All Open Source Apps

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.

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.

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.

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.

The all-in-one, open-source backend platform purpose-built for AI coding agents — giving your agent database, auth, storage, edge functions, a model gateway, and compute to ship full-stack apps end-to-end.

Spreadsheet-like interface for your PostgreSQL database — self-hosted, no SQL required, native Postgres access control.

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

Open-source time-series database built for real-time ingest, fast SQL queries, and embedded Python automation — powered by Apache Arrow and Parquet.

Open-source desktop SQL workspace with built-in PostgreSQL, MySQL, and SQLite drivers, SQL notebooks, a visual query builder, and a built-in MCP server for AI agents like Claude and Cursor.

Fast, stable Redis GUI with cluster, SSH, and massive key support

Self-hosted database backup manager with a web UI for scheduling, encrypting, and restoring MySQL, PostgreSQL, MongoDB, SQL Server, SQLite, Firebird, and Redis to S3, SFTP, Samba, or local storage.

The AI Workspace for Finance: Connect Data, Run AI Agents, Build Analytics

A single graph+vector+temporal database for AI workloads — Neo4j-compatible, sub-millisecond hybrid search, and built-in memory decay.

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

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

A native macOS, Windows, and Linux database IDE for PostgreSQL, MySQL, SQLite, Redis, MongoDB, SQL Server, and ClickHouse, with a built-in MCP server and AI chat that reads your schema.

API-first collaborative spreadsheet-database platform that auto-generates REST APIs and lets teams build internal tools, CRMs, and dashboards without code.

Federated AI search and RAG across 100+ enterprise sources—no data extraction, no vector database required.

A RocksDB-based NVMe/S3 cache purpose-built for AI inference workloads — a faster Redis replacement optimized for batch, low-latency, zero-copy reads and writes between data pipelines and inference apps.

Morphik is an AI-native ingestion and retrieval engine that lets developers store, search, and reason over visually rich documents — scanned PDFs, manuals, slides, and video — without duct-taping together OCR, an embedding model, and a vector database.

An open-source MongoDB alternative that translates wire protocol queries to SQL and stores documents in PostgreSQL

Self-hostable personal finance app that gives you full ownership of your financial data with a clean, minimal Rails-powered interface.
