Contacts, deals, and notes — all linked in one living graph. No more toggling between a CRM and a second brain. Self-hosted. Markdown-native. Yours.
Traditional CRMs store data. Nexus connects it. Every record becomes a node in your knowledge graph — and every note in your second brain becomes context for your deals.
Leads, contacts, companies, pipeline, activities, tasks — a complete CRM built for self-hosted teams. Kanban boards, list views, automated workflows. No per-user pricing.
Bidirectional links between notes, contacts, and deals. Backlinks show you every connection to anything. Graph view makes relationships visible — not buried.
Instant capture — no folders, no forms, no friction. Write a memo, link it to a contact, and it's instantly connected to everything in your CRM. Your workflow stays alive.
Every existing CRM treats notes as attachments. Nexus treats notes as the primary unit — every contact, deal, and company is a node in your knowledge graph, not a row in a spreadsheet.
No folder structure. No templates. Just write. A memo links to a contact — that contact instantly shows the memo in its backlinks. Your thoughts stay connected to your work, automatically.
Nexus is the open-source CRM that finally brings them together. Self-hosted, privacy-first, built for teams who think in connections, not just data.
