search) into your flows. Build reliable multi-step AI agents without writing a dedicated backend.

3

Replacing Zapier / Make

Migrate your existing automations flow by flow. Each of the 280+ pieces maps directly to a Zapier app or Make module — no rebuild from scratch.

Deploy Activepieces on your VPS

Guide optimized for ServOrbit Cloud VPS.

01

Create the VPS

Order a ServOrbit VPS with at least 2 vCPU and 4 GB RAM. Ubuntu 22.04 LTS is the recommended OS. You will need a domain name (e.g. flows.yourdomain.ma) pointing to the VPS — Activepieces needs a public HTTPS URL to receive webhooks.

02

Deploy the stack

SSH into the VPS. Create /opt/activepieces/.env with your database credentials and two 32-character hex secrets (openssl rand -hex 16 twice for AP_ENCRYPTION_KEY and AP_JWT_SECRET). Run docker compose up -d — the app, PostgreSQL, and Redis start together.

03

Set AP_FRONTEND_URL (critical)

Add AP_FRONTEND_URL=https://flows.yourdomain.ma to your .env. This URL is embedded in every webhook Activepieces generates — if it's wrong, incoming webhooks will miss your instance. Restart after any change to this variable.

04

Put HTTPS in front

Install Caddy: apt install -y caddy. Create /etc/caddy/Caddyfile with: flows.yourdomain.ma { reverse_proxy localhost:8080 }. Caddy fetches a Let's Encrypt certificate automatically. Activepieces' webhook URLs will now be publicly reachable.

05

Create your first flow

Open https://flows.yourdomain.ma, create your admin account, then build a flow. Start with the Webhook trigger and connect a Slack or email step to validate your public URL. Check Settings → Connections to add your first integration credentials.

Frequently asked questions
