A free, open-source GoFullPage alternative — including Firefox
The short version: OpenCapture does the same core job — one click, whole page, PNG or PDF — and adds three things GoFullPage does not: a Firefox build, source code you can read, and blurring that is not behind a paid tier.
Note, September 2026: GoFullPage's original Chrome Web Store listing has been down since 10 August. GoFullPage says the removal was copyright-related and, in its own words, “not a security issue with GoFullPage”; an official BETA listing is live in the meantime. What happened, and every official link. The comparison below describes both products as they normally ship.

What actually differs
1. You can read what it does with your pages
Both extensions capture inside the browser. The difference is that with OpenCapture you don't have to take that on faith — the core extension is published under AGPL-3.0-or-later, so anyone can read exactly what it touches and what it sends. For an internal dashboard, a client’s admin panel or a medical portal, that is a different claim from “trust us” — and usually the one a security team asks for.
GoFullPage’s public repository is MIT-licensed but stops in 2018. The version that ships today is built from a private branch, so its source is not available to read.
2. A GoFullPage alternative that works in Firefox
GoFullPage ships for Chrome and Edge. The team has said it is working on a Firefox version, but none has shipped, so today, if any part of your work happens in Firefox, GoFullPage cannot follow you there.
OpenCapture ships the same Manifest V3 extension to Chrome, Microsoft Edge and Firefox from a single codebase, so the editor and the export options are identical wherever you are. If you work across two browsers, or your team is split between them, that's one tool and one set of muscle memory instead of two.
3. The paid line sits in a different place
In OpenCapture the one paid feature is watermarking — tiling a logo or text across an export — and it's a one-time Supporter unlock, not a subscription.
GoFullPage draws its line around the editor. Capturing a page and exporting it straight away is free; the moment you crop, annotate or blur and then export the edited version, that export needs a Premium subscription. So the free tier is a capture tool, and the editing is the product you pay for.
OpenCapture puts the line somewhere else entirely. The whole editor — crop, arrows, text, blur, unlimited undo — is free, and the only thing behind the paywall is tiling a watermark across an export. Watermarking runs the other way too: GoFullPage does not offer it at all. The structural difference is the billing — GoFullPage is a subscription, from $1 a month billed annually; OpenCapture’s single paid feature is a one-time unlock — $5 for 1,000 credits — that never expires.
Where GoFullPage is the better pick
It is the more established product: continuous releases since 2012, and an interface a lot of people already know. It also lets you try the paid tier before paying — there is a seven-day free trial. If you only use Chrome and it already does what you need, switching gains you very little.
OpenCapture makes sense if you want Firefox support, code you can read, or an editor that is not part of a subscription.

Install, click once, and you have the whole page. Nothing to sign up for, and nothing to cancel.
Questions people ask
Is there a free alternative to GoFullPage?
Yes. OpenCapture captures full pages, crops, annotates, blurs and exports to PNG or PDF at no cost. The only paid feature is watermarking, which is a one-time unlock rather than a subscription.
Is there a GoFullPage alternative for Firefox?
GoFullPage has no Firefox build today, and the team has said it is working on one, with no ship date given. OpenCapture ships the same Manifest V3 extension to Chrome, Microsoft Edge and Firefox from a single codebase, so the editor and export options are identical across all three.
Is OpenCapture open source?
The core extension is published under AGPL-3.0-or-later on GitHub, so its data handling can be audited by anyone. GoFullPage’s public repository is MIT-licensed but stops in 2018, and the version shipping today is not published. The optional watermark module in OpenCapture is proprietary.
Where are my screenshots processed?
Entirely inside your browser. The capture and editing code has no upload path, so a screenshot never leaves your device. Signing in is needed for exactly one thing: buying the watermark unlock, which is the only feature that talks to our server. Everything else works signed out.
Can OpenCapture export a full page as a PDF?
Yes. Any capture can be exported as a single PNG or a single PDF, including pages that are many screens long.
Do I need to uninstall GoFullPage first?
No. Both extensions can be installed at the same time. Pin whichever one you want in the toolbar and remove the other once you have decided.
