How to install WAHA in 1 click on your VPS
WAHA (WhatsApp HTTP API) is the open-source WhatsApp API to connect chat to your automations and systems. Spin yours up with no terminal.
TL;DR
Install self-hosted WAHA in 1 click from the Rollin App Panel, with a free subdomain and automatic SSL. WAHA is an open-source WhatsApp HTTP API that connects WhatsApp to n8n, CRMs and your own systems via webhooks — an Evolution API alternative. It runs on the VPS Lite (AMD EPYC) from US$ 12.71/mo, flat monthly price with no lock-in, and anyone installs with no commands, with 24/7 human support on WhatsApp and Discord.
What is WAHA
WAHA (WhatsApp HTTP API) is an open-source project that turns WhatsApp into a simple HTTP API: you send and receive messages, media and events via REST requests and webhooks. It's the missing piece to connect WhatsApp to any system — CRM, ERP, n8n, bots and your own automations.
By hosting WAHA on your own VPS, you own the number and the conversation data, with no per-message platform fees. The App Panel handles the container and SSL automatically — you connect the number by QR code and get URL, token and webhook ready.
Runs well from the VPS Lite 10 (4 vCPU, 8 GB RAM). Each WhatsApp session uses memory — for several simultaneous sessions, move up to the Lite 20 or Lite 30.

Frequently asked questions
WAHA or Evolution API: which to install?
Both connect WhatsApp to automations and install in 1 click in the panel. Evolution API is widely used in Brazil with n8n; WAHA has a lean HTTP API and clear docs. You can try both — you only pay for the VPS. Our AI team helps you choose on WhatsApp or Discord.
Does WAHA integrate with n8n?
Yes. WAHA exposes webhooks and REST endpoints that n8n consumes directly — you build support, dispatch and integration flows without writing a backend. Installing WAHA + n8n in the same panel keeps everything on one server, fast and private.
How much does it cost to host WAHA?
WAHA is open-source and free to install — you only pay for the VPS. The VPS Lite starts at US$ 12.71/mo (4 vCPU AMD EPYC, 8 GB RAM, NVMe), flat monthly price with no lock-in, with local billing.
Do I need my own domain?
No. WAHA gets a free subdomain (yourapp.rollin-apps.store) with automatic SSL on install. Whenever you want, you connect your own domain from the same panel.
Do I need to know DevOps or Docker to install WAHA?
No — that's our differentiator. Anyone installs in 1 click, no commands at all: the panel handles the container, the database and SSL. And if you get stuck, 24/7 human support on WhatsApp and Discord jumps in with you.
