AnnotationBase

AnnotationBase is a browser-based workspace for marking up websites and managing feedback in context. It fits freelancers, agencies, and delivery teams that need clients to review pages without creating accounts. The free tier works for small workloads; growing teams will need Pro for unlimited projects and collaborators.

Overview

Reviewers click an element on a live page, staging site, or browser-accessible localhost site and attach a comment there. They can add explanatory context, screenshots, and teammate tags, while replies, changes, and resolution status remain in one element-specific thread. That structure is more actionable than a detached list of page-wide notes when a discussion depends on an exact button, image, or section.

Shared-link guest access lets clients and other stakeholders comment without an account or download. There is no browser extension, code installation, or onboarding call, so a project can move into review with little setup. AnnotationBase is focused on webpage comments rather than general document annotation. It supports sites built with Elementor, Framer, Shopify, Squarespace, Webflow, Wix, WordPress, and GoDaddy.

Key features

Threaded visual feedback

Element pins preserve the location under discussion, and threaded replies keep clarification and resolution together. This suits design and development handoffs where an issue must remain traceable from report to fix. Collaborative review is built in, but the annotation mode is comments and the document type is webpages, so it is not a broad markup system for arbitrary files.

Guest review and AI export

External reviewers can participate through a shared link, removing account friction for client approvals or occasional stakeholder input. Open feedback can be exported as a structured prompt for an AI editor, giving teams a way to turn unresolved notes into editing instructions. Users can also export all comments and project data at any time.

Privacy and operational assurances

AnnotationBase says it does not sell personal data or share it with third parties for marketing. The operator identifies itself as a controller under UK and EU GDPR; passwords are encrypted, Stripe handles PCI DSS-compliant payments, and hosting is described as UK or EU based. API access is coming soon, with planned Linear, Notion, Jira, and custom-system connections, so teams needing current integrations must wait.

Pricing

Lite is enough for an individual or small client roster, but the five-project and five-collaborator ceilings will constrain an agency running several concurrent sites. Monthly Pro offers flexibility at £9.99 per month; Yearly Pro lowers the effective monthly cost for teams committed to continuous use. Both paid plans remove the two key capacity limits. Approved refund requests are handled by email, with a response target of five business days.

Platforms

AnnotationBase is a web service. It can review live, staging, and localhost websites opened in a browser, with no extension or installed code required.

Who it's for

Project managers, freelancers, designers, developers, agencies, and their clients will benefit when feedback must point to a precise webpage element. Guest links are especially useful for external approvals. Choose another category of tool if your workflow centers on non-web documents, or if immediate API connections to project systems are essential.

Pros and cons

• Pros: comments stay anchored to page elements; replies and resolution remain in context; guests need no account or download; works on staging and localhost sites; exports AI-ready instructions and project data; UK/EU hosting and stated GDPR responsibilities.
• Cons: the free plan allows only five active projects and five collaborators; webpage comments are the sole annotation format; API integrations are not yet available.
