Keymaster on Web Browser
Runs in any modern browser — nothing to install, works the same on any machine you log in from.
Setup on Web Browser
Download the installer
Download the latest Keymaster installer from the GitHub Releases page (https://github.com/bensblueprints/keymaster-mvp/releases) — or build it yourself from the MIT source.
Install
Run the installer — one click, no terminal, no account to create.
Run it locally
Keymaster runs 100% on your machine — no account, no telemetry, and it keeps working with the Wi-Fi off.
What works offline: everything. Keymaster is a desktop app — once it's installed, no feature needs a connection to us.
Keymaster on Web Browser — honest answers
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/keymaster-mvp, always. $129 buys the packaged installer, updates and priority support. We dogfood it: the onetime-suite's own premium tiers run on Keymaster.
Can offline validation catch revoked keys?
No — and the docs say so upfront. An offline check proves a key is authentic and unexpired; it can't see revocations or seat counts. The shipped snippets show the recommended hybrid: verify offline instantly, check in online periodically, apply a grace period.
