Chromesthesia Review 2026: A Free Song Identifier Chrome Extension for Browser Tab Audio
VerifiedA free, open-source Chrome and Edge extension that identifies the song playing in your browser tab — no account or subscription required.

Chromesthesia 2026 Overview
Chromesthesia is a free, open-source browser extension for Chrome and Edge that identifies the song currently playing in any browser tab — no subscription, no sign-up for its default service, and no closed-source code to trust blindly. Built by a single independent developer, Mattias Wadman, and released under the MIT license, it works more like Shazam's old desktop tray tool than a SaaS product: click the icon, it listens to the tab's own audio, and it tells you the track.

What Is Chromesthesia and How Does This Song Identifier Chrome Extension Work?
Chromesthesia is a browser extension, not a website or an app — it only runs inside Chrome or Edge. Once installed, its icon stays dormant until a browser tab is actually playing audio. Click the icon while something is playing (a YouTube video, a Spotify Web Player track, an embedded podcast, a livestream) and the extension briefly captures that tab's audio, compresses it using the open-source "shine" MP3 encoder, and sends the clip to a music-recognition service to get a match. It is the same basic idea as Shazam, but scoped specifically to whatever a browser tab is already playing, rather than listening through a microphone to the room around you.
Who Needs a Free Shazam Chrome Extension Alternative?
- Browser-first listeners People who do most of their music and video listening in browser tabs (YouTube, Spotify Web Player, online radio) and don't want to pull out a phone just to identify a track.
- Privacy-conscious users Anyone who wants to avoid creating an account just to identify a song, and who prefers software whose source code they (or anyone) can actually read on GitHub.
- Researchers and content reviewers People who need to identify background music in a video, ad, or stream for sourcing or licensing checks, without leaving the tab.
- Budget-conscious users Anyone who just wants a working song-ID tool and has no interest in a subscription, a mobile app download, or an account wall.
Honest limitation: Chromesthesia only works on audio that's actually playing inside a browser tab. It can't identify a song playing from a speaker across the room, from a car radio, or from a different application — for that, a phone-based tool like the real Shazam app is still the better fit.
Chromesthesia Features: audD, ACRCloud, and AudioTag Song Recognition
audD — No Account Needed
The default recognition service. It works without creating any account and gives 10 free song lookups per day.
ACRCloud
A second recognition option you can switch to in the extension's settings. Requires a free account with ACRCloud itself.
AudioTag
A third option, also switchable in settings. Requires a free account with AudioTag.
Chrome and Edge
Published separately on both the Chrome Web Store and Microsoft Edge Add-ons, so it installs and behaves the same way on either browser.
Open Source (MIT License)
The full source is public on GitHub (wader/chromesthesia). The developer states in the README that the extension itself does not track usage or collect personal data — though the recognition service you choose may have its own data practices.
Music & Audio Recognition
Sits in our AI Music & Audio Tools directory alongside creation and editing tools like Klangio — though Klangio transcribes music into notation rather than identifying it.
How Much Does Chromesthesia Cost? Free, Open-Source, No Subscription
Chromesthesia itself costs $0. There is no premium tier, no in-extension purchase, and no subscription of any kind — the extension is free on both the Chrome Web Store and Microsoft Edge Add-ons, and its source code is published under the MIT license, so anyone can inspect or fork it for free as well. The only cost consideration is the recognition service behind it: audD (the default) is free with no account and a cap of 10 lookups per day; ACRCloud and AudioTag are also free to use but require creating a free account with that service directly, since Chromesthesia itself never charges anything.
| Service | Cost | Account Needed? |
|---|---|---|
| Chromesthesia (the extension) | $0 — always free | No |
| audD (default) | Free, 10 lookups/day | No |
| ACRCloud | Free plan available | Yes |
| AudioTag | Free plan available | Yes |
Where Chromesthesia Is Strong and Where It Needs Care
- Completely free and open sourceMIT-licensed, with the full source code public on GitHub — no hidden pricing, no ads to support a business model.
- No account needed for the default serviceaudD works out of the box with 10 free lookups a day and zero sign-up.
- Works on both Chrome and EdgePublished separately to both stores, so it isn't a Chrome-only tool.
- One click, no app switchIdentification happens from the extension icon in the same tab — no separate app, no copying a link anywhere.
- Only works on tab audioIt can't identify sound from a microphone, a speaker in the room, or a different app — only what a browser tab is itself playing.
- Two of three services need an accountACRCloud and AudioTag both require their own free sign-up if you switch to them.
- One independent maintainerSupport is through GitHub issues only — there's no company, help desk, or SLA behind it.
- Not available for Firefox or SafariChromium-based browsers (Chrome, Edge) only.
Real-World Use Cases for a Song Identifier Online and In-Browser
Identify a Track in a YouTube Video
Background music in a video essay, ad, or vlog with no caption — click the Chromesthesia icon while it's playing and get a match without leaving the tab.
Confirm a Track on Spotify Web Player
Useful when a playlist's metadata is wrong or missing and you want a second, independent source for the track name.
