New AI agents now ask first

Your app's keys.
Safe in one place.

Drop in a certificate, keystore or API key. DevVault reads it and locks it away.

Free and open source

Reads the files you already have

Never miss
an expiry.

Dates come straight from the file. DevVault reminds you before a certificate or profile runs out.

AI agents
ask first.

Claude Code, Cursor and others can use a secret only after you click Allow. The value never reaches the model.

Sync through
your own bucket.

Use Cloudflare R2, S3, Backblaze B2 or MinIO. There is no DevVault server.

The little things, done right.
