Compare Chrome extensions: Heartbeat vs WA Self Sender - Free Messages Sender

Heartbeat transforms REST endpoints into streaming APIs so you don't need to poll APIs periodically. Build for the #realtimeweb.

Key Features:

1. Convert any REST API into a streaming API with zero lines of code,
2. Access streams via a GUI dashboard, JS or REST APIs,
3. Optionally, store results for up to 6 hours and run advanced search queries on the stream via appbase.io's APIs.

It's free to use while in beta.

Technical notes:

• Heartbeat uses websockets as the underlying protocol so the resulting streaming APIs work well both on browsers and on other languages.
• Currently works with REST APIs that return JSON responses on either GET or POST requests, supports Basic Auth, custom headers.
