Every website feedback tool does the same headline thing. Someone opens your site, clicks on the broken bit, types what is wrong, and the comment stays pinned to that spot. That problem is solved. Nine tools do it competently, which is exactly why choosing between them is harder than it looks.
Feature tables will not help you, because on the features that get listed, these tools are nearly identical. The thing that actually decides whether a tool works for you is almost never in the comparison table: how the tool gets itself onto the page in the first place. Get that wrong and the tool does not work on your project at all — not badly, just not at all.
One warning before the list. Search for this topic and almost every result on the first page is written by a company selling one of the tools, ranking itself at or near the top. This post is no exception — we build UX Peeker. So we have put our own entry near the bottom, written the part about where we are the wrong choice, and left prices out entirely. Judge the rest on whether it helps you rule things out.
Start here: how does the tool get onto the page?
There are three methods, and they have completely different consequences. This single question eliminates more of the list than everything else combined.
A proxy, or mirror
The tool fetches your site on its own servers and serves you a copy with the commenting layer already on it. You paste a URL and it works. Nobody touches your code, nobody installs anything, and your client clicks one link.
The cost is that a proxy can only reach pages it can reach. A staging site behind HTTP Basic Auth, or anything that requires a login, is usually a hard stop — the proxy arrives at the password prompt, same as any other anonymous visitor. Heavily scripted apps can also behave oddly when served through a rewriter.
A script snippet
You add a line of JavaScript to your site. The commenting layer then runs on the real page, in its real environment, at its real URL.
This is the most capable method. It works behind logins, on staging, and on localhost, because it is running inside the authenticated session rather than trying to get in from outside. The cost is that somebody has to deploy code, which rules it out immediately if you are reviewing a site you do not control — a prospect’s site, a competitor’s, or a client build you have not been given access to.
A browser extension
Each reviewer installs an extension, which injects the commenting layer locally on whatever page they are looking at.
It works anywhere, including behind logins and on sites you do not own, with nothing deployed. The cost lands on your reviewers: every one of them has to install software before they can leave a single comment. For an internal QA team that is a one-off annoyance. For a client who reviews one site a year, it is often where the process quietly dies.
Several tools offer more than one of these. The point is not that one method wins — it is that you should decide which you need before you look at anything else, because it is the constraint that cannot be worked around.
Three more questions worth answering first
- 1Who is actually leaving the feedback? A non-technical client needs a link that opens and works, with no account and no download. An internal QA engineer benefits enormously from automatic console logs, network traces and session replay — which are wasted on a client, and sometimes alarming to them.
- 2Where does the work end up? If your team already lives in Jira or Linear, deep two-way sync matters more than any board the tool ships with. If you do not have a tracker, a built-in board saves you buying a second product. The failure mode to avoid is a tool whose feedback has to be re-typed somewhere else by hand.
- 3How many screen sizes do you have to sign off? Most of the arguments in website review are about what happens between breakpoints. If responsive sign-off is part of what you are paid for, a tool that only reviews at the reviewer’s own window size will not cover it.
The tools, and what each is genuinely best at
BugHerd — the default for agency-to-client review
BugHerd attaches feedback to elements on a live or staging page through an extension or a JavaScript snippet, and captures browser, operating system and screen details with every comment. It has its own Kanban board and a long list of integrations. Clients can leave feedback without an account.
It is the most frequently recommended option for agencies for a reason: the combination of pinned client feedback plus a board plus technical metadata covers the whole loop in one product. The trade-off is the install step.
Pastel — the lightest thing to hand a client
Pastel lets guests comment with no login on live sites as well as images and PDFs, and checks across screen sizes. It is built to push feedback into the tools you already use rather than to be the place work lives. It holds SOC 2 certification, which stops the conversation early if procurement is involved.
Pick it when review spans websites and static files, and you already have somewhere for tasks to go.
Marker.io — the strongest option when developers are the audience
Marker.io is built for bug reporting and formal user acceptance testing. Reporters annotate a high-fidelity screenshot through an embedded widget, and every report arrives with browser, operating system, screen size, console logs and network requests attached. It includes session replay, and two-way sync with Jira, Linear, Trello, GitHub and Asana — meaning a status change in Jira flows back.
