ChiefOnboarding is an open-source employee onboarding platform that turns a new hire's first weeks into a guided sequence of tasks, reading, introductions, and small wins delivered through a web portal and a Slack bot. Onboarding starts before day one: send pre-boarding pages that welcome people, collect their details, and build excitement ahead of the first morning. Inside, to-do items carry the forms and information each hire must complete, and the portal tracks every item until it is done. Sequences drip-feed content over time or unlock the next step when a to-do is completed, so nobody opens thirty tasks on Monday morning. Resources build a searchable knowledge base with courses that bring hires up to speed on tools, processes, and team lore. Introductions put names and faces to the people a hire will work with, and badges reward finished milestones to keep momentum high. Behind the scenes, integrations provision user accounts automatically and fire webhooks into the rest of your stack when milestones land. Admins get their own to-do lists for laptops, access, and paperwork, coordinated with colleagues in the same timeline. The portal speaks eight languages, adjusts message timing to each hire's timezone, and wears your logo, colors, and email templates so the whole journey feels like your company, not a vendor tool. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
