Quick answer: For a Pygame game, Bugnet is the most game-aware option: a pip-installable SDK with no extra dependencies that captures uncaught exceptions with a screenshot of your display surface, adds an in-game report widget and freeze detection, and puts it all in a tracker. Sentry, Rollbar and Honeybadger are excellent Python error monitors built for web services. For a hobby project, sys.excepthook plus faulthandler writing to a file costs nothing.
Python has some of the best error tracking in any language, because so much of the web runs on it. Pygame games are a different shape: a frame loop, a window with no console once you package it, and players who will not send you a traceback. Here is how the options compare for Python games in 2026.
What a Pygame game needs
- Capture without a console. Once you package with a tool like PyInstaller as a windowed app, tracebacks printed to stderr go nowhere. Errors must be caught and sent.
- A picture of the screen. The display surface at the moment of the error explains more than the traceback.
- Freezes as well as exceptions. A stuck loop never raises.
- Player reports. Most game bugs do not raise exceptions at all.
At a glance
| Option | Install | Screenshot | Player reports | Built for |
|---|---|---|---|---|
| Bugnet | pip install bugnet-sdk (or one file); standard library only | Display surface, automatically on crash | Built-in widget drawn in Pygame | Games |
| Sentry | pip install sentry-sdk | No | Not built in | Web services and apps |
| Rollbar | pip install rollbar | No | No | Web services and apps |
| Honeybadger | pip install honeybadger | No | No | Web services and apps |
| Standard library | Nothing to install | Your code | No | Anything |
Bugnet
Bugnet's Pygame SDK supports Pygame 2.x on Python 3.8+ and uses only the standard library (an optional extra adds memory reporting). bugnet_sdk.init(api_key, server_url) installs an exception hook, so an uncaught exception is filed as a critical crash with the traceback and a screenshot of the current display surface. Pass events to bugnet_sdk.handle_event(event) and call bugnet_sdk.update(screen, clock) each frame to draw the report widget and enable freeze detection; open the widget with bugnet_sdk.show_widget() on a key like F1.
Reports land in a tracker with grouping, crash-free sessions per build and integrations with GitHub, Discord and more; on Studio Plus, a short animated capture of recent gameplay is attached. See where Pygame crash logs go for the manual alternative. Free to start.
Sentry, Rollbar and Honeybadger
All three are mature Python error monitors: initialise them at startup and uncaught exceptions are reported with tracebacks, local context and alerting. If your game has a Python backend already monitored by one of them, using the same tool for the client is reasonable. What they do not do is look at your screen, notice a frozen frame loop, or give players a form inside a Pygame window.
The standard library route
For a jam game or a hobby project, Python gives you the essentials for free. Set sys.excepthook to write the traceback to a log file in the user's data folder, and call faulthandler.enable(file=...) so hard crashes in native code (a segfault in a C extension, say) dump a traceback too. You then have to ask players for that file, which most never send. That is the gap a hosted tool closes.
Which should you pick?
- A Pygame game you are shipping to players: Bugnet.
- A game with a Python backend already on Sentry, Rollbar or Honeybadger: that tool for consistency, plus a player report form.
- A jam or learning project:

Frequently asked questions
How do I track errors in a Pygame game?
Install an SDK that hooks uncaught exceptions and sends them with context. Bugnet's Pygame SDK does this with a screenshot of the display surface, an in-game report widget and freeze detection, using only the standard library.
Can I use Sentry with Pygame?
Yes. Sentry's Python SDK captures uncaught exceptions in any Python program, including Pygame games. It does not capture screenshots or provide an in-game report form.
Why do I not see errors from my packaged Pygame game?
A windowed build has no console, so tracebacks printed to stderr are lost. Use an exception hook that writes or sends them, such as a custom sys.excepthook or an error tracking SDK.
What is faulthandler for?
Python's faulthandler module dumps Python tracebacks when the process crashes hard, for example on a segmentation fault in native code, which a normal exception hook cannot catch.
Does Bugnet's Pygame SDK have dependencies?
No. It uses only the Python standard library. An optional extra adds memory usage reporting.
Python will tell you exactly what went wrong. The trick is making sure it tells you, not the player's closed terminal.
