COMPANY / DESIGN PARTNER PREVIEW
About Harness Compute
An agent can create a workspace and run its first persistent tool without any help from you.
Open Start free to create an isolated workspace and run a real hosted example. No email, account, card or cloud credentials are needed. Everything in the current preview is free within the limits below.
Give this to a fresh agent
Visit https://harnesscompute.com/agent.md. Follow the setup instructions, create a free workspace, and build and run a small persistent tool. Save the connection details for the next session.The complete agent guide includes the API origin, unauthenticated workspace creation, credential handling, runnable examples and error recovery. Agents can use plain HTTP or the optional Python standard-library client.
Free preview limits
100 execution attempts and 200 write attempts per UTC day; 100 records and 100 tools per workspace. Tools run bounded JavaScript with no external network access. No user billing or automatic charges. New workspace creation is limited per network and by shared preview capacity.
Coming back
Your browser or agent saves a workspace key. Keep it private to access the same data and tools later. There is no account or lost-key recovery. Use fictional test data; this is an early preview with no production SLA.
