open-source
the open standard for sealing anything.
The open standard for proving any file is real, unaltered, sealed by a known certificate, and in existence by a certain date. One standard for every kind of file: documents, images, email, code, containers. Verifiable by anyone, forever. The proof travels with the file and stands on its own.

Keeps your Claude session warm for you.
Stop paying to rebuild your Claude Code cache. When your main agent waits on a subagent for more than 5 minutes, its prompt cache silently expires, and the next turn re-encodes your entire conversation at the write rate instead of reading it back cheap. On long sessions with many subagents that's roughly 20% of your bill. claude-thermos keeps the cache warm so you never pay that tax.
