Mantis Bug Tracker: Keep It or Use Something Lighter?
Mantis Bug Tracker, usually called MantisBT, is a free, open source, web-based bug tracker written in PHP that you install on your own server. It is a solid choice when you want a classic issue tracker under your control at no license cost. For a solo founder, the questions are whether you want to run another server, and how your users will report bugs into it, since they will not have MantisBT accounts. This guide covers both, and the lighter options if MantisBT is more than you need.
A note before we start: Indiehacker Studio, the product behind this blog, is not a bug tracker. It collects bug reports from users and sits in front of whatever tracker you use.
What is Mantis Bug Tracker?
MantisBT is one of the long-running open source bug trackers. It runs on PHP with a database such as MySQL or PostgreSQL, and you reach it in the browser. The typical setup is self-hosted, and there is also MantisHub, a commercial hosted version, for teams that do not want to run the server.
What it gives a small team:
- Issues with the classic fields: summary, steps to reproduce, severity, priority, status, assignee.
- Projects and access levels, so reporters, developers and managers see different things.
- Email notifications when issues change.
- Custom fields and plugins when the defaults are not enough.
What does self-hosting MantisBT cost you?
The software is free; the time is not. Running it yourself means:
- A server, plus PHP and a database, kept up to date.
- Backups, because the tracker becomes the memory of your product.
- Upgrades, including the security fixes a public web app needs.
- Email delivery, so notifications actually arrive.
For a team that already runs servers, that is a small job. For a solo founder whose product runs on a platform that hides servers, it is one more system to look after. MantisHub removes that work in exchange for a subscription.
What are the lighter alternatives to MantisBT?
| Option | Good for | Trade-off |
|---|---|---|
| MantisBT, self-hosted | Control and no license cost | You run the server |
| MantisHub | MantisBT without the server | A paid subscription |
| GitHub or GitLab issues | Code and issues in one place | Users need an account to report |
| Jira | Workflows, reports and integrations | More setup than a small team needs |
| A list in your notes | One person, a few open bugs | No history or search to speak of |
Bug tracker for small teams walks through the choice in more detail, and Jira bug tracking for small teams covers the Atlassian side.
Can your users report bugs into MantisBT?
Only if you give them accounts, or open anonymous reporting on a public instance. Both are awkward for a product with customers. Your users are on your site, not on your tracker. A separate login, a form full of fields they do not understand, and a page that looks nothing like your app all mean fewer reports.
What works better is a bug reporting tool inside your own app. The user writes one sentence, and the page URL, browser, viewport and an optional screenshot come with it. You read the report, reply to the user, and file the real bugs in MantisBT yourself, already with steps and context.
How do you keep MantisBT useful with a small team?
If you keep MantisBT, keep it small:
- One project per product, not per feature.
- Few statuses: new, confirmed, in progress, resolved.
- Severity that means something: does it block payment or the core feature?
- A weekly pass to close what you will not fix and merge duplicates.
- Only confirmed bugs go in. Questions and ideas stay in your support inbox.
A tracker with fifty fresh, real issues is more useful than one with five hundred stale ones.
How does Indiehacker Studio work with MantisBT?
Indiehacker Studio is the intake in front of MantisBT. One script tag adds a bubble to your site with a “Report a bug” tab next to live chat and in-app feedback. Every report includes the page URL, browser, OS and viewport, and recent console errors when you turn that on. On Pro, users can add a screenshot, a screen recording of up to 60 seconds, or up to three files.
Reports from all your projects land in one real-time inbox. You answer the user there and copy the confirmed bugs into MantisBT. There is no direct MantisBT integration today, so that step is manual, but the report already has what the issue needs.
The same script also gives you cookieless analytics, so you can see how many people visited the page where a bug was reported.
FAQ
Is Mantis Bug Tracker free?
MantisBT is open source and free to self-host. MantisHub, the hosted version, is a paid service.
Is MantisBT still a good choice?
For a team that wants a self-hosted, classic bug tracker and is fine running a PHP app, yes. If you do not want a server to maintain, a hosted tracker or your code host’s issues is simpler.
Can customers submit bugs to MantisBT without an account?
Only if you enable anonymous reporting on a public instance. Most products collect reports in their own app instead and file them in the tracker.
What is the difference between MantisBT and a bug reporting widget?
MantisBT organizes the work of fixing bugs. A reporting widget collects bug reports from users, with context, and feeds the tracker.
Does Indiehacker Studio replace MantisBT?
No. It replaces the email back-and-forth before a bug reaches MantisBT, not the tracker itself.
