Breakneck

About Breakneck

Breakneck is a .NET SaaS backend starter kit, sold once for lifetime access, aimed at C# developers who want to ship an MVP without first rebuilding auth, billing and project structure. Its opinion is explicit and contrarian for the ecosystem: no DDD, no clean or onion architecture, no domain events and no layers of abstraction. It uses vertical slice architecture on FastEndpoints so a feature is one slice rather than a change spread across five projects, and the creator's stated goal is to show that .NET does not have to be corporate — or corporate-priced — as a side-project stack. What ships: JWT and API-key authentication with fully customizable entities built on Microsoft Identity and stored in your own database, configurable per endpoint; metered endpoints that track per-user API consumption so usage-based billing is possible statically or dynamically; Stripe integration with webhook handling for checkout sessions and subscribe/unsubscribe events; EF Core configured; Hangfire for background jobs; templated emails from .cshtml files; structured request logging; and unit and integration tests using TestContainers, which spin up a real database and the real API rather than mocks. A project template lets features like auth, billing or the examples be opted out of at generation time. Pricing is a single one-time purchase — no subscription, no per-project fee — covering unlimited projects, lifetime repository access for one user, all current and future features, and lifetime access to a Discord support server. The site's changelog was last dated October 2024, which is worth checking against your own currency requirements before buying.
