Blastrunner
A minimal endless-runner front-end is practical for a single developer to build and host (prior open-source runner and game engines exist), so self-building is reasonable unless you need commercial polish, analytics, or monetization integrations.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Blastrunner alternatives, with the arithmetic →
What a replacement has to do
- Player controls a character that dodges obstacles and collects boosts to gain altitude; score increases over time and with pickups.
What it still won’t have
- Polished art, animations and sound assets that a commercial studio would provide
- Cross-platform publishing polish (stores, wrappers, automatic builds)
- Any proprietary analytics, AB testing, or monetization integrations
- Large-scale QA, device compatibility testing, and marketing
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Blastrunner does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a single-player endless-runner web game using Phaser 3 (or PixiJS) + TypeScript. Core features in scope: browser canvas rendering, a continuous upward-scrolling level, player controls (boost/jump), obstacle and pickup spawning with collision detection, scoring and localStorage high-score, simple start/pause/game-over UI, responsive layout, asset pipeline (sprites/sounds) and deployment as a static site on Netlify or Vercel. Out of scope: server-side leaderboards, in-app purchases, ad integrations, multiplayer. Include error handling, build scripts, unit tests for game logic (spawn, collision, scoring), and a README with deployment steps.
How we checked
How the score was reached
- Build verdict base78
- An open-source build was found+5
- 3 cited sources+3
- Evidence score86
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
