Banned by Stripe
Your account got reviewed. Funds held for 90 days. No explanation. Three months building, gone in one email.
Locked into platforms
Polar takes 4%. Lemon Squeezy 5%. Gumroad 10%. Plus chargebacks. Plus their banned-categories list. Plus their data ownership.
Crypto tools suck
BTCPay is Bitcoin-only. Bitcart has no auth. Helio is Solana-only closed source. Nobody connects payments + users in one stack.

(Community)All payments are non-custodial. Funds go directly from customer's wallet to yours. OpenBitum never has access to funds.

How OpenBitum compares
| Feature | OpenBitum | Polar.sh | Clerk | BTCPay |
|---|---|---|---|---|
| Open-source | AGPL | Source-available | No | MIT |
| Self-hosted | Docker | Cloud-only | No | Yes |
| Crypto payments | EVM+Solana+BTC | via Stripe | No | BTC only |
| User management | Logto-powered | Basic | Best-in-class | No |
| Take rate | 0% | 4% + $0.40 | -n/a | 0% |
| KYC required | No | via Stripe | -n/a | No |
| Solana support | Native | No | No | No |
Honest comparison. Polar.sh is great if you want cloud + fiat. Clerk is best-in-class for pure auth. BTCPay if you're Bitcoin-only. OpenBitum is the right choice if you want OSS + self-host + multi-chain crypto + auth in one.

FAQ
MVP is production-ready for most use cases. We're using it ourselves for OpenBitum's own billing (Cloud tier when it launches). Bugs exist — we ship fixes weekly. See changelog.
For the merchant side, mostly no — you create a wallet (we recommend Ledger hardware) and OpenBitum handles the rest. For customers, they need a crypto wallet to pay. Crypto-naive customers are not your target if you choose OpenBitum.
AGPL ensures the code stays open. Same license used by Cal.com, Lago, PostHog. Enterprise customers concerned about AGPL can buy commercial license (contact us).
Code is AGPL — your install keeps running forever. Postgres dump = full export of your data. No vendor lock-in. We use Logto + Bitcart, both established OSS projects — if we disappear, the underlying parts remain.
Cloud-managed subscriptions (when it launches). Enterprise support contracts. Commercial licensing for proprietary integrations. We will never put core features behind paywall — that's not what AGPL allows anyway.
Yes. Many merchants use only stablecoins (USDC, USDT) — these are pegged 1:1 to USD, so feels like dollar-denominated. Customers can pay with their crypto wallet, you get USDC, convert to USD whenever you want.
OpenBitum is software, not a financial service. Tax compliance is the merchant's responsibility. We don't collect VAT, don't track sales tax, don't generate tax forms. Consider this when planning. Stripe Atlas + Quaderno is what you'd add for compliance automation if needed.
BTC + Lightning, Ethereum, Base, Polygon, Arbitrum, Tron (USDT), Solana (USDC/USDT/SOL). More chains added based on community demand. See docs/chains.
Technically yes — but OpenBitum is optimized for digital products / access / SaaS / memberships. For physical goods, you'd need to handle shipping integration yourself.
Don't trust — verify. Audit the AGPL code yourself. Self-host so we never touch your data. We're built on Logto + Bitcart, both established OSS projects. Funds are non-custodial — we technically cannot steal them.
