Developer tools decision
DevUtils
A single developer can build a useful subset (core formatters, encoders, clipboard detection) but reproducing the full native macOS polish, complete catalogue of 47+ tools, and the commercial packaging/license UX would be time-consuming; keep paying if you need the full product experience.

Not priced
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 DevUtils alternatives, with the arithmetic →
What a replacement has to do
- Open the local app, paste or capture clipboard content, run a selected converter/formatter/inspector, copy or save the result locally.
What it still won’t have
- Native macOS Cocoa performance and look-and-feel
- The full catalogue of 47+ prebuilt tools and ongoing one-year updates included in the commercial license
- Built-in license manager / purchase flow and license restore
- Polish integrations with macOS app ecosystem (Alfred, Raycast, Terminal) and maintained shortcuts
What remains hard
- Brand trust
🌏 Trusted by 10,000+ Productive Developers
- Execution quality
Native macOS app, fast & beautiful
First-year cost
No published price
DevUtils 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 local desktop toolbox app using Electron + React + TypeScript packaged for macOS. In-scope core features: (1) a left-side tool list and search with at least JSON Formatter/Validator, YAML↔JSON, CSV↔JSON, Base64 encoder/decoder, Hash (MD5/SHA256) generator, UUID generator; (2) clipboard watcher with a rule-based smart detection engine that suggests the right tool; (3) file import/export, copy result to clipboard, and local settings; (4) offline-only operation and no external network calls; (5) packaging for macOS (.dmg or signed installer). Out of scope: reimplementing all 47+ tools, native Swift/Cocoa UI, license/purchase flow, integrations with Alfred/Raycast. Provide error handling, unit tests for parsers/formatters, and a CI workflow that builds macOS artifacts.
How we checked
How the score was reached

- Price verified on pricing page+3
- 3/3 assessment runs agreed+4
- Evidence score67
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.
