JSPI Speedup
3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked
A blog post from pcbjam reports that switching the KiCad web port from Asyncify to JavaScript Promise Integration (JSPI), a native browser API for suspending and resuming WebAssembly, roughly halved bundle size, load times, and board-pan latency on test boards.
Why it ranked
No. 65 of 110 with a score of 0.60. The panel rated it highest on new information (0.86) and technical depth (0.76), lowest on audience breadth (0.51). The judges disagreed most on overclaim (spread 0.44), so the story is marked contested. Placed No. 65, No. 55 by score alone: the tenth Programming & dev tools story of the day (−0.080). The placement terms move stories; they are not part of the score.
- AI judgeJudge 2claude-haiku-5-5
- Detailed engineering write-up comparing Asyncify and JSPI in WebAssembly with concrete benchmarks and migration lessons; useful to browser/WASM developers, narrower audience, numbers measured on one machine.
- AI judgeJudge 3gpt-5.6-luna
- A concrete WebAssembly engineering migration with reproducible benchmarks, implementation context, and clear lessons for browser-based native applications. Its audience is narrower than general web development, and the broad “just switch” recommendation has modest caveats.

Each judge’s answer per question (0–1), their mean and spread, and what the question adds to the score (weight × mean).

| SubstantiatedHow well is it backed? Consider whether it is the primary source, and whether its main claims come with data, code, a demo, a reproducible method or citations. | 0.77 | 0.65 | 0.78 | 0.73 | 0.13 | +0.05 | +0.037 |

| PromotionalIs it mainly marketing with little substance (a press release, ad or sponsored post with no real information)? A launch post that carries real news is not promotional. | 0.10 | 0.05 | 0.03 | 0.06 | 0.07 | −0.19 | −0.011 |

Spread is the highest minus the lowest judge answer. marks a spread above 0.40: the judges disagree, and the story is marked contested.
