Looking for a free or open-source alternative to Chargebee? Billoop is the closest direct swap — MIT-licensed source on GitHub, or a $49 one-time packaged install. Since you're already auditing what you pay Chargebee 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. Billoop — replaces Chargebee
Plans, coupons, real proration, dunning and an MRR dashboard on your own Stripe account. $49 once vs Chargebee's $599+/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 Chargebee — they're trying to be the last subscription you pay for that specific job.
