CRM
An open-source, agentic-first CRM
CRM is an open-source, agentic-first customer relationship management system built around a durable research agent. The agent operates on its own schedule and work queue, investigates contacts and companies, records supported facts, and schedules future checks. Rather than guessing personal details, it prices evidence and writes strong observations while sending weak evidence to a human for resolution. The interface manages contacts, companies, deals, tasks, pipeline views, and agent activity. Email threads, meetings, signature blocks, optional web research, and enrichment services can provide evidence. Durable sessions survive reloads and deployments, while a restricted sandbox prevents direct database access and network egress. The project is single-tenant and uses Google sign-in with an environment-based allow list. -

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. -
