All Open Source Apps

Turn bare metal servers into a fully managed cloud platform with a single Kubernetes-native REST API.

The batteries-included Python agent harness — planning, sub-agents, filesystem, shell, memory, and skills bundled in, built on LangGraph.

Open-source collaborative knowledge platform with real-time editing, AI writing tools, and full self-hosting control — built by the French and German governments.

Open source document signing platform with WYSIWYG PDF builder, multi-party workflows, REST API, and full self-hosting via Docker.

Lightweight self-hosted personal finance manager with AI receipt scanning, multi-currency support, and MCP integration for complete data privacy.

Open-source feedback portal where customers submit, vote on, and track feature requests so product teams build what actually matters.

The painless self-hosted Git service that runs on anything from a Raspberry Pi to a $5 cloud droplet, delivering GitHub-like workflows as a single Go binary.

A Postgres-backed orchestration engine for background tasks, AI agents, and durable workflows that replaces Redis queues and multi-datastore durable execution platforms with a single self-hostable service.

Self-hosted read-it-later platform with highlights, newsletters, PDFs, and seamless Obsidian and Logseq integration.

Self-host your own Google Analytics alternative with heatmaps, session recordings, and full data ownership — no cloud required.

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.

Postgres-native ETL that streams change data capture in real time to Snowflake, BigQuery, ClickHouse, S3, and Kafka — up to 10x faster than general-purpose pipelines, managed through a familiar Postgres SQL interface.

The open-source API layer that turns local LLMs into production private AI applications with full Claude API compatibility

Cloud-native search engine for logs and traces, delivering sub-second search directly on S3, GCS, or Azure Blob storage at a fraction of Elasticsearch's cost.

The fastest BI tool for humans and agents — define metrics, models, and dashboards as code and query them instantly on ClickHouse or DuckDB.

Embedded KV store built on object storage with zero replication cost

Fast, lightweight, schema-less search backend in Rust — microsecond queries, 30MB RAM, no document storage required.

The open-source, unlimited NotebookLM alternative with real-time collaboration, a desktop app, and no vendor lock-in.

Unofficial Bitwarden-compatible server in Rust — run the full Bitwarden ecosystem on a Raspberry Pi using every official client you already have, without the multi-container overhead.

The world's most popular open-source CMS — now with a built-in AI client SDK, 196 native blocks, and full-site editing for PHP-powered publishing at any scale.

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.

An incremental data indexing engine that keeps AI agent context perpetually fresh by reprocessing only what changed.

An open-source CLI that packages machine learning models into standard, production-ready Docker containers — no Dockerfile wrangling, no CUDA version hell.
