Computer-use infrastructure, made usable
Turn the software your customers use into an API.
Celesto turns workflows inside browser portals, desktop applications, and legacy software into APIs that AI agents can reliably call.

How it works
The last mile lives in software you don’t control.
Portals, desktop apps, files, and authentication become one callable workflow.
- 01
Demonstrate
Show the task as it happens.
- 02
Add logic
Add code, rules, and approvals.
- 03
Call as an API
Trigger it and receive structured results.
First proving ground: logistics
One workflow, across every surface it touches.
A booking update can span a portal, files, business logic, and validation.
Example workflow

- 01Open carrier portalBrowser

Reliability layer
Computer use that survives the real world.
When software changes, Celesto retries, pauses, hands off, and resumes.
- Retries with context
- Checkpoint recovery
- Human takeover
- Observable outputs
