BitCart 🧰 Platform Open source

BitCart is a free, open-source (MIT-licensed) payment processor you self-host via Docker to accept cryptocurrency directly into your own wallets. It's non-custodial: funds go straight to addresses you control rather than sitting with a third-party processor, and it supports a wide range of coins including Bitcoin, Litecoin, Bitcoin Cash, Monero, Ethereum, Tron, and stablecoins like USDT, with an ETH-plugin architecture that has expanded chain support over time.

The project publishes a clear headline pricing claim on its site: 0% platform fees, with no third party taking a cut — you only ever pay the underlying blockchain's network fees. It ships a store front-end, a merchant API, plugins/extensions, a setup configurator, and maintains public documentation plus Telegram/Discord/Matrix community channels, all signs of a genuinely maintained project rather than an abandoned repo.

Who it's for: merchants, developers and self-hosters who specifically want to accept crypto payments without paying a payment processor's percentage fee and without giving up custody of funds — a natural fit for stores, digital-goods sellers or donation pages targeting a crypto-native audience. It is not a fit for anyone who wants a hosted, zero-maintenance checkout, or who needs to accept card/fiat payments — BitCart is crypto-only and requires you to run and secure your own server and wallets.

Requirements: Docker-based self-hosting, comfort managing node/wallet infrastructure (or using their hosted daemons), and your own handling of tax/compliance reporting since there's no merchant-of-record layer.

Strengths: real 0% platform fee, non-custodial security model, broad coin support, active MIT-licensed development. Weaknesses: self-hosting adds real operational overhead, the project doesn't publish a formal payout-timing SLA or payout minimum since funds go straight to your wallet rather than being batched and remitted, and community/support scale is smaller than centralized crypto processors. Good fit for technically capable merchants wanting a crypto-only, fee-free processor; not for non-technical publishers or anyone needing fiat rails.
