baserow/baserow
4,188View on GitHubBaserow is a self-hosted, no-code relational database platform built on PostgreSQL. It provides a spreadsheet-like interface for structuring and managing data without writing code, while exposing all database resources via a REST API to support headless architectures. The platform distinguishes itself by integrating large language models and embedding servers to power AI assistants and automated data generation. It further extends its utility as a no-code application builder, allowing users to create custom internal portals, dashboards, and business tools using visual logic and managed data.
Baserow is a self-hosted, no-code relational database with a spreadsheet interface, REST API, and multi-user collaboration, and while it supports database views and automations, it lacks native Gantt/timeline project planning features, making it a strong match for the spreadsheet and database aspects but only a partial fit for the project planning requirement.
