Password manager

KeeWeb

A self-hostable web and desktop client for KeePass kdbx vault files — not a sync server. You host a single-page app behind your own domain and point it at a vault stored on local disk, WebDAV, or a cloud drive, so there is no database and no account system to run.

Project Management

Leantime

Open-source project management platform built for non-traditional project managers and neurodivergent teams, combining task/kanban boards, Gantt-style milestones, sprints, time tracking, and a project wiki. The self-hosted AGPL-3.0 open-source edition ships the full core project-management feature set plus white-labeling, client management, and LDAP/OIDC login for free; recurring tasks, custom fields, whiteboards, AI-assisted status updates, and program/portfolio-level strategy tools are paid plugin-bundle or Pro-tier add-ons and aren't part of the free self-hosted build.

Odoo

Odoo Community Edition is an open-source ERP suite — invoicing, inventory, manufacturing, CRM, employees and website/e-commerce are all separate apps within one platform, with CRM as just one of those modules rather than a standalone product (full Accounting and Payroll are Enterprise-only). Odoo also sells proprietary Enterprise modules and managed hosting; only the LGPL-3.0 Community Edition is covered here. It runs on the official Docker image with a PostgreSQL backend.

Project Management

PLANKA

Kanban board for teams and personal projects, with projects, boards, lists, cards, labels, due dates, attachments, comments and real-time updates.

PrivateBin

A minimalist pastebin where pastes are encrypted and decrypted in the browser with 256-bit AES, so the server has zero knowledge of the pasted data. Supports expiring and burn-after-reading pastes, discussions and optional file uploads.
