Looking for a free or open-source alternative to Doppler Team? Secretbox is the closest direct swap — MIT-licensed source on GitHub, or a $39 one-time packaged install. Since you're already auditing what you pay Doppler Team every month, here are four more pay-once tools from the same catalog worth a look while you're at it — different jobs, same idea: buy the software once instead of renting it forever.
1. Secretbox — replaces Doppler Team
Projects, environments and versioned secrets with a CLI that pipes straight into your .env. $39 once vs Doppler Team's $12/user/mo. Free on GitHub, or the packaged installer on Whop.

Why this list is worth bookmarking
Every app above is a one-time purchase with MIT-licensed source, no accounts with us and no telemetry. None of them are trying to be the next Doppler Team — they're trying to be the last subscription you pay for that specific job.
