Serverless functions

Functions let you run small snippets of code without managing a long-running service — triggered over HTTP or on a cron schedule. Supported runtimes: Python, Node, Deno, and Bun.

From the dashboard

1. Open your project and go to the Functions panel.
2. Click New function and give it a name.
3. Pick a runtime and paste (or write) your code.
4. Choose a trigger — HTTP (get an endpoint to call) or Cron (set a schedule).
5. Optionally set a timeout and memory limit, then save.

The Functions panel opens from the toolbar at the bottom of the project canvas.

Invoke it from the panel, and view recent runs — status, duration, and output — in its invocation history. HTTP-triggered functions also expose an endpoint path you can call directly.

From the CLI

# Inline code, or from a file:
bitsreef functions create my-project hello --runtime python --code 'print("hi")'
bitsreef functions create my-project hello -r node -f ./handler.js --trigger cron --cron "0 * * * *"

bitsreef functions invoke my-project <function-id>
bitsreef functions history my-project <function-id>
bitsreef functions update my-project <function-id> --file ./handler.js
bitsreef functions delete my-project <function-id>

Functions vs. services

Reach for a function for event-driven or scheduled snippets. Reach for a service when you need a long-running process, a full web server, or a custom container image.
