I built Kairex because an expired API token broke prod and nobody noticed for a day

I'm a solo developer and I kept getting burned by credentials expiring with no warning — an expired TLS cert taking down a service on a weekend, a third-party API token quietly dying and breaking a background job nobody noticed for a day.

SSL monitors only watch certs. Secrets managers like Vault solve a different problem and assume you've migrated everything into them. I wanted the boring middle: track when credentials expire, warn you before they do.

Kairex stores metadata only — name, service, expiry date, owner. Never the secret value itself. It is not a secrets manager and I don't want it to be.

Free tier is 10 credentials. Paid is $9.99/mo and $49.99/mo for teams. 30-day trial.

It's brand new. I'd genuinely love harsh feedback — especially on whether this maps to how your team actually handles credential sprawl today.
