About Codédex and inputprobe DPI Test

In their own words, as submitted to SaaSHub.

Codédex
inputprobe DPI Test

No description of Codédex yet.

A browser can't ask a mouse for its DPI, so this test measures it: drag along an object whose size is fixed by international standard (a bankcard is 85.60 mm by ISO/IEC 7810), three passes, median plus spread. Accuracy bands are published from 51 runs on real hardware, and an alignment check...

Features and specs

What each product offers, as listed by its team.

Codédex 4 features
inputprobe DPI Test 5 features
  • User-Friendly Interface
    Codédex offers a clean and intuitive interface that makes it easy for both beginners and advanced users to navigate and utilize the platform effectively.
  • Comprehensive Resources
    The platform provides a wide range of coding resources and tutorials, covering various programming languages and technologies, which are beneficial for learners at different levels.
  • Interactive Learning
    Codédex incorporates interactive coding exercises that enhance the learning experience by allowing users to practice and apply what they’ve learned in real-time.
  • Community and Support
    The platform fosters a strong community where users can interact, seek help, and share knowledge, complemented by responsive customer support.

Possible disadvantages

  • Limited Free Content
    While Codédex does offer some free resources, the majority of its more advanced tutorials and features require a paid subscription, which might not be accessible for everyone.
  • Occasional Technical Issues
    Some users have reported experiencing technical glitches or downtime, which can hinder the learning process if not addressed promptly.
  • Inconsistent Content Updates
    The frequency of content updates and new course additions can be inconsistent, potentially leaving learners waiting for new material in their areas of interest.
  • Overwhelming for Beginners
    Due to the extensive amount of resources available, beginners might find the platform overwhelming and struggle to know where to start.
  • Measures, does not guess
    A browser cannot ask a mouse for its DPI, so this measures it: you drag the mouse along a reference object of known size and it counts the movement the mouse actually reports over that distance.
  • Standard physical references
    Measure against a bank card, whose long edge is 85.60 mm by ISO/IEC 7810, or A4 or US Letter paper at 297 mm and 279.4 mm. The reference is an international standard, so no ruler is involved.
  • Three passes, median and spread
    You get the median of three passes plus the spread between them. Passes landing within a percent or two mean the measurement was repeatable; a wide spread means something interfered, and the tool says so.
  • Refuses rather than guesses
    When the three passes disagree, no DPI figure is reported. An honest refusal is more useful than a confident wrong number, and the page explains what to change before trying again.
  • Free, local, nothing uploaded
    Free and runs entirely in your browser. No account, no signup, no install, and nothing about the measurement leaves your machine.

Questions & Answers

As answered by people managing Codédex and inputprobe DPI Test.

How would you describe the primary audience of your product?

inputprobe DPI Test's answer:

PC gamers dialing in sensitivity who want to know their real DPI rather than the nominal number on the box, mouse enthusiasts (the r/MouseReview crowd) comparing sensors and verifying units, and anyone troubleshooting a mouse that "feels wrong", since a few percent of unit-to-unit sensor variance is normal and measurable. More broadly, anyone who prefers a measurement with a stated error band over a confident guess.

What makes your product unique?

inputprobe DPI Test's answer:

Two things. First, it measures instead of guessing: a browser cannot ask a mouse for its DPI, so the test divides raw movement counts by the length of an object that is exact by international standard, every bank card on earth is 85.60 mm long (ISO/IEC 7810), and paper sizes are fixed by ISO 216. Second, it publishes its own error bars. The accuracy bands shown next to your result were measured over 51 complete runs on real hardware (results on A4 stay within ~3% of each other, on a bank card within ~6%), and when a capture can't support a number, the test refuses to print one and tells you why, rather than averaging a mess into a confident-looking figure.

Why should a person choose your product over its competitors?

inputprobe DPI Test's answer:

Most online mouse testers measure your monitor, not your mouse: they count one movement per drawn frame, so results are quietly capped by your display's refresh rate. inputprobe reads the individual device reports with their own timestamps, before that distortion happens. It also handles the errors other testers ignore: it detects OS pointer acceleration instead of blaming your mouse, uses displacement so your drag doesn't need to be straight, and includes an alignment check that solves for your placement error, the one mistake repeatability checks structurally cannot see. And everything runs locally in your browser: no account, no upload, no tracking.

What's the story behind your product?

inputprobe DPI Test's answer:

I tested my own mouse on the popular online testers and got answers that were confidently wrong, most of them were really measuring my monitor's refresh rate. So I built a set of testers around one rule: a verdict must quote the evidence it's based on, and when the evidence isn't good enough, the tool refuses to print a number. That meant doing the unglamorous part: running the DPI method 51 times across two mice to measure how accurate it actually is, publishing those bands next to every result, and writing up the full methodology (including what has not been validated yet) at inputprobe.com/methodology/.

Which are the primary technologies used for building your product?

inputprobe DPI Test's answer:

Plain-vanilla web platform, no frameworks: the measurement engine is dependency-free JavaScript ES modules. The site is static HTML generated by a small Python build (Jinja2 + Markdown), served from Cloudflare's edge. There is no backend at all, every measurement runs entirely in the browser and nothing is uploaded.

Who are some of the biggest customers of your product?

inputprobe DPI Test's answer:

None to list, it's a free tool with no accounts and no tracking, so we genuinely don't know who uses it, and we prefer it that way.
