Quick answer: A spreadsheet is fine while you're solo with a handful of bugs you found yourself. A bug tracker wins once players report bugs, because it auto-captures context, groups duplicates, and ranks by impact, things a spreadsheet fundamentally can't do. Switch when you feel that friction.
Spreadsheets are the default first bug tracker for many indies, free, familiar, zero setup. A dedicated bug tracker adds capture, grouping, and ranking. The right choice depends on your scale: a spreadsheet works small and solo, while a tracker wins once players and volume enter the picture.
When a Spreadsheet Wins
While you're a solo developer pre-launch with a dozen bugs you found yourself, a spreadsheet is genuinely adequate, you have all the context in your head, there are no duplicates to manage, and nothing needs ranking. It's free, instantly available, and infinitely flexible. Reaching for heavy tooling at this stage is premature.
So the spreadsheet's strength is simplicity at small scale. If your bug list is short and you're the only one adding to it, the overhead of a dedicated tracker may not pay off yet. Use the simplest thing that works for where you actually are.
When a Bug Tracker Wins
The moment bugs start coming from players, the spreadsheet breaks down. Reports arrive without context (you can't auto-capture device or version into a sheet), the same issue gets entered many times (no grouping), and you can't tell what's widespread (no impact ranking). You spend more time maintaining rows than fixing bugs.
A dedicated tracker automates exactly these jobs. Bugnet captures device and version context automatically, groups duplicate reports, and ranks by how many players are affected, the three things a spreadsheet fundamentally can't do, no matter how clever your formulas. At player scale, the tracker wins decisively.
How to Decide and When to Switch
The decision isn't ideological, it's about scale and friction. Use a spreadsheet while you're solo and small; switch to a tracker when you feel the pain: duplicates piling up, reports too vague to act on, no way to know what to fix first. That friction usually coincides with players starting to report and volume growing.
When you're spending more time wrangling the sheet than fixing bugs, the spreadsheet has become the bottleneck. Bugnet is built for that transition, taking over the capture, grouping, and ranking a spreadsheet can't. So start simple, but move to a tracker once player reports make the spreadsheet cost more than it saves.
Spreadsheet wins while you're solo with a few self-found bugs; a tracker wins once players report, it auto-captures context, groups duplicates, and ranks by impact. Switch when you feel that friction.
