Production Developer Tool & API Projects
Gotify
Self-hosted real-time push notification service (Pushover / Pusher alternative). Built in Go with Gin and WebSockets for low-latency message streaming from CI/CD webhooks, server scripts, and IoT alerts directly to desktop/mobile devices.
Supabase Studio
Database-centric product; most business logic lives in Postgres policies and edge functions.
tRPC
Eliminates API schema drift without code generation; TypeScript compiles client and server code together to infer procedure input, output, and error types automatically.
Prisma
Benchmark developer experience for relational databases; leverages declarative schema modeling to auto-generate fully type-safe TypeScript clients backed by an optimized query engine.
Deno
Modern secure runtime by Ryan Dahl; eliminates node_modules and build pipelines with first-class TypeScript, web standard APIs, and an explicit capability-based security sandbox.
Gitea
Frictionless GitHub alternative; written in Go to run on minimal hardware (even a Raspberry Pi) while providing Git repository management, issue tracking, and Docker-based CI/CD pipelines.
Astro
Content-driven web framework pioneering the Islands Architecture; ships pure semantic HTML by default, selectively hydrating interactive UI components only when visible in viewport.
shadcn/ui
Paradigm shift in design systems; developers own component code directly in their repository without node_modules abstraction lock-in, pairing Radix accessibility with Tailwind.
Bun
Radical reimagining of JS tooling; written from scratch in Zig on WebKit JavaScriptCore for 4x faster module resolution, zero-transpilation TypeScript, and native SQLite speed.
FastAPI
Benchmark for modern Python APIs and AI services; pairs Starlette with Pydantic v2 Rust core for ultra-high throughput and automatic interactive documentation.
Tailwind CSS
Industry-standard utility styling; modern v4 rewrites the core engine in Rust (Oxide) to scan gigabytes of project files and compile CSS in microsecond render cycles.
Next.js
The enterprise React benchmark; leverages React Server Components, server actions, and a high-performance Rust compiler (Turbopack) for maximum SEO and sub-second page loads.
Browserless
Production-grade headless browser grid for automated web scraping, PDF generation, and synthetic testing. Wraps Chromium instances in isolated Docker sandboxes with WebSocket multiplexing, connection pooling, and memory-leak auto-restarts.
Cosmo (WunderGraph)
Open-source GraphQL federation gateway and router written in Go. Compiles subgraphs into unified declarative execution plans with sub-millisecond routing overhead, zero-allocation request pipelines, OTEL distributed tracing, and ClickHouse-backed analytics.
Penpot
Open-source web-based Figma alternative; Clojure backend utilizes open SVG standards directly for pixel-perfect design rendering.
Hoppscotch
Lightweight open-source Postman alternative: runs directly in browser with offline PWA capabilities.
PocketBase
Ultra-compact single binary: zero microservice maintenance overhead, handles 10,000+ RPS on a $5/mo VPS.
Appwrite
Self-contained asynchronous BaaS: async Swoole server delivers ultra-low memory footprint and massive concurrency.
Trigger.dev
Long-running jobs: durable execution layer completely decoupled from web servers.
Novu
Queue-centric architecture: workers scale independently from API, delivery guarantees in queue.
Excalidraw
Client-heavy drawing engine; server is only a lightweight layer for sharing and persistence.
