All Open Source Apps

Distributed SQL database for real-time analytics at scale

Developer-first error tracking and performance monitoring platform with AI-powered root-cause analysis across 20+ languages and frameworks.

Open-source backend platform with Auth, Databases, Storage, Functions, Messaging, Realtime, and Sites — deploy via Docker or use Appwrite Cloud.

Open-source enterprise data warehouse unifying analytics, vector search, full-text search, and AI agent orchestration in a single Rust-built engine on S3.

The self-hosted Identity Provider that replaces Okta, Auth0, and Entra ID with a unified SSO platform supporting SAML, OAuth2/OIDC, LDAP, RADIUS, and WebAuthn.

Open-source vector database and search engine built in Rust for production-grade AI applications — from semantic search to RAG pipelines and recommendation systems.

A high-performance, open-source time-series database built for financial market data, IoT telemetry, and real-time analytics, combining a zero-GC Java/C++ core with SIMD-accelerated SQL and a WAL-to-Parquet storage engine.

Open-source, embedded vector database built on the Lance columnar format for fast multimodal search across billions of vectors, backed by Y Combinator (W23).

Self-hosted, end-to-end encrypted password manager API built for teams who demand full ownership of their credentials.

Open-source authentication platform you self-host, giving you complete control over user data with zero vendor lock-in.

Open-source no-code platform to build databases, apps, automations, and AI agents — self-hosted or cloud, with full data ownership.

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.

Open-source agentic security automation platform that runs AI agents and durable workflows at scale with sandboxed execution.

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.

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

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.

Detect malicious network traffic using 47+ live threat feeds, heuristics, and a fat-client reporting dashboard — no commercial stack required.

Embedded KV store built on object storage with zero replication cost

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.

Secure, fast, and extensible sandbox runtime for AI agents with multi-language SDKs and Docker/Kubernetes runtimes.

An open-source context database that gives AI agents a unified filesystem for memory, resources, and skills with hierarchical tiered retrieval.

Self-hosted secure remote access that unifies WireGuard VPN, identity management, and connection-level MFA in one open-source platform.

AI-powered file type detection that identifies 200+ content types with ~99% accuracy in milliseconds using a compact deep learning model.

Self-hosted OSINT dashboard that fuses 60+ live intelligence feeds — flight tracking, ship AIS, satellites, CCTV, seismic and radio networks — into one real-time map, with an agent-ready command channel for AI co-analysts.
