Features and specs

What each product offers, as listed by its team.

inputprobe DPI Test 5 features
Better Stack 14 features
  • 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.
  • Logs & traces
    Aggregate structured logs & traces from anywhere, transform them with VRL and query using Drag & drop, simple filtering, PromQL or SQL.
  • Metrics
    Visualize metrics with ready-made collaborative dashboards. Generate metrics from logs or collect them via Prometheus, OpenTelemetry or others.
  • AI SRE
    Slack-native AI SRE agent that investigates incidents using your logs, metrics, traces, errors, and web events.
  • Error tracking
    Don’t waste time reproducing errors manually. We provide you with browser context, backend environment variables, and stack traces so you can focus on fixing.
  • Uptime monitoring
    The most reliable external monitoring for your monolith application, SPA, REST API, or a bare metal server.
  • Transaction monitoring (Playwright)
    Hosted Playwright-based transaction checks let you monitor vital website interactions by running a real browser instance.
  • Heartbeats (Cron job monitoring)
    Heartbeats let you monitor scheduled jobs like cron jobs or serverless workers. Never lose a database backup again.
  • On-call & incident management
    On-call scheduling & alerting is built-in. Set up duties, get flexible alerting options, and resolve incidents collaboratively.
  • Slack-based incident management
    Resolve incidents without leaving Slack by leveraging powerful automations.
  • Call routing
    Route incoming phone calls to the current on-call person to create incidents automatically.
  • Reporting & analytics
    Track team KPIs easily analyze incident metrics, on-call duties, and advanced SLAs/SLIs.
  • Status pages
    Get a branded status.yourdomain.com and build credibility with customers. Monitoring and incident management is fully-integrated.
  • Security
    Keep your data secure and control your costs by having visibility into your usage. Stay compliant with SOC 2, GDPR, and more.
  • Real user monitoring
    Session replay, web vitals & product analytics

Questions & Answers

As answered by people managing inputprobe DPI Test and Better Stack.

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.

Better Stack's answer:

Engineering teams of all sizes – from startups to Fortune 500 companies.

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.

Better Stack's answer:

Better Stack is a modern observability tool that leverages eBPF and OpenTelemetry to make tracing work for you.

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/.

Better Stack's answer:

We are software builders at Better Stack.

CEO is a software engineer, COO is a software engineer and you guessed it; CTO is an engineer, too.

We’re helping developers ship higher quality software faster.

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.

Better Stack's answer:

You get an unrivaled price-to-performance ratio. Forget sampling and ingest all your data, or decrease your costs by 30x.

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.

Better Stack's answer:

The primary technologies used to build Better Stack are eBPF for low-level, high-performance instrumentation and ClickHouse for storing and querying large volumes of observability data efficiently.

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.