Because it runs as a widget on your own page, it is one of the few tools that works properly on password-protected staging. If reproducing bugs is the expensive part of your week, this is the most rigorous choice here.
Markup.io — breadth of file types, minimal friction
Markup.io handles contextual comments across a very wide range of file types — live sites, images, PDFs, video — with unlimited guests and no registration. It is often the easiest thing to put in front of someone who has never used a review tool.
Worth knowing before you commit: its website review works by proxy, so sites behind basic authentication will not load. Test your actual staging URL during the trial rather than a public page.
Userback — bugs, surveys and feature requests together
Userback combines bug reporting with product research. Feedback comes through a widget or extension and captures a screenshot or screen recording plus console logs, network requests and session replay. On top of that it adds NPS and CSAT surveys and a feature voting portal, and there is a free tier.
Pick it if you want to know what users want as well as what is broken, in one place.
Usersnap — for product teams whose problem is triage, not capture
Usersnap gathers visual feedback through widgets and surveys — screenshots, recordings, annotation, voice — alongside technical bug reports, feature requests and in-app surveys. It connects to a very large number of tools and has AI features for summarising and categorising what comes in.
Pick it if you are receiving more feedback than anyone can read, and sorting it is the actual job.
Ruttl — when you want to suggest the fix, not describe it
Ruttl does comments on live sites and static images, plus an inspect mode that makes real CSS changes on the page — sizes, spacing, colours — which you can export as code. It also handles video comments, integrates with the usual project tools, and has a free plan.
Pick it if your designers would rather adjust the thing than write a paragraph explaining the adjustment.
Atarim — if the answer is always WordPress
Atarim is built around WordPress agency workflow, with its roots in WordPress site management rather than generic review, and a URL-based mode for sites outside it. If the majority of what you ship is WordPress and you want review sitting next to the rest of your site management, it fits a shape the others do not.
UX Peeker — ours, and where it does not fit
We mirror the page rather than asking anyone to install anything, so a project starts by pasting a URL and sharing a link. Clients comment without an account. Every comment becomes a task on a board automatically, which exists because re-typing feedback into a tracker is the step where work most reliably goes missing. Paid plans add review at fixed device sizes, and a design overlay that puts the original mockup on top of the live build so you can see precisely where it drifted. There is also timestamped video review in the same workspace, and a free plan.
Where we are the wrong choice, plainly. Because we mirror rather than inject, a staging site behind a login is awkward for us and straightforward for Marker.io, BugHerd or anything else running a snippet on your own page — if that is your situation, go there. We do not capture console logs, network traces or session replay, so for engineering triage Marker.io is more thorough. And if most of your review work is PDFs and static images rather than live pages, Pastel and Markup.io genuinely cover more formats than we do.
The short version
- Reviewing a staging site behind a login: Marker.io, BugHerd, or anything snippet-based. Proxy tools will not reach it.
- Reviewing sites you do not control at all: a proxy tool or an extension. A snippet is impossible.
- Developers are the audience and reproducing bugs is the pain: Marker.io.
- Clients are the audience and you want zero friction: Pastel, Markup.io or UX Peeker.
- You want feedback and a task board without buying two products: BugHerd or UX Peeker.
- You want bugs plus surveys and feature voting: Userback or Usersnap.
- You want to make the CSS change rather than describe it: Ruttl.
- Almost everything you build is WordPress: Atarim.
The test that predicts whether you will still be using it in a month
Do not evaluate these with a demo site and a colleague. Both of you already understand the tool, so every trial looks like a success. Run it on one real project with one real client, and count the steps between a comment arriving and the fix being deployed.
In most teams that chain is: client leaves a note somewhere, someone reads it, someone re-types it into a tracker, someone assigns it, someone later tries to work out which page it referred to. Five steps, four of them manual, and every one is a place something gets dropped. The tool that removes three of those steps beats the tool with twice the features and a nicer marketing site.
Leaving the comment was never the expensive part. Turning it into finished, tracked, deployed work is.
Why there are no prices here
Because they change, and a stale number is worse than no number. More importantly, the roundups that do quote prices frequently disagree with each other and with the vendor — we found the same tool listed at three different prices across three 2026 comparison posts while researching this one. Check the vendor’s own pricing page, and treat any third-party figure, including ours, as out of date by default.
Nearly all of these have a free tier or a trial. Use it on something real.
