I built a Project Management and Timeline / GanttChart App

project-timeline.com I wasn't happy with traditional Gantt charts, I think they are too big and technical for putting onto slides and showing projects. So I started building a tool that shows them in a more consolidated way. After a few months and 100+ iterations I built a full project management tool, with resources, built in AI, etc. All fully customizable. I work as a mechanical engineer and program manger, and had used GanttProject for years. With the power of Claude Code, I thought I would make a more modern web based version. Check it out! I'm looking forward to critical feedback too! What it does Gantt and timeline views that you edit directly on the chart: drag bars, draw dependencies Critical path, milestones, delays, baselines, working calendars with public holidays Resources with allocation %, an over-allocation chart, and cost totals Export to SVG, PNG or vector PDF sized for a slide, so it stays sharp when someone zooms in Imports MS Project XML, GanttProject (.gan) and CSV A built-in AI assistant: “push launch two weeks and move everything after it” reworks the real schedule, dependencies included Read-only share links that need no account to open Templates for website launch, product development, software release, events and hardware Available in English, French, German, Italian, Dutch and Spanish Pricing: free in the browser, no sign-up. Pro is €3.99/month: no watermark, sharing, more AI requests, and Jira sync, where Claude, ChatGPT or Grok brings in the Jira epics you choose and writes your planned dates back to Jira. What it isn’t: a full MS Project replacement. It has finish-to-start links only and no resource levelling. If you schedule for a living, you probably need the heavy tool. Stack: a single-page vanilla JS app (no framework), Supabase for accounts and sync, Netlify, Stripe. What I’d love feedback on: In the first 30 seconds, was it clear what to do? Did the exported chart look good enough to put in front of your boss? What made you close the tab? Happy to answer anything about how it’s built.   submitted by   /u/Original-Key5167 [link]   [comments]
