Markup.io vs Marker.io: You're Probably Looking for One of Them [2026]

TL;DR#

Despite the near-identical names, these are tools for two different jobs. Markup.io is a design review tool: clients comment on a proxied version of your site or on uploaded assets, unlimited users, flat $79/mo. Marker.io is a bug reporting tool: logged-in team members file screenshot tickets with console logs and network requests attached, straight into Jira or Linear. Decide which job you are hiring for and the choice makes itself. If the job is client review, note that Markup.io has real product problems in 2026 (paid-only evaluation, a screenshot placement bug in our testing, slow development), and a no-signup tool like Simple Commenter is worth testing first (alternatives below).

Two names one letter apart, two different categories#

This comparison exists because of the names. Markup.io and Marker.io get typed into the same searches, recommended in the same threads, and confused in the same Slack messages. But put them side by side and they barely overlap: one is built for design agencies collecting client feedback, the other for product teams collecting developer-ready bug reports.

So this post does two jobs. First, it sorts out which tool does what, so you know which name you were actually looking for. Second, it reviews both honestly, because we paid for and tested each while writing our guide to the 13 best website feedback tools. Full disclosure: we also build Simple Commenter, a tool in the same category. The findings below stand on their own either way.

Markup.io review#

Built for: Agencies · Freelancers

Best for: Design agencies reviewing client work on WordPress or Squarespace sites. Hard to recommend for Basic Auth sites or teams that want to test before paying.

Markup.io is the design review side of this pair. Reviewers leave visual comments on websites and images, count on unlimited users, and never think about tickets or trackers.

There is no free tier and no card-free trial, so we paid to test it, and this review is based on that hands-on time. Installation has two paths. The proxy: paste a URL and Markup serves your site through a Markup-hosted address that reviewers comment on. Convenient, but sites behind Basic Auth will not load through it. The Chrome extension: works on the live page and is the better experience, though it has a visible bug where hovering draws a border around every div under the cursor.

Two findings from our testing matter more than the feature list. First, the automatic screenshot on comments was captured from a totally different spot than where the comment was placed, which is not a small bug for a tool whose main capture format is a screenshot. Second, the product is moving slowly: across all of 2025 the team shipped roughly six features, and the integration list remains short (Zapier, Slack, Microsoft Teams, Loom, with ClickUp "coming soon" and no Jira, Trello, or Asana story beyond Zapier).

The genuine strength is pricing shape. One Pro plan at $79/mo with unlimited users, unlimited markups, and 500 GB storage. No per-seat math at all, which for a big distributed review pool is real money saved. For a solo designer or a small studio, though, $79/mo with no entry tier is steep against tools starting at $29 to $39, and the full picture is why we wrote up Markup.io alternatives separately.

Key features:

• Proxy-based review (no script needed) plus a Chrome extension for live pages
• Automatic screenshot on every comment
• Unlimited users on one flat plan
• Loom integration for video inside comments
• Folders and shareable links

Pricing:

• Pro $79/mo (unlimited users, 1 workspace, unlimited markups, 500 GB storage)
• No free tier; credit card required to create an account

Pros:

• Flat pricing with unlimited users
• No-script proxy install for quick client review setups
• Easy for non-technical clients once inside

Cons:

• Credit card required just to evaluate
• Screenshots captured from the wrong spot in our testing
• Proxy fails on Basic Auth sites
• Short integration list; nothing native for Jira, Trello, or Asana
• Roughly six features shipped in all of 2025
• No data export

Reviews:

Public reviews skew positive on ease of use and how quickly clients pick it up, which matches its design-review DNA. The recurring complaints are pricing (one steep tier for every use case) and specific unfixed gaps: no export, slow proxy page loads, and a Zapier integration without historical sync. A caution on freshness: many glowing reviews date to early 2023 and reference a free tier that no longer exists. Recent reviews spend more time on what is missing.

Marker.io review#

Built for: SaaS teams · In-house product teams · QA teams

Best for: Product teams and dev-supported organizations that need bug reports with debugging data, delivered into their tracker.

Marker.io is the bug reporting side of this pair, and everything about it follows from that. Onboarding asks for your integrations first because the product is a delivery pipe: feedback goes in on the website, tickets come out in Jira, Linear, Asana, Trello, ClickUp, or Monday, with two-way sync so status changes flow back.

There are no pins on the page and no comment threads anchored to elements. A reviewer opens the widget, captures a screenshot, fills out a ticket form, and submits. What elevates this above a screenshot tool is the payload: every report automatically includes console logs, network requests, browser environment, and reproduction steps. A marketer reports "the form is broken" and the developer receives the failed API call and the JavaScript error without asking a single follow-up question. That is the pitch, and nothing else in the category does it better, as we found when comparing it against BugHerd in Marker.io vs BugHerd.

The requirements that follow from the model: everyone leaving feedback logs in, each client workspace bills as a separate team, reviewers cannot see existing tickets (so duplicates happen), and assets like images or PDFs are out of scope entirely. Installation is broad (script, Chrome extension, npm, and CMS plugins for WordPress, Drupal, Webflow, and Shopify), and the security posture is enterprise-grade with SSO SAML, audit logs, and SOC 2 Type 2.

