The hosted alternative to running your own WhatsApp library.
Baileys, whatsapp-web.js, and whatsmeow are great projects, but you still have to host them, patch them, and keep sessions alive. 2Chat gives you the same QR-based connection as a managed REST API, so you ship features instead of babysitting infrastructure.
What teams value when they consider
2Chat over Self-hosted libraries
Most teams that switch to 2Chat share a similar experience. These are the reasons they mention most often:
Your server becomes a full-time job
Running a library means a VPS, a process manager, session storage, reconnection logic, and monitoring. When the connection drops at 3 AM on a Sunday, restoring it is on you.
Breaking changes arrive without notice
These libraries reverse engineer the WhatsApp Web protocol. When WhatsApp ships a change, messaging can stop until maintainers publish a fix and you update and redeploy. Your roadmap pauses while you catch up.
Everything above the socket is still yours to build
A library gives you send and receive. An inbox for your team, contact management, automation flows, transcription, and campaign tooling are all custom code you have to write and maintain.

What you get with 2Chat that Self-hosted libraries does not give you
A hosted API with the same QR connection
Connect any WhatsApp or WhatsApp Business number by scanning a QR code, exactly like the libraries do, then send and receive over a REST API and webhooks. No WebSocket handling, no headless browsers, no session files.
Zero maintenance windows
2Chat absorbs protocol changes, keeps sessions alive, reconnects automatically, and scales the infrastructure. You never redeploy because WhatsApp changed something upstream.
A full platform when you need more than an API
Shared team inbox, no-code flow builder, AI agents, audio transcription, bulk messaging, a WhatsApp Groups API, and an MCP server. Use the API alone or hand the inbox to your team without writing a frontend.
An official path when you are ready
Unofficial libraries have no route to the official WhatsApp Business API. 2Chat supports verified WABA numbers through Meta Embedded Signup on the same platform, so you can start with a QR connection and upgrade without switching vendors.
Send your first API message in 5 minutes
Scan a QR code, grab an API key, and call the REST endpoint. No credit card required.

Which one is right for you?
A practical guide to evaluate why 2Chat is the right fit for you.
2Chat
2Chat is the better choice if you:
Want to ship a WhatsApp feature this week, not build infrastructure
Prefer a REST API and webhooks over managing WebSocket sessions
Need messaging to keep working when WhatsApp changes its protocol
Want a team inbox, flows, and AI on top of the same connection
Plan to move to the official WhatsApp Business API eventually
Self-hosted libraries
A self-hosted library is the better choice if you:
Need full protocol-level control and custom low-level behavior
Have the infrastructure and engineers to run and monitor it
Cannot route conversation data through a third-party platform
Are building an experiment or internal tool where downtime is acceptable
Switch to 2Chat without wasting time
No credit card required. Our team helps you migrate.
Start free trialConnect your number with a QR scan
Log out of your library's session so the linked-device slot is free, then scan the QR code in 2Chat. The connection works like WhatsApp Web, so your phone keeps working normally.
Grab an API key and send a test message
Generate a key from the dashboard and try the REST API or the Postman collection. Sending your first message is a single HTTP call.
Point your code at 2Chat endpoints
Replace library calls with HTTP requests to send messages, verify numbers, and manage groups. Register a webhook URL to receive inbound messages as JSON.
Retire your server
Shut down the VPS, the process manager, and the session storage. 2Chat keeps the connection alive and delivers every inbound message to your webhook.
Real-life experiences
Companies that transformed
Creating chatbots was super easy with their flow builder. Just drag and drop the components and it's ready in seconds. The connection to WhatsApp was also great. We used our own number without changing it to WhatsApp Business API.

2Chat has become an essential component of our daily operations! It was so nice to set up bots with their canvas for WhatsApp, in ten minutes we had an entirely new way to respond to our creators. Great integrations with Slack and Zapier!

2Chat's integration with Make.com is incredibly smooth and reliable. I've been using it to sync WhatsApp messages into Slack channels, and it works perfectly to keep everyone aligned without switching tools.
Wil M.
This tool allows you to use normal WhatsApp Business like an API, which opens many doors for automation. Customer support is very friendly. They have native integration with Zapier and Make. What you can ask more!

Frequently asked questions
How is 2Chat different from Baileys, whatsapp-web.js, or whatsmeow?
Those projects are libraries you embed in your own code and host on your own servers. 2Chat is a hosted platform: the connection to WhatsApp uses the same QR-based approach, but 2Chat runs it for you and exposes a REST API and webhooks. You do not manage sessions, reconnections, protocol updates, or infrastructure.
The libraries are free. Why would I pay for 2Chat?
The library is free, but running it is not: you pay for servers, session storage, and, above all, engineering time every time WhatsApp changes something or a session drops. 2Chat replaces that operational cost with a flat monthly fee and a team whose job is keeping the connection alive.
Can I connect the number I am using with my library today?
Yes. Log out of the library's session to free the linked-device slot, then scan the QR code in 2Chat. Your phone keeps working normally, just like with WhatsApp Web.
What happens when WhatsApp changes its protocol?
2Chat absorbs the change on its side. You do not need to update a dependency, wait for a maintainer to publish a fix, or redeploy anything. Your integration keeps calling the same REST endpoints.
Do I need a WhatsApp Business API (WABA) account?
No. The QR-based connection works with a regular WhatsApp or WhatsApp Business app number. When you are ready for the official API, 2Chat also supports verified WABA numbers through Meta Embedded Signup on the same platform.
Is automating a regular WhatsApp number allowed by WhatsApp?
Automating a regular number through the WhatsApp Web protocol is not officially supported by WhatsApp, and that applies to any tool, including open-source libraries. For use cases that require full compliance, 2Chat offers the official WhatsApp Business API on every plan, so you can move to a verified number whenever you need to.
