2 entries in this register are declared substitutes for, successors to or predecessors of deviceinfo.me, and all of them are still shipping at the last field check. deviceinfo.me itself reads DEAD. Every row in the table below is judged by the same rubric, from the same sweep, on the same fields — this page ranks nothing and recommends nothing, because a register that has measured no population is in no position to.
Every row below is judged by the same rule as deviceinfo.me itself, from the
same field check. Supersession is only printed where a project or its
author says so — this register does not infer that one tool replaces
another because it is newer.
Read the state column with the licence column. A permissively licensed
project that stopped shipping is not safer than a copyleft one that did
not.
What deviceinfo.me does, so you know what you are replacing
Formerly a broad attribute dump of the kind section 03 is full of, cited across older guides as a one-stop readout.
A substitute has to do that job, not merely occupy the same category. The host did not complete a connection at this field check, so there is nothing to read there now. It is kept in the catalogue rather than deleted, because a dead entry with a status and a date is more useful than a quiet removal.
How this register decides what counts as an alternative
BrowserLeaks, Device and Browser Info are recorded as substitutes for the same job. The alternative relation is symmetric and carries no ordering at all: it says these things answer the same question, and it says nothing whatsoever about which answers it better.
Nothing on this page is a ranking, a score or a recommendation, and nothing on it is a detection-test result — no entry in this register has been run against any anti-bot system by this register. What the table gives you is four measured columns and one derived one, applied identically to every row.
How to read the comparison above
Every candidate reads ACTIVE or SEMI, so the choice here is genuinely about fit rather than about survival. Compare the release column rather than the push column: a project that pushes constantly and tags rarely asks you to depend on a branch, which is a different commitment from depending on a version.
Every entry in the table declares a licence, which is less common in this catalogue than it should be — the entries that declare none are grouped separately. Read the licence column beside the state column rather than after it: a permissively licensed project that stopped shipping is not a safer dependency than a copyleft one that did not.
One page per surface — canvas, WebGL, fonts, WebRTC — with the raw values rather than a verdict.

Why ACTIVE: No repository. The link check returned 200 at 2026-08-14T09:12:00Z, and 200–399 is ACTIVE for a non-repository entry.

Answered from the same fields the table above prints, and from no other source.
What is the best alternative to deviceinfo.me?
This register does not answer that, because it publishes no ranking and has tested no tool to rank. What it can tell you is which candidates are still shipping: BrowserLeaks, Device and Browser Info. The rest of the decision is fit, licence and how much of your own stack you are prepared to change.
Are these deviceinfo.me alternatives still maintained?
BrowserLeaks reads ACTIVE, Device and Browser Info reads ACTIVE. Each of those states is derived from that entry's own measured fields by the rubric in force, at the field check printed in the folio, and the clause that produced it is printed on the entry page.
Why does this list not rank the alternatives?
Because a ranking would be an opinion wearing a number's clothes. Every figure on this site is a date, a count, an SPDX identifier or an HTTP status you can re-fetch from the endpoint named beside it, and there is no honest way to compress those into an ordering without inventing weights nobody published. The rubric sets states; it does not rate them against each other.
Where does the alternatives data for deviceinfo.me come from?
From declared edges in the register itself, never inferred. Each edge is stored once and reversed at build time, and every field in the table is read from the same sweep that produced the rest of the catalogue. The whole set is downloadable as CC0 JSON and CSV, including the supersedes, superseded_by and alternative_to columns.
A test page tells you that something is inconsistent. It does not tell you which layer produced the inconsistency, and it will not fix it. Donut Browser is an open-source anti-detect browser under AGPL-3.0 that addresses the layer most of these pages are reading: engine-level fingerprint overrides through CDP rather than injected script, with a pre-launch gate that refuses to start a profile when the proxy's exit geography contradicts the profile's own fingerprint.