Key features:

• Console logs, network requests, and browser metadata captured on every ticket
• Two-way sync with Jira, Linear, Asana, Trello, ClickUp, Monday
• Script, extension, npm, and CMS plugin installs
• Session replay on Team and above
• SOC 2 Type 2, SSO SAML, audit logs, data masking

Pricing:

• Starter $39/mo (3 seats, 1 active website)
• Team $149/mo (15 seats, 3 websites, session replay, custom branding)
• Business custom (unlimited, SSO SAML)
• Agency $129/mo or $99/mo billed annually (15 members, 50 websites, 50 guests)
• 15-day free trial, no credit card required

Pros:

• Best debugging capture in the category
• Real two-way tracker sync, not one-way pushes
• Card-free trial, unlike Markup.io
• Enterprise compliance features
• Actively developed

Cons:

• Everyone logs in; a poor fit for client review
• No on-page pins or conversations
• Duplicate reports from no on-page ticket visibility
• No asset (image/PDF/video) feedback
• Per-seat and per-workspace pricing compounds for agencies

Reviews:

G2 reviewers praise the captured debugging data and how effectively non-technical staff file actionable bugs; L'Oréal-scale case studies reinforce the centralized-dev-team fit. Critics are consistent too: small teams call it overkill, and the duplicate-report friction comes up repeatedly. It is a strong product being bought by some wrong-fit teams because of its brand gravity, which our Marker.io alternatives page digs into.

Markup.io or Marker.io: which name were you looking for?#

Ask one question: who reads the feedback?

If the answer is a designer or account manager collecting client opinions ("make the logo bigger", "wrong image on mobile"), you were looking for Markup.io's category: design review. Clients need zero technical context and maximum ease.

If the answer is a developer fixing defects, you were looking for Marker.io's category: bug reporting. The value is in the console logs and the Jira sync, and the login friction is acceptable because reviewers are on the payroll.

Cross-shopping them directly only makes sense if you genuinely do both jobs with one tool, and then the honest answer is that neither is great at the other's job: Markup.io captures no technical context at all, and Marker.io is too heavy a flow for client rounds. Tools built around no-signup on-page commenting cover that middle ground better.

3 alternatives worth shortlisting#

Given the real weaknesses in this pair (Markup.io's stalled development and paid-only evaluation, Marker.io's login-gated client experience), here is what we would test alongside them. The full field is in the 13 best website feedback tools guide.

1. Simple Commenter#

Best for: Doing both jobs in this comparison with one widget: client review without signups, and structured feedback your team can route to its tracker.

Simple Commenter covers Markup.io's job with less friction than Markup.io: clients comment directly on the live site (no proxy, no Basic Auth problems, no extension), with no account and no credit card required to evaluate. It covers a useful share of Marker.io's job too: comments carry automatic screenshots and technical context, pipe into Slack, Trello, Asana, ClickUp, Linear, Jira, Monday, GitHub, and webhooks, and a native MCP server lets AI coding agents pull feedback and fix it in code.

The differences from this pair are structural. Feedback is pinned on the page and visible to every reviewer, so duplicates do not pile up. Pricing is flat: $34.99/mo Agency covers 10 users, $149.99/mo Business covers 25 with SSO, and adding clients never raises the bill. And where both tools in this comparison treat WordPress as a script-injection target, Simple Commenter's plugin manages comments, replies, members, and settings inside WP admin. The 14-day trial needs no card, which after paying to test Markup.io we consider a feature worth naming.

2. Pastel#

Best for: The Markup.io job on static design deliverables, from a mature product.

If your review work is genuinely static (marketing pages, images, PDFs), Pastel is the seasoned canvas tool: around since 2016, polished UI, unlimited guest reviewers on every plan. The trade-offs are the iframe model (reviewers comment on a Pastel-hosted snapshot, not your live site), no real-device mobile feedback, a 72-hour commenting window on the free tier, and integrations locked to the $119/mo Team plan. For solo creators reviewing design deliverables it remains a fair pick.

3. BugHerd#

Best for: The Marker.io job when your team wants feedback visible on the page, not just in the tracker.

BugHerd pins comments to live page elements with automatic screenshots and manages them on a kanban board, with two-way Jira, Asana, Linear, ClickUp, and Monday sync on Premium ($150/mo). It captures less debugging data than Marker.io (metadata, not console logs) and named reviewers must log in through its hub, but for mixed teams of designers, PMs, and developers it is the strongest established on-page option. We compare the two directly in Marker.io vs BugHerd.

Final verdict#

Markup.io and Marker.io are a spelling accident, not a rivalry. Markup.io is client design review with flat unlimited-user pricing and, in 2026, visible product neglect. Marker.io is developer bug reporting done better than anyone, at prices and login requirements that assume an internal team. Figure out which job you are hiring for, and if that job is "clients comment on our site without friction," test Simple Commenter before paying for either.
