Relaticle
The Next-Generation Open-Source CRM Platform written with Laravel
Relaticle is a self-hosted knowledge graph and note linking platform designed to help users organize, connect, and explore ideas in a visual and intuitive way. It blends the simplicity of a note-taking system with the power of a graph database, allowing users to create nodes for concepts, link them through relationships, and navigate their thoughts like a map instead of a linear document. The interface lets you write plain text notes and tag or connect them dynamically, making it easier to uncover patterns and connections over time instead of losing insights in a long, unstructured list. Because it’s built with productivity and exploration in mind, Relaticle offers fast search, semantic context awareness, and the ability to zoom from high-level overviews down to specific node details. It also supports self-hosting so users retain full control over their data without relying on third-party servers or cloud subscriptions. -

We’ve packed Twenty with powerful features to give you full control and help you run your business efficiently. Contribute, self-host, fork. Break free from vendor lock-in and join us in shaping the open future of CRM. The days when the role of CRM platforms was to shift manual data entries to a database are over. Now, the data is already there.
