| API | FOSSBilling provides a REST API with admin, authenticated-client, and public guest endpoints. | Rerun states that it currently has no public API; HTML buttons for hosted checkout are the deeper website integration option. |
| Security | Documented protections include HTTPS enforcement, session fingerprinting, CSRF protection, rate limiting, IP blocking, CAPTCHA, and activity logs. | Rerun says Trustwave certifies its site and that it uses 256-bit SSL, Forte tokenization and Forte's PCI DSS environment without storing payment-method information itself. |
| Self-hosting | FOSSBilling is self-hosted, so the operator keeps the data and controls infrastructure, backups, and security policies. | The license grants use only on a server controlled by Rerun, so customer self-hosting is not provided. |
| Support | The project points users to its documentation, community Discord, and email address for assistance. | The product site advertises free U.S.-based support by email and links to a knowledge base and video tutorials. |
| What it does | FOSSBilling is a billing and client-management system for hosting providers and digital-service businesses. | Rerun is a web application for recurring, subscription and membership billing, payment collection and related customer communications. |

In their own words
FOSSBilling
FOSSBilling is free, open-source billing and client-management software for hosting and other online service businesses. It can issue invoices automatically, send payment reminders, handle recurring or one-time pricing, support multiple currencies and apply promo codes. Hosting products can create and manage accounts through cPanel/WHM, DirectAdmin, HestiaCP, CWP and Plesk. Domain functions cover registration, renewal, transfers and WHOIS checks through registrar integrations, though domain prices are entered manually rather than retrieved live. A REST API provides admin, authenticated-client and public guest endpoints. Documented protections include HTTPS enforcement, session fingerprinting, CSRF protection, rate limiting, IP blocking, CAPTCHA and activity logs. It is self-hosted, requiring PHP 8.3, 8.4 or 8.5 and a MySQL-compatible database, with Apache, LiteSpeed/OpenLiteSpeed or NGINX. The project is beta, under active development, and notes rough edges and limited support.
Rerun
Rerun is a web app for recurring, subscription, and membership invoices and payments. It handles recurring credit card and ACH payments as well as recurring invoice billing. Payment streams can specify dates, frequency, amounts, discounts, surcharges, and up to two tax codes per customer. A secure My Account page lets customers update payment or contact details, view payment history, and pay open invoices. Businesses can customize emails for upcoming, successful, or unsuccessful payment events. Reports support filters, date ranges, configurable columns, and Excel export. Hosted checkout can be customized for recurring or one-time payments and donations. Rerun syncs customer and accounting data with QuickBooks Online and Xero, and can send key notifications to Slack. The Pay as you go plan has no monthly fee, but transaction fees apply: 2.95% + 30¢ for Visa, Mastercard, and Discover; 2.99% + 30¢ for Amex; and $1.49 per ACH transaction. The 30-day trial uses sample data, requires no credit card, and does not permit real transactions. Rerun is for US use and processes transactions in USD.
