§01
Overview
- What it is: A production SaaS starter kit — a polished, "productized" version of the user's personal fullstack scaffold. The README positions it as an indie-hacker boilerplate: "Built by indie hackers who've shipped 4+ production SaaS apps with this exact stack". Includes payments (Polar.sh: checkout + webhooks + subscriptions), auth/RBAC, dark mode, i18n, SEO (sitemap/robots/JSON-LD), AI-native config.
- Type / status / role: library/boilerplate · active · solo — the user is the author (18 commits), +2 commits by Claude (AI co-author — literal co-development with AI).
- Active period: 2025-11-10 → 2026-05-01 (~6 months of iterative polishing).
§02
Stack
- Monorepo: Turborepo + Bun workspaces. Apps:
web(Next.js 16.1 + React 19.2),api(Elysia + Swagger + cookie/cors + Resend),admin(Next.js). Packages: auth/cache/cli/db/email/entities/eslint-config/typescript-config/ui (identical to fin_fullstack — shared foundation). - Key pieces: Better Auth (login/signup/sessions/RBAC/admin), Drizzle ORM, Eden Treaty (end-to-end types), shadcn/ui + Tailwind, next-intl (i18n), next-themes (dark mode), Polar.sh (payments/subscriptions), Resend (email), SEO (sitemap/robots/JSON-LD/metadata).
- AI-native:
CLAUDE.md(guide for Claude Code/Cursor/Copilot/Windsurf) +.claude/skills/(deploy-workflow, dev-workflow, ui-ux-design, polar — based on context from hermes-shipkit). - Infra: Bun, Turbo pipeline, Docker-ready.
§03
What was shipped
20 commits in 6 months (solo + AI):
- Full SaaS scaffold: auth+RBAC+admin, payments (Polar.sh checkout/webhook/subscription), email (Resend), i18n, dark mode, SEO.
- Monorepo of 3 apps + 9 packages with Eden type-safety.
- AI-native wiring (CLAUDE.md + skills) — optimized for agentic development.
- 2 commits authored by Claude — literal AI co-development.
- Volume: compact, but production-complete and "sellable" boilerplate.
§04
Technical challenges
Confirmed by README/CLAUDE/manifests:
- Productized fullstack foundation (apps + 9 packages, Eden type-safety): one scaffold, forkable into products — proven (4+ live SaaS on it). → systematic reuse, platform thinking.
- Payments out of the box (Polar.sh: checkout + webhook + subscription): full billing cycle as part of the boilerplate, with accumulated rules ("payment = 3 parts, never deploy without one"). → knowledge of real billing pitfalls.
- AI-native by design (CLAUDE.md +
.claude/skills/): boilerplate designed for agentic development (skills for deploy/dev/ui/polar), supporting Claude Code/Cursor/Copilot/Windsurf. → advanced AI workflow as a product feature. - Production lessons captured (BetterAuth baseURL gotcha, semantic tokens for dark mode, Turbo build race, SEO indexing) — institutional knowledge from real deployments.
- End-to-end type safety (Elysia → Eden Treaty → frontends).
§05
AI-assisted development
- Sessions found: 4 (in the local Claude Code sessions directory, 4
.jsonl+ subdir). Plus 2 git commits authored byClaude <noreply@anthropic.com>. - What was done with AI: development/polishing of the boilerplate with Claude Code; the boilerplate itself is AI-native (skills/CLAUDE.md for future projects).
- AI-workflow patterns: AI as co-developer (commits from Claude), AI-native product (skills as reusable workflows), multi-tool (Claude Code + Cursor + Copilot + Windsurf).
§06
Achievements & metrics
- Foundation of 4+ production SaaS apps (per README claim — backed by the ecommerce_sass/fin_fullstack/pos_fullstack/hermes cluster).
- 3 apps + 9 packages, Polar.sh payments, Better Auth/RBAC, i18n, SEO, dark mode out of the box.
- AI-native: CLAUDE.md + 4 skills, support for 4 AI assistants.
- 2026 stack: Next 16 + React 19 + Elysia/Bun + Drizzle.
