Production projects

Developer Tool Classic Supabase Studio Centering the developer experience around PostgreSQL allows Supabase Studio to provide spreadsheet-like table editing and SQL execution directly on production databases.
Scheduling SaaS Classic Cal.com Splitting the tRPC-based web app from an independently versioned NestJS Platform API lets Cal.com serve both its own product and third-party developers from one monorepo, while Turborepo and per-integration app-store packages keep dozens of calendar/payment providers buildable and testable in isolation.
Multi-Agent Interactive AI Classroom Classic OpenMAIC Built as a Next.js app around a set of npm-published packages (slide DSL, generation, renderer, editor, importer, storage). The multi-agent LangGraph pipeline, the slide format and persistence can each be reused or swapped, and heavy video rendering runs in a separate container.
Native macOS Launcher & Clipboard Manager Hybrid Tinycast Staying native with zero third-party dependencies and delegating search to Spotlight and system services keeps memory use low. A small embedded JavaScriptCore runtime adds Raycast extension compatibility without pulling in Electron.
Next.js-Native Headless CMS & App Framework Hybrid Payload CMS A pnpm and Turborepo monorepo lets one core package share a common database-adapter export shape across MongoDB, Postgres, SQLite, and D1, while GraphQL, storage providers, and deployment templates stay in separate packages so a project only pulls in the pieces its target host and database actually need.
End-to-End Typesafe API Framework Hybrid tRPC tRPC connects backend procedure implementations directly to frontend React hooks with zero-boilerplate type inference.
Copy-Paste UI Component Architecture Hybrid shadcn/ui Distributing components as source code gives developers full ownership and customization freedom while pairing Radix accessibility with Tailwind utility styling.
Enterprise Internal Tool & CRUD Framework Hybrid Refine Decoupling CRUD state and data fetching from UI design systems enables developers to build customized enterprise dashboards rapidly without framework lock-in.
Federated GraphQL API Gateway Hybrid Cosmo (WunderGraph) Splitting the Go router (runtime query execution) from the TypeScript Controlplane (schema registry and management) lets Cosmo scale and deploy the performance-critical data path independently, while a dedicated ClickHouse-backed metrics service keeps high-volume usage analytics off the primary Postgres database.
AI Memory & Context Engine AI-agent Mem0 Keeping the core library provider-agnostic through optional dependency groups, while the hosted server bundles a fixed set of vector stores, LLM providers, auth, and rate limiting behind its own FastAPI app, lets self-hosters install a minimal footprint without forking the managed-service code path.
Data Pipeline Engine Hybrid Mage AI A Tornado Python server handles orchestration over a SQLAlchemy and Alembic-modeled Postgres database, while the pipeline editor ships as an independent Next.js frontend, and Spark or dbt support is layered in through opt-in Docker images and bundled adapters.
Open-Source SaaS Template AI-agent Taxonomy Built to demonstrate the App Router, server components, and Next.js 13 data fetching patterns in one realistic, full-featured codebase.
LLM Observability AI-agent Langfuse Storage is split by workload: Postgres via Prisma for relational app state, ClickHouse for high-volume trace analytics, and Redis-backed BullMQ for async jobs, while a separate Rust Axum service handles latency-sensitive LLM proxying outside the Node runtime.
Conversational Form Builder AI-agent Typebot The editor and the chat runtime are separate Next.js apps built from one Dockerfile, so the public chat runtime scales apart from the editor. Bot logic, Forge integration blocks and the Prisma schema live in shared Bun workspace packages that both apps use.
Document Analytics SaaS AI-agent Papermark Splitting enterprise-only code into an ee/ directory keeps the open-source core unambiguous, while pluggable S3-or-Vercel-Blob storage, a separate Tinybird analytics pipeline, and Trigger.dev-managed background jobs let the same Next.js app scale from a Vercel deployment to a self-hosted one.
LLM App Builder AI-agent Dify.ai Agent execution and vector retrieval are split into separate, independently scalable services (a Go sandbox runtime, a FastAPI agent orchestrator, and pluggable vector-store providers) so untrusted tool code and swappable retrieval backends stay out of the core Flask API process.
Survey & Feedback SaaS AI-agent Formbricks A pnpm/Turborepo workspace with a shared dependency catalog lets the web app, background jobs, caching, and AI provider config ship as separate packages while a dedicated Authzed service keeps permission logic out of application code.
Web Analytics Hybrid Umami Umami provides cookie-free, GDPR-compliant website metrics and session replays with simple self-hosting and zero data monetization.
Link & Analytics SaaS Hybrid Dub A Turborepo pnpm monorepo lets the Next.js dashboard, publishable SDKs, and embeddable widgets share code while each ships and versions independently, with click analytics offloaded to Tinybird to keep MySQL fast.
