Design and diagrams decision
Lopaka.app
A small, focused web app that converts images to microcontroller-friendly formats is realistic for one capable developer to build and maintain; no durable moats are evident from the product page.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.
$50one-off30 h to build
$0/mo1 h/mo upkeep
No published price to break even against.
No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Import raster images → resize/crop/palette-reduce/dither → convert to microcontroller bitmap/array formats (Adafruit_GFX, u8g2, TFT_eSPI) → preview on simulated display → export as header/source files or binary blobs
What it still won’t have
- polish, QA and cross-platform installers
- broad device-driver coverage and edge-case testing for all supported libraries
- existing user documentation, examples and community support
- performance optimizations for large images
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Lopaka.app 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-page web app (React + Vite) that runs entirely client-side and converts images for microcontroller displays. Core features in scope: image upload (drag/drop, common formats), resize/crop, palette reduction and selectable dithering algorithms, converters that output Adafruit_GFX, u8g2, and TFT_eSPI compatible C/C++ arrays and header snippets, a preview canvas that simulates target display size/color depth, and export buttons producing .h/.c/.bin downloads. Out of scope: server-side rendering, cloud storage, billing, or user accounts. Include error handling for invalid files, unit tests for conversion functions, and end-to-end tests for the export flow.
How we checked
How the score was reached
- Build verdict base78
- 3/3 assessment runs agreed+4
- Evidence score82
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.
