Everything you need to run a verified environment
Promigence is a sandbox platform for AI agents: production-grade, fully isolated sandboxes that start in milliseconds, stay fast at a thousand at once, and bill by the second.
$ npm i -g ./promigence-<version>.tgz # the file we sent you; not on npm yet
$ promigence signup # asks for your invite code
$ promigence run --snapshot promigence/base --count 2 --cap 1 --json -- python3 -c 'print(6*7)'
Quickstart
From the file you were sent to a verified snapshot and a 20-sandbox run.
CLI reference
Every command, and every flag it matters to know.
TypeScript SDK
The native client, and a compatibility Sandbox class so most existing sandbox code keeps working.
Errors and exit codes
What each failure means, whether it was billed, and whether it was yours or ours.
If you are an AI agent reading this
Run promigence agent-guide. It prints a ~1,200-token guide written for you rather than for a human: the command surface, the error codes, and the cost model. --install writes it into AGENTS.md, CLAUDE.md or .cursor/rules.
Plain-text sources for machine consumption: /llms.txt for the index, /llms-full.txt for the complete site as one document, and /facts.json for the structured facts, pricing and measurements.
