Production projects

Agentic Development Environment for Parallel Coding Agents Hybrid Orca Agent CLIs stay the user's own. Orca adds the orchestration layer around them: isolated git worktrees, a PTY daemon that outlives the UI, and a relay for mobile steering. It can support new agents without bundling them.
Claude Code Plugin Classic Fast Jev Compaction Two Jev Noul questions per tool call, gated by a threshold in code, prune a transcript without rewriting it, and a thin hook adapter falls back to Claude Code's built-in summary whenever Jev fails or saves too little.
Browser-Based 3D Geospatial Intelligence Simulator Hybrid God's Eye View All rendering runs client-side on Cesium with plain JavaScript modules, while a thin localhost Node proxy per data provider keeps keys out of the browser, so the whole product installs and runs locally with no hosted backend or database.
Hybrid Deterministic + LLM Agent Code Review Tool Hybrid Open Code Review A single static Go binary keeps the review engine fast and easy to distribute through npm, CI and IDE plugins. Putting deterministic diff/context analysis before a narrow LLM loop keeps reviews precise and cheap in tokens compared with general-purpose agents.
Open-Source Team Communications & WebRTC Classic Rocket.Chat Combining full on-premises MongoDB ownership with real-time WebSockets gives enterprise organizations secure, private communication without third-party surveillance.
End-to-End Typesafe API Framework Hybrid tRPC tRPC connects backend procedure implementations directly to frontend React hooks with zero-boilerplate type inference.
Island Architecture Web Framework Hybrid Astro Vite as a first-class dependency and per-framework, per-host integration packages let Astro ship a fast static-first build while opting into server rendering or client hydration only where a project actually needs it.
Fair-Code Workflow Automation & AI Integrator Hybrid n8n n8n splits its execution engine, workflow schema, and integration nodes into separate TypeORM- and Express-backed packages so the automation runtime, node library, and Vue editor can be built, tested, and versioned independently inside one Turborepo-orchestrated pnpm workspace.
Utility-First CSS Engine & Framework Classic Tailwind CSS Tailwind CSS re-architected its compilation engine with Rust Oxide and Lightning CSS for near-instant builds and zero-config CSS integration.
Fullstack React Framework Hybrid Next.js Performance-critical compilation and bundling are implemented as Rust crates (Turbopack, SWC transforms) compiled to native addons, while the framework surface stays in TypeScript, letting Next.js run its full test matrix across three interchangeable bundlers without forking the codebase.
Automated GraphQL API Engine Classic PostGraphile Synthesizing GraphQL APIs directly from PostgreSQL catalogs eliminates manual resolver boilerplate while Grafast planning solves N+1 query overhead at the database layer.
Headless Browser Automation Infrastructure Classic Browserless A base Node.js/TypeScript image is specialized into per-browser Docker builds (and one combined multi-browser build) so deployments only ship the browser binaries and system libraries they actually need, while a single TypeScript server handles session pooling, queueing and protocol translation for all of them.
Workflow Automation & AI Orchestration Hybrid Activepieces A queue-backed API/worker split on Fastify, PostgreSQL and Redis lets executions scale horizontally, while a typed pieces framework and isolated execution keep community integrations safe to load at runtime.
Low-Code Internal Tool Platform Classic Appsmith A reactive Spring Boot server with PF4J plugins isolates dozens of datasource integrations, MongoDB stores app definitions as documents, and a single supervisord-managed image keeps self-hosting to one container.
Developer Data Platform Classic Crowd.dev Decomposing ingestion, enrichment, and merging into many independent Temporal-orchestrated worker services under services/apps lets crowd.dev scale each pipeline stage separately, while shared @crowd/* libraries keep database, queue, search, and cache access consistent across all of them.
Headless CMS Classic Strapi Declarative content modeling paired with a customizable React admin dashboard gives engineering teams full control over content structures and delivery APIs.
Headless CMS Classic Directus A Knex-based query layer and adapter packages for storage keep the same API and Studio working across many SQL vendors and object stores, while extension code runs inside an isolated-vm sandbox so third-party hooks cannot destabilize the main API process.
Content Platform Classic Ghost Ghost runs its core server, a React admin app that is replacing a legacy Ember admin in place, and every public-facing widget as separately Vite-built packages inside one pnpm/Nx monorepo, so the publishing surface, the editor and each embeddable script can evolve and ship on their own schedule.
E-commerce API Classic Medusa Splitting commerce logic into independently versioned @medusajs packages, backed by a pluggable workflow engine (in-memory for development, Redis and BullMQ for production), lets teams customize or replace individual modules without forking the whole platform.
