GitButler
AI Development · Developer Tools · Devops
Git, but better — a modern version control client with stacked branches, parallel workflows, unlimited undo, and first-class support for AI-powered development.
marimo
Data Engineering · Developer Tools
A reactive Python notebook that eliminates hidden state, runs reproducibly, and deploys as a web app or script — stored as pure Python, built for the AI era.
codex
AI Code Assistants · Developer Tools
OpenAI's open-source CLI coding agent that reads, edits, and runs code in your terminal using natural language prompts.
agentgateway
AI Development · Developer Tools · Mcp
An open source AI-native proxy that secures, observes, and governs agent-to-LLM, agent-to-tool, and agent-to-agent communication through MCP, A2A, and unified LLM routing.
cocoindex
AI Development · Data Engineering
An incremental data indexing engine that keeps AI agent context perpetually fresh by reprocessing only what changed.
iii
Developer Tools · Devops
Compose, extend, and observe every backend service in real time using three primitives: Workers, Functions, and Triggers.
monty
AI Development · Developer Tools
Run LLM-generated Python code safely inside your agent—no containers, no CPython, no compromise—with sub-microsecond startup.
SlateDB
Databases · Developer Tools
Embedded KV store built on object storage with zero replication cost
XPipe
Developer Tools · Devops · Networking
A local desktop hub that unifies SSH, Docker, Kubernetes, VMs, and remote desktops into one interface — no agents, no remote setup.
Arroyo
Analytics · Data Engineering
A distributed stream processing engine written in Rust that lets you write SQL to run stateful, real-time computations over data streams with subsecond results.
Fresh
Code Editors · Developer Tools
A zero-configuration terminal text editor with familiar keybindings, full mouse support, LSP-powered IDE features, and a built-in orchestrator for running multiple coding agents in parallel worktrees.
Rivet
AI Agents · Developer Tools
Stateful actors as a primitive for AI agents, real-time collaboration, and durable execution — with in-memory state, WebSockets, queues, and scheduling built in.
skrub
Developer Tools
Turn messy real-world dataframes into machine learning features — no manual wrangling required.
headroom
AI Development · Developer Tools
Compress everything your AI agent reads — tool outputs, logs, RAG chunks, and files — before it reaches the LLM, achieving 60–95% fewer tokens with the same answers.
OpenSandbox
Developer Tools · Security
Secure, fast, and extensible sandbox runtime for AI agents with multi-language SDKs and Docker/Kubernetes runtimes.
OpenShell
AI Agents · Developer Tools
The safe, private runtime that lets autonomous AI agents operate in sandboxed environments governed by declarative YAML policies — blocking data exfiltration, credential leaks, and unauthorized network activity before they happen.
Bugsink
Developer Tools · Monitoring
Self-hosted error tracking that accepts Sentry SDKs out of the box, so you keep your instrumentation and drop the monthly bill.
herdr
AI Agents · Developer Tools
A terminal-native agent multiplexer that runs Claude, Codex, Gemini, and other coding agents side by side in real, persistent panes you can detach from and reattach to from anywhere.
magika
Developer Tools · Security
AI-powered file type detection that identifies 200+ content types with ~99% accuracy in milliseconds using a compact deep learning model.
sirchmunk
AI Development · Data Engineering
Drop your files and search them instantly — no vector DB, no indexing pipeline, just raw data queried by a self-evolving intelligence layer.
Flowfile
Data Engineering
Visual ETL that compiles to Polars — build pipelines on a canvas, export as standalone Python, and run anywhere without platform lock-in.
obscura
AI Agents · Developer Tools
A lightweight, stealthy headless browser written in Rust — drop-in compatible with Puppeteer and Playwright, built for AI agents and web scraping at scale.
fabro
Developer Tools · Devops
Define AI agent workflows as code graphs, route tasks across any LLM, and intervene only where it matters.
knowhere
AI Development · AI Memory · Developer Tools
Transform messy, unstructured documents into persistent, navigable memory that AI agents can actually use.
