### Open Source

Sunnyday runs on Axle, our open-source agent engine. The code that executes your tasks is public, not a black box: read it, run it, build on it.

[View on GitHub](https://github.com/johncch/axle)

### By people who care

Twenty years of shipping software, one current obsession: agents that work every time, not just in the demo.

[Behind the scenes](https://fifthrevision.com/writing/2026/why-im-building-sunnyday.html)

## Everything an Agent needs

### Build

From idea to working agent in one sitting

-   Write it like a brief, get a working agent
-   Shape it in the workbench until it nails the job
-   Add variables so one agent handles a hundred cases
-   Every change is versioned, so experiment without fear
-   Feed it your files and it works like it's read them

### Run

Real work needs a real computer

-   Every task gets its own fresh computer, not a chat window
-   It plans first, checks its work, and retries until it's right
-   Delivers real files: PDFs, Word docs, spreadsheets
-   Show it anything — it reads images and documents
-   Watch it think live, and jump in when you have notes

### Ship

Wire it in and walk away

-   Fire it from your app, a schedule, or a single click
-   Every run graded pass, partial, or fail. No silent failures
-   Full transcripts, for when you want receipts
-   See what every run costs, down to the token
-   Point it at GitHub and it runs on push, tag, or PR