Source Music for Licensing Checks
Content reviewers identifying background music in a stream or ad for rights-clearance research, directly in the browser used to review the content.
Identify Music During a Livestream
Works mid-stream on Twitch or YouTube Live tabs, so there's no need to Shazam the audio through a phone's microphone instead.
How to Get Started With Chromesthesia
Install Chromesthesia from the Chrome Web Store or Microsoft Edge Add-ons — no account or payment step.
Play something in any tab — a YouTube video, a Spotify Web Player track, a livestream.
Click the Chromesthesia icon in the toolbar. It uses audD by default, with no sign-up required.
If a match fails or you hit the daily audD cap, switch to ACRCloud or AudioTag in the extension's options (each needs its own free account).
Is Chromesthesia Worth It in 2026?
For its one job — naming a song playing in a browser tab — Chromesthesia is hard to argue with: it's free, open source, needs no account for basic use, and does exactly what it says without trying to upsell anything. It won't suit anyone who wants to identify music from a speaker across the room or through a phone's microphone (that's a job for a mobile app, not a Chrome extension), and the two account-gated fallback services (ACRCloud, AudioTag) add a little friction if audD's 10-lookup daily cap runs out. For straightforward in-browser song identification, though, it genuinely delivers, and at $0 there's no real reason not to try it. By comparison, if you actually need to master or generate music rather than just identify it, LANDR and MusicGen are built for those different, paid-or-open-source jobs respectively.
Chromesthesia vs Shazam, AHA Music, and SoundHound
| Tool | Chromesthesia | How It Differs |
|---|---|---|
| Shazam (browser extension) | Open source, MIT license, no account | Shazam has been owned by Apple since 2018 and its results tie into the Apple Music/Shazam mobile app ecosystem rather than staying a standalone, auditable browser tool. |
| AHA Music | Source code public on GitHub | AHA Music is a closed-source browser extension; its code isn't publicly viewable the way Chromesthesia's MIT-licensed source is. |
| SoundHound | Browser extension, reads tab audio | SoundHound is a standalone mobile app from SoundHound AI, Inc. (a publicly traded company) built to recognize songs by humming or singing, not to read audio from a browser tab. |
The honest takeaway: Chromesthesia's real differentiator isn't recognition accuracy (it depends on the same category of third-party audio-fingerprinting services other tools use) — it's that it's free, open source, requires no account for its default service, and is scoped tightly to one job rather than bundling in a music app, a social feed, or an upsell.
Frequently Asked Questions
How much does Chromesthesia cost?
Chromesthesia is completely free. It has no paid tiers, no subscription, and no in-extension purchases — it's open source under the MIT license and free to install from the Chrome Web Store or Microsoft Edge Add-ons.
Do I need an account to use Chromesthesia?
No — the default audD recognition service works with no account or sign-up, giving 10 free song lookups per day. The two alternative services, ACRCloud and AudioTag, do require their own free account if you switch to them in the extension's options.
Does Chromesthesia work on Microsoft Edge?
Yes — Chromesthesia is published separately on the Microsoft Edge Add-ons store in addition to the Chrome Web Store, so it installs and works the same way on both browsers.
Does Chromesthesia track my data?
No — according to the developer's own GitHub documentation, the extension itself does not track usage or collect personal information, though the third-party recognition service you choose (audD, ACRCloud, or AudioTag) may have its own data practices.
Who makes Chromesthesia?
Chromesthesia is built and maintained by independent developer Mattias Wadman as an open-source project; the full source code is public on GitHub under the MIT license.
Key Takeaways
- Chromesthesia is a free, open-source (MIT) Chrome and Edge extension that identifies songs playing in a browser tab.
- No pricing plans exist — it's $0 forever, and the default audD recognition service needs no account (10 free lookups/day).
- Biggest strength is zero cost and zero sign-up friction; the main limitation is that it only reads audio already playing in a browser tab, not the room around you.
Alternatives to Chromesthesia: Other Song Identification Tools
- Shazam (browser extension) — Owned by Apple since 2018; ties results into the Shazam/Apple Music mobile app ecosystem instead of staying a standalone open-source extension.
- AHA Music — A closed-source browser extension; unlike Chromesthesia's MIT license, its source isn't publicly viewable.
- SoundHound — A standalone mobile app from SoundHound AI, Inc. built around humming/singing recognition, not browser-tab audio.
None of these are listed in our own directory, since they're not AI-generation tools in the sense most of our catalog covers. If you're instead looking for AI tools that create or manage audio rather than identify it, our Suno review covers text-to-song generation, Klangio covers AI music transcription, and Bridge.audio covers music catalog management — all different jobs from what Chromesthesia does.
Bottom Line: Chromesthesia does one job — naming the song playing in a browser tab — for free, with no account needed and an open-source codebase behind it. It's not a Shazam replacement for identifying music out in the real world, and it depends on a single independent maintainer rather than a company, but for in-browser song identification it's a genuinely useful, zero-cost tool.
