About TechCompare
TechCompare is a free collection of browser-based tools for working with displays, hardware, storage, color, code, and security. Every calculator, converter, and visualizer runs entirely inside your browser. No accounts required, no installs required, and nothing you type leaves your machine.
Who runs TechCompare
TechCompare is a one-person project. I started it because I couldn't find a clean monitor curve comparer anywhere. The Curved Monitor Visualizer is still here, and the rest of the site grew up around it.
Honestly, most of these questions have an answer somewhere on the internet already. What TechCompare tries to do is give you the answer and a tool in the same place. You don't have to scroll through a blog post to find the number you came for, and you can plug in your own values instead of trusting someone else's example.
The other thing the answer rarely gives you is a picture. A number like "1500R curvature" or "21:9 aspect ratio" stops being abstract once you can actually see it next to the thing you're comparing. Most tools here ship a visualizer alongside the math, and a lot of them came from running into an edge case the existing sites couldn't be bothered to handle: a 49-inch ultrawide at 32:9, a 1000R panel seated 60 cm away, two RAID layouts with the same capacity but different fault tolerance. Off-the-shelf answers tend to assume a normal case. This site tries to answer the weird ones too.
I keep building it because it's a fun way to learn SEO and shipping small useful things. Each tool targets one specific question. If a tool needs to do three unrelated jobs, it probably should be three tools.
How the tools stay accurate
Every calculation is verified at build time, not at runtime. The same pure calculation functions that power the interactive tools also pre-compute the answers baked into the programmatic landing pages. So the H1, meta description, and visible stats on a landing page always reflect the real answer, not a template string someone wrote once.
A dedicated verification script (scripts/verify-landings.mjs) runs as part of the build. It re-runs every featured calculation and checks the output matches the numbers quoted in the landing page copy. If a calculation drifts, the build fails instead of shipping a page with a wrong answer.
Comparison pages are written per topic, not template-generated. Spec tables are data-driven so the numbers stay accurate, but the intro, context, verdict, and per-side recommendations are written individually for each slug. It's slower than spinning up a template, but it keeps every page genuinely different.
Spotting something wrong
If a calculation looks off, a spec table has a wrong number, or a piece of prose doesn't match reality, the quickest way to reach me is the Discord server. I read it and I fix things I can verify.
A heads up on pricing comparisons. Numbers like LLM API costs change often and I do not always catch the updates right away. Always check the provider's official pricing page before you make a decision based on anything you read here.
Privacy
Almost every tool runs entirely inside your browser and never sends your inputs anywhere. A few features talk to a server, and anonymous, aggregated analytics help me see which tools people actually use. Full details are in the privacy policy.
