All Open Source Apps

Privacy-first metasearch engine that aggregates results from 250+ search services — no tracking, no profiling, full control when self-hosted.

Open-source flat-file CMS for publishing Markdown-based documentation, manuals, and eBooks without a database.

Self-hostable open source email platform built on Amazon SES with a full dashboard, SMTP relay, REST API, and multi-language SDKs.

A self-hosted, AI-powered card note-taking tool that lets you capture fleeting thoughts instantly and retrieve them with natural language search.

A desktop IDE built on an infinite canvas — spread code editors, terminals, browsers, docs, and AI agents across freeform space instead of stacking windows and tabs, with layouts restored automatically.

A keyboard-driven terminal dashboard for managing cron jobs on local machines and remote servers via SSH.

A universal swarm intelligence engine that spawns thousands of autonomous AI agents to simulate and predict how real-world events unfold across social, financial, and political domains.

A no-code PostgreSQL database with spreadsheet UX, real-time collaboration, and native AI agents — built for teams that outgrow Airtable.

A pretrained decoder-only foundation model by Google Research that delivers zero-shot time series forecasting with calibrated quantile prediction intervals — no training required.

An all-in-one open-source training suite for finetuning diffusion models—FLUX, SDXL, Wan video, and audio—on consumer GPU hardware via CLI or web UI.

A complete, embeddable search engine and RAG pipeline running in browsers, servers, and edge networks with full-text, vector, and hybrid search in under 2KB.

A unified, self-hosted platform for job scheduling, visual workflow automation, server monitoring, alerting, and incident response — built for teams who demand full ownership of their operations stack.

Design database schemas visually in your browser and export executable SQL for any major database — no account required.

Self-hosted RSS reader and personal knowledge management tool with MCP server integration for AI assistant connectivity.

Self-hosted invoicing without the bloat

Self-hosted URL shortener with custom domains, per-link analytics, and zero build step required.

Open-source status pages and uptime monitoring with global synthetic checks, monitoring-as-code, and AI agent integration via MCP.

A decentralized, open-source writing platform that permanently stores your stories on the Stacks blockchain and Arweave — where Web3 content creators own their words forever.

An open-source runtime control plane for AI agents — define safety guardrails once, apply them across agents built on LangChain, CrewAI, Google ADK, or AWS Strands, and update controls without redeploying code.

Persistent memory for AI coding agents — built on the iii engine, it works across Claude Code, GitHub Copilot CLI, Cursor, Gemini CLI, Codex CLI, and any MCP client, so agents stop needing everything re-explained every session.

Open-source coding agent for VS Code, JetBrains, and CLI with support for 30+ LLM providers.

Open-source, self-hosted LMS for selling online courses, digital downloads, and building communities on your own branded website.

Build and run agentic workflows across channels with YAML, tools, and RAG

A biologically-inspired memory layer for AI coding agents — memories decay by default and strengthen through use, modeled on the hippocampus, with zero runtime dependencies and a SQLite backbone.
