Markup.io and Marker.io get lumped together because of the name, and almost nothing else. One is a visual review tool for files. The other is a bug reporter for live websites. If you've been comparing them on price alone, you're comparing the wrong thing. Here's what each one is actually built for, where they differ feature by feature, and how to pick.
What Markup.io is built for
Markup.io is made by Ceros, a company that builds interactive content tools, not dev tools. That history shows in the product: it's a visual review tool for more than 30 file types — images, PDFs, video, and web pages via a shared link or browser extension. Reviewers drop pins, draw, highlight, and leave threaded comments with priority labels, and guest access needs no sign-up, which is a real strength for a quick external review.
What Markup.io isn't built around is a live, interactive page. A screenshot or a linked page gets a pin and a comment, not the browser, device, and viewport context a bug report usually needs. It's a proofing tool first — built for design and creative teams reviewing a mockup, a deck, or a video cut, not for a team fixing issues on a site that's already in staging or live.
What Marker.io is built for
Marker.io is the opposite case: a feedback and bug-reporting tool for dev teams working on a live website. It installs as a script tag, with a browser extension or in-page widget for reporters. When someone flags an issue, Marker.io captures the screenshot along with console logs, network requests, and browser metadata — context a developer can actually act on without asking "which browser were you on?"
The tradeoff is the setup. A reporter needs to install the extension or be comfortable with an in-page widget, which is a bigger ask than opening a shared link. For an internal QA team or a client who's technical enough to not mind an extra step, that's a fair trade for the extra detail. For a non-technical client who just wants to point at something on the page, it's friction they may not get past.
Markup.io vs Marker.io: feature by feature
| Markup.io | Marker.io | |
|---|---|---|
| Starting price | Pro from $79/month (monthly billing, 50 MarkUps) | Starter at $59/month (3 users, 10 projects), $39/month billed yearly |
| What it reviews | Screenshots, PDFs, images, video, and pages via link or extension | A live website, through an installed script tag |
| Client-facing UX | Shared link, no sign-up — but it's a copy of the page, not the page itself | Browser extension or in-page widget — reports directly on the live page, but needs an install or an extra step |
| Technical context captured | Pin location and a comment — no browser or device metadata | Screenshot plus console logs, network requests, and browser metadata |
| Integrations | Advertised across all plans, but deeper API/SDK capacity is reserved for Business and Enterprise | Trello, Asana, ClickUp, GitHub, GitLab, Linear, and Notion on Starter; Jira added on Team and above |
| Best for | Design and creative teams proofing files before anything ships | Dev teams reporting and fixing bugs on a live product |
The pricing isn't really a fair fight once you look past the sticker: Markup.io's per-month cost is driven by how many "MarkUps" (its unit for a reviewed file) you need, while Marker.io's is driven by team seats and active projects. They're charging for different things because they're selling different things.
So which one should you use?
Start with what you're actually reviewing. If it's a static file — a PDF, a design comp, a video cut, a deck — before anything is built, Markup.io does that job well, and its no-sign-up guest link is genuinely convenient for outside reviewers.
If you're past that point and working on a live or staging website, Marker.io is the closer fit of the two. Its script tag and console-log capture give developers real debugging context that a static markup tool can't. The cost is asking your reporters — client, QA tester, or teammate — to install an extension or use an in-page widget instead of just clicking a link.
Neither tool is wrong. They're just answering different questions: "what does this file look like to a reviewer?" versus "what broke on this live page, and why?"
Where tapko.app fits
Neither Markup.io nor Marker.io is built for the specific case a lot of small agencies run into: a non-technical client who needs to react to a live website, with zero account creation and zero extension install, and who expects that comment to land somewhere your team already works.
tapko.app is built for that case specifically. Clients open a shared link and click anywhere on the live site — no sign-up, no extension — and the tool automatically captures the screenshot, URL, device, browser, and viewport behind the comment. Reports push into ClickUp, Slack, Jira, Asana, Notion, or Trello, so feedback doesn't sit in a separate inbox waiting to be copied into your actual workflow.
Pricing: First project free forever. Pro plan with unlimited projects at $49/month.
Best for: Agencies whose clients won't create an account or install anything.
Integrations: ClickUp, Slack, Jira, Asana, Notion, Trello.
If your review cycle is files before launch, stick with Markup.io. If your team needs console-level debugging on a live product, Marker.io earns its setup cost. If the person leaving feedback is a client who just wants to point at what's wrong and move on, that's the gap tapko.app was built to fill.
Frequently Asked Questions
What is the main difference between Markup.io and Marker.io?
Markup.io is built for reviewing static assets — screenshots, PDFs, images, and video — with guest access and no sign-up required. Marker.io is built for reporting bugs on a live website, using a script tag and browser extension that capture console logs and technical context alongside the screenshot.
Which is better for client feedback on a live website?
Marker.io is the closer fit of the two, since it is built around a live page rather than a static file. Its browser extension or in-page widget is still a bigger ask for a non-technical client than a tool built around a single click, no install.
Do Markup.io and Marker.io integrate with project management tools?
Marker.io connects to Trello, Asana, ClickUp, GitHub, GitLab, Linear, and Notion on its Starter plan, with Jira added on higher tiers. Markup.io advertises integrations across its plans but has moved deeper API and SDK capacity to its paid Business and Enterprise tiers.
Is there a simpler alternative to both for agencies?
tapko.app is built specifically for agencies with non-technical clients. Clients click directly on the live site with no account and no install, and reports push into ClickUp, Slack, Jira, Asana, Notion, or Trello. Pro includes unlimited projects at $49/month, and the first project is free forever.
