Gantt chart layer for Asana projects and standalone use.
3 hand-curated alternatives from MintedSaaS's directory. See the Instagantt listing →
Instagantt is a Gantt chart tool that layers onto Asana projects or runs as a standalone timeline planner. It's built for teams that want visual project scheduling without leaving their existing Asana workspace, or for companies that need basic Gantt functionality without the overhead of a full project-management suite. Instagantt sits in the middle of the market: more visual than a spreadsheet, less expansive than enterprise tools like Microsoft Project.
Teams reach for Instagantt when they need quick Gantt views of task dependencies and timelines, especially if they're already deep in Asana. They'll use it to drag milestones across a timeline, adjust resource allocation, and share a read-only Gantt view with stakeholders. It suits small-to-mid-size teams working on straightforward projects where the Gantt chart is the primary planning artifact, not one of many reports. If you're comparison-shopping alternatives, you're likely evaluating whether Instagantt's tight Asana integration and simplicity match your workflow, or whether a more feature-rich platform would better support your planning needs.
Spreadsheet-style project and work management at scale.
Online Gantt chart software for planning and tracking work.
Drag-and-drop Gantt chart tool for project schedules.
Smartsheet, GanttPRO, and TeamGantt are the most direct alternatives. Smartsheet offers enterprise-level flexibility and integrations; GanttPRO is a standalone Gantt tool with strong resource management; TeamGantt emphasizes collaboration and is simpler than Smartsheet but more capable than Instagantt.
GanttPRO offers a free tier with up to three projects, and TeamGantt has a free plan for basic timelines. Both are more limited than their paid versions, but they're suitable for testing before committing.
Smartsheet and GanttPRO work as standalone web apps; TeamGantt is browser-based and integrates with Slack, Google Drive, and other tools. None of them are as tightly coupled to a single project-management platform as Instagantt is to Asana.
Start by deciding whether you need a standalone tool or something that integrates with your existing project-management software. Then check whether the tool supports your team size, resource-allocation needs, and stakeholder-sharing requirements.
Most Gantt tools export to PDF or Excel for sharing with stakeholders. Smartsheet and TeamGantt both support scheduled exports and API access for deeper integration.
All three alternatives support remote teams through cloud-based interfaces and permission controls. Smartsheet and TeamGantt offer stronger collaboration features like commenting and version history; GanttPRO is simpler but still effective for distributed teams.
GanttPRO and TeamGantt are designed for rapid setup with minimal training. Smartsheet has a steeper learning curve but offers more power for complex workflows once learned.
Instagantt is the only dedicated Asana overlay. If you want to leave Asana, Smartsheet, GanttPRO, and TeamGantt all support importing tasks from Asana, but they don't maintain a live connection.
