Automating mathematical box packing for web layouts: SKIP, 35/100 | Ideas Lab

A performance library that solves 2D bin packing for web layouts, replacing slow JavaScript implementations with optimized algorithms.

The pain

Web developers building image galleries, dashboard grids, or dynamic layouts manually implement or use slow bin packing solutions. JavaScript implementations cause layout jank and slow rendering on large datasets. CSS Grid and Flexbox don't solve irregular packing problems.

The gap

No standard, performant library exists for web-based 2D bin packing. Developers either accept poor performance, use server-side solutions (adding latency), or build custom implementations (time-consuming). Native solutions (WebAssembly) are underutilized in this space.

Build angle

Ship a WebAssembly-based bin packing library with a simple JavaScript API. Target specific use cases first: Pinterest-style layouts, dashboard widget placement, or image gallery optimization. Measure against baseline performance (current JS implementations). Charge per-seat or usage-based licensing to dev teams.

Strengths

Clear technical problem with measurable performance gains (can benchmark against existing solutions)
Specific developer audience with known pain point (layout performance)
WebAssembly approach is technically sound and differentiates from pure JavaScript
Low distribution friction if positioned as drop-in library

Risks

Narrow use case, most developers solve this with CSS Grid/Flexbox or accept current performance
Unclear if performance bottleneck is actually bin packing or other rendering issues
No evidence developers are actively searching for this solution or willing to pay
Competitive threat from free open-source implementations once proven valuable
Requires validation that this is a top-3 pain point for target developers, not a nice-to-have

Fly Labs Method

Is the pain real, is there a gap, is it the right time, can one person build it.

BreezePDF – Free, in-browser PDF editor

BreezePDF lets you edit, sign, merge, compress, redact, OCR, fill forms, extract tables, and use 30+ more PDF tools — all in the browser, no sign-up. Files never leave your computer.I built it because when people search Google for common PDF tasks, many of the tools they find upload documents to a server. I wanted an option that keeps files local instead.I posted an earlier version on HN last spring: https://news.ycombinator.com/item?id=43880962At the time it only supported a small set of features. Over the last 10 months I rebuilt large parts of it and expanded it to nearly 40 tools, including several ideas that came from comments in that earlier thread.There is also now a desktop app for macOS, Windows, and Linux, plus a CLI/SDK for developers.
