Runs 2.0 — human-in-the-loop approvals, built in
Hire agents that
actually finish.
Kestrel turns your SOPs into AI agents that read the inbox, call your tools and close the loop — every step traced, priced, and paused for your approval when it matters.
No card · SOC 2 Type II · Self-host ready

How it works
From SOP to shipped
in an afternoon.
Step 01
Describe the job
Paste your SOP or talk it through. Kestrel turns plain language into a typed plan you can read, diff and version.
Step 02
Connect your tools
One-click OAuth for 200+ apps, or point it at any API. Every agent gets only the scopes its job needs.
Step 03
Approve, then it ships
Set the line — dollars, recipients, data. Under it, agents run solo. Over it, you get a one-tap approval in Slack.
02
The platform
Built for agents you can
actually trust.
Every step, on the record
Full traces of every tool call, token and dollar. Replay any run, diff two versions, export to your warehouse.
Evals gate every deploy
Version 15 doesn’t ship until it beats version 14 on your own test set.
Budgets that hold
Cap spend per agent, per run or per month. Hit the line and it stops — no surprise invoices.
Grounded in your docs
Point agents at drives, wikis and tables. Answers cite the exact source, or they don’t answer.
Your cloud or ours
Run fully managed, or deploy into your own VPC with keys in your KMS. SOC 2 Type II and GDPR ready.

From the field
“We tried three agent frameworks. Kestrel is the first one finance actually lets near the money — every payment is traced, capped and approved.”

Which models does Kestrel use?
