saaskipShip SaaS. Skip the setup.

The opinionated Next.js SaaS starter for senior devs. Strict tooling, mutation testing, and conventions that scale.

Strict Tooling

ESLint 10 with full plugin suite, Prettier 3, Knip, Gitleaks, axe-core, markdownlint, cspell. Non-negotiable quality contract.

Stryker 10 out of the box. No surviving mutants. Every branch must correspond to a real business rule or testable error case.

Vitest 4 with v8 coverage. Every line of source code is tested. SonarQube integration for continuous quality monitoring.

Playwright 1.55 with chromium. Example e2e test included. CI pipeline installs browsers and uploads reports automatically.

Commitizen, commitlint, and Changesets wired together. Automated version PRs and changelog generation on every merge to main.

GitHub Actions workflows for check, build, e2e, SonarQube, CodeQL, and release. Dependabot with grouped dependency updates.

@t3-oss/env-nextjs with zod schemas. Server and client variables validated at startup. No more undefined at runtime.

src/config.ts surfaces app metadata at the root — title, description, URL, author, logos. The first file to edit when forking.

Built on the latest Next.js with Turbopack. App Router, Server Components, and modern conventions from day one.
