What it runs on, and what runs on it
0 cited edgesComputed from the stack graph, both directions. Every cited edge links the page it was read from; a vendor-added one links the vendor’s own source — this is the reason to be here rather than on the vendor’s own site.
No edges on record for kern.
Nothing in the directory documents depending on it, and its own docs do not name what it runs on. An edge is only stored when a source states it.

Price
We hold no price for this product.
This is open-source software: you can run it yourself and the licence costs nothing. If the project also sells a hosted service, we do not yet hold the page it prices it on. If that changes — or if you publish /.well-known/pricing.json — it appears here with a capture date.

“A fresh container for every call your model makes One container per call, destroyed when the call returns: a hundred calls cost 1.4 s in total and leave nothing behind.”2026-10-06
“A tool-call costs a twentieth of docker run . Most of what is left is CPython starting inside the box, not the box, so a heavier call narrows it: import json,re is 7x rather than 20x. The prewarm bar is what a call gets while the pool keeps up. BENCHMARKS.md has the method. Memory and process limits”2026-10-06
“No daemon. It runs workloads, including agent tool calls and code generated by an LLM, in real containers enforced by the kernel.”2026-09-29

A model that quotes us should quote us correctly. The reading and its date sit inside the citation rather than beside it, because a quotation carrying only a URL goes wrong the week the URL changes.

What kern can and cannot change here
Claiming the organisation lets its admins and editors change the tagline, description, logo, docs link and deployment model of every product that org owns — live, labelled as theirs, and logged. Answers to blank questions and dependencies go live too, marked as the owner’s and sourced; a documented answer cannot be overwritten. Everything else on this page is a stated fact with a dispute route: price, licence and OSS figures. Those columns are ungranted at the database level, so they are not a feature we withheld — they are a write that cannot happen. Name, category, website, pricing page and package names can be changed by the owner only through our review. A dispute never deletes a value; it marks it and publishes the correction.
