Explore Verified Production Tech Stacks
28+ battle-tested open-source software architectures with architectural rationale, reliability metrics, and instant AI scaffolding prompts.
The world's most deployed self-hosted cloud office suite; gives complete data sovereignty over files, calendars, office collaboration, and communications without third-party surveillance.
Leading self-hosted Zapier alternative; combines an intuitive Vue visual canvas with a high-throughput Node.js execution engine and built-in AI agent reasoning nodes.
Next-generation drop-in replacement for Redis and Memcached. Delivers 25x higher throughput and sub-millisecond tail latency by utilizing a modern shared-nothing multi-threaded architecture with Linux io_uring asynchronous I/O and custom memory serialization.
Self-hosted AI conversation and autonomous agent workspace supporting all major LLMs (OpenAI, Anthropic, Ollama, HuggingFace). Built with Node.js Express, MongoDB for flexible conversation trees, Redis for rate limiting and streaming buffers, and a responsive React UI.
Lightweight Sentry-compatible application performance monitoring and error tracking platform. Built on Python Django and PostgreSQL with async Celery task queues for high-volume exception ingestion and Redis message buffering.
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.
Choose your stack based on real projects, not guesswork. Context: Launch this week as fast as possible driver. Survey verified stack.
High-performance Google Photos alternative; utilizes SvelteKit and NestJS with background Python workers for hardware-accelerated transcoding and facial recognition.
Universal memory layer for AI agents; extracts and persists structured personal facts and episodic memories across user chat sessions with low latency.
Open-source Zapier alternative; combines an Angular graph UI with Fastify and sandboxed V8 execution workers for high-volume webhook triggers.
Frequently Asked Questions
Everything you need to know about how this directory works.
What counts as a "verified" production stack?
A verified badge means the architecture is either a well-known curated open-source project we benchmarked directly from its public repository, or a community submission whose maintainer claimed the listing and confirmed the stack, scale, and reliability details are accurate.
Can I submit my own project to this directory?
Yes. Click "Share Your Stack" to submit your production architecture — name, tech stack, team scale, and why you chose it. Submissions are reviewed and go live as community listings; you can claim and verify them later from the project page.
What is the difference between AI-Agent, Hybrid, and Classic modes?
AI-Agent means the majority of the codebase was generated by an AI coding agent with light human review. Hybrid means agent-generated code paired with active human pair programming. Classic means the codebase was hand-written with AI used only for assistance, not generation.
How is the "Most Upvoted" sort order calculated?
Upvotes are community signals from engineers confirming a stack worked well for a production use case similar to theirs. The default sort ranks by net upvotes, then by most recently verified, so newer confirmations surface architectures that are still actively maintained.
Stack information is sourced from each project's public repository (package.json, go.mod, requirements.txt, or equivalent) and is not affiliated with or endorsed by the listed projects.
