One-Time Purchase.
Hosted by You.

Designed for intuitive use by developers, designers, and managers alike. Customize the logo and name to make it your own tool, easily deployed on standard hosting or any server of your choice.

Everything a project needs, nothing it doesn't.

Built to run real client work — from a single freelancer to a full agency team.

AI Integration (Claude API)

Paste in meeting notes or memos, and AI drafts tasks and comments for you.

AI-powered project management, even with a one-time purchase

GeckoFlag is one-time-purchase project management software, yet it supports Claude AI assistance for creating tasks, comments, projects and wiki pages.

You don’t need to switch to an expensive monthly plan to use AI.

Just connect your own Claude API key to get AI input assistance whenever you need it.

* AI usage fees are not included in the software price and are charged based on your API usage.

AI usage costs only a little, too

For example, generating a task description from meeting notes with Claude Haiku 5.5 is estimated to cost about $0.001–0.002 per use. Even 1,000 uses come to only about $1–2.

* This is an estimate based on specific input and output conditions. Actual costs vary with the length of the text you enter, the content generated, the model you choose and other factors.

Claude Integration

Search, create and update issues, or export Gantt charts to Excel, just by chatting with Claude.

Work in GeckoFlag just by asking

Simply ask things like “Comment on WEB-3 with what was done and mark it as done” or “Add the meeting notes to the wiki”, and Claude searches, creates and updates issues, projects, wiki pages and notes for you.

Export Gantt charts to Excel

Save a project’s issues to your computer as an Excel file, with parent-child relationships and a timeline.

Same permissions as on screen. No deleting

Everything runs with the user’s own permissions, and creating or changing data requires an administrator’s permission. Claude cannot delete any data.

* No additional charge from GeckoFlag. Requires the Claude desktop app (Windows, macOS) and a Claude plan. Screen shown is for illustration only.

A Message from the Developer

Hi, I'm the developer behind GeckoFlag.

Over the years, I've used countless project management tools — both as a hands-on team member and as a manager. Many of them were genuinely excellent, but in day-to-day use I kept running into the same frustrations:

  • Running costs that keep climbing every month as the team grows
  • Feature sets so extensive that non-engineers and decision-makers struggle to use them at all

"We rolled out a tool, but only a few people actually update it." "We ended up managing the tool instead of the project." GeckoFlag was built to put an end to those complaints.

I kept only the features teams actually need in practice, and focused everything else on making it simple enough for anyone to use, regardless of role. On top of that, it adapts flexibly to feel like a tool built in-house for your own team.

Whether you're still deciding or already using GeckoFlag, I personally read and respond to every inquiry — before and after purchase.

I hope GeckoFlag can be the partner that helps your team manage projects more smartly.
