Payment-processing tools differ sharply in what they handle: some coordinate existing providers, some focus on regional payment rails, and others process cryptocurrency payments. ToolVitals compared seven open/source-visible projects using its July 2026 dataset, including overall, health, shipping, and GitHub popularity signals.
The ranking is ordered by ToolVitals score first, with GitHub stars used only as a secondary popularity signal for ties. The supplied scores and ordering are preserved, and openness and license classifications are reported without treating source-available or open-core software as OSI open source.

Top 3 Highlights
OwnPay ranks first with a ToolVitals score of 85, a shipping score of 84, and a health score of 76. Its current site positions it as self-hosted payment infrastructure rather than a payment processor: operators connect external gateways while retaining their own checkout domain and data. It also documents a plugin-based gateway catalog, double-entry bookkeeping, multi-brand operation, a REST API, and signed webhooks. OwnPay is classified as OSI-approved OSS under AGPL-3.0.
lomi. ranks second with a ToolVitals score of 82, a shipping score of 81, and a health score of 71. Its current positioning is unusually specific: payment infrastructure for francophone West Africa, combining hosted checkout and direct charges with cards, Mobile Money, direct bank debits, and SPI payments across UEMOA. The platform also supports recurring revenue, merchant payouts, and transaction analytics. lomi. is classified as OSI-approved OSS under AGPL-3.0.
XCash ranks third with a ToolVitals score of 79, a health score of 74, and a shipping score of 70. Its first-party site describes a self-hosted, non-custodial cryptocurrency gateway for invoice payments and account-style deposits, with funds routed directly to merchant wallets. It supports EVM-compatible chains and Tron, exposes a REST API and webhooks, and provides a Docker Compose deployment path. XCash is classified as OSI-approved OSS under MIT.
