Quick answer: A demo is a polished public slice meant to sell the game; a beta is a testing phase meant to find bugs. One is marketing, the other is QA, though both put your game on real players.
Demos and beta tests both let players experience your game before full release, but their purposes are opposite: a demo sells, a beta tests. Confusing them leads to mistakes, like shipping a buggy demo or treating a beta as a marketing moment. Here's how they differ.
What a Demo Is For
A demo is a polished, public slice of your game meant to convince players to buy. It's marketing: it shows the game at its best to drive wishlists and conversion, and it needs to be stable and representative, because a buggy or unflattering demo actively hurts sales.
Because a demo is public and sells the game, polish is non-negotiable. Bugnet captures crashes from demo builds, which matters because a demo doubles as a large-scale test, but its primary job is conversion, so it must make a strong first impression.
What a Beta Test Is For
A beta is a testing phase meant to find bugs before launch. It's QA: you give the game to testers specifically to surface crashes and issues on real hardware, and a rough build is expected, finding problems is the point, not hiding them. Betas are often more limited and less polished than demos.
Bugnet captures crashes and reports from beta builds with context, turning the beta into a structured source of fixes. Where a demo shows the game at its best, a beta deliberately stresses it to find what's broken, an opposite purpose despite the surface similarity.
How They Overlap and Combine
They overlap in that both put your game on real players and hardware, so a demo inevitably surfaces bugs too, if you capture them. The smart move is to treat your demo as a test as well as marketing, fixing what real players hit, while running an actual beta for focused bug-finding.
Bugnet captures crashes from both, so a demo hardens the game while selling it, and a beta finds bugs before launch. Rather than choosing, recognize a demo is for selling and a beta is for testing, use each for its purpose, and let your demo double as a real-world test by capturing what players hit.
A demo sells the game (marketing, must be polished); a beta finds bugs (QA, rough is fine). Opposite purposes, though both use real players. Many games use both, and a demo can double as a test.
