Tom's Planner

Tom's Planner is a browser-based Gantt chart tool that's been around since 2007 and doesn't require downloading anything. You drag tasks onto the timeline, set dependencies to show which work blocks other work, add milestones, and apply one of over 200 built-in templates for common project types. The interface stays lightweight and focuses on the core scheduling experience.

It's a solid choice for project managers and coordinators who need basic to intermediate timeline planning without the overhead of enterprise project management suites. The template library and zero-installation approach appeal to teams that need a quick start and don't want vendor lock-in.
