Wasmer
Developer Tools · Devops
A fast, secure WebAssembly runtime that runs lightweight containers anywhere — from desktop and cloud to the edge and the browser.
Baserow
Databases · No Code Platforms
Open-source no-code platform to build databases, apps, automations, and AI agents — self-hosted or cloud, with full data ownership.
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.
ParadeDB
Analytics · Databases · Search
Born out of Y Combinator's S2023 batch, ParadeDB is a Postgres extension that delivers Elasticsearch-quality BM25 search and real-time analytics without a separate search cluster to manage.
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.
Sonic
Databases · Search
Fast, lightweight, schema-less search backend in Rust — microsecond queries, 30MB RAM, no document storage required.
Fluree DB
Databases
A temporal, verifiable graph database with git-like branching, integrated vector/text/geo search, and RDF/SPARQL/JSON-LD/openCypher support — benchmarked at 10.4x faster than the next database on the full Wikidata dump.
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.
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.
helix-db
Databases
A graph-vector database built from scratch in Rust that unifies graph traversal, vector search, key-value, and relational storage into a single platform for AI applications.
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.
OpenViking
AI Development · AI Memory · Databases
An open-source context database that gives AI agents a unified filesystem for memory, resources, and skills with hierarchical tiered retrieval.
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.
