The platform

Built for the modern content team.

Three pillars that turn content updates from a coordination nightmare into a calm, governed, reviewable workflow.

Visual diff

See exactly what's changing — across every content type.

ContentMerge renders intelligent, type-aware diffs for short text, long text, rich text, JSON, references, and assets. Reviewers always see the change in context, never as raw payload.

  • Word-level highlights for prose
  • Side-by-side previews for images
  • Tree-aware diff for JSON & references

Merge requests

A review loop your team will actually use.

Open a merge request from any branch, request reviews, leave comments at the field level, and resolve conversations the way you do on pull requests. No new vocabulary to learn.

  • Threaded comments per field
  • Required reviewers and approvals
  • Slack & email notifications

Heading copy looks great — can we shorten the body to fit the mobile hero?

Pushed an edit. New version is ~30% shorter, keeps the “early access” CTA.

Approved. Ready to merge.

Protection & roles

Decide who can merge into what.

Mark spaces and environments as protected so production can’t be touched without the right role. Built-in READ, PARTIAL_WRITE, WRITE, and ADMIN roles — or define your own permission set for who can compare, open a request, approve, and merge.

  • Per-space and per-environment protection
  • Built-in and custom roles
  • Approvals required before merge

How it works

From draft to production in four moves.

  1. 1

    Connect

    Sign in with your Contentful space and pick a source and target environment.

  2. 2

    Compare

    See a side-by-side diff of every entry, model, and asset that differs between environments.

  3. 3

    Review

    Open a merge request. Reviewers get a real diff, not a screenshot, and approve when ready.

  4. 4

    Merge

    Merge selected entries into the protected target — immediately or after approval.
