Built for how you actually build

You shipped it fast.
Now let your clients edit it.

Mergeline adds a content editing layer to any AI-built site — forms, AI chat, and preview branches — without requiring you to refactor your codebase or adopt a rigid CMS schema.

The friction you know

Every AI-built site hits
the same four walls.

Clients Slack you for every text change

You built a great site. Now you're the content team. Every headline tweak, every product update — it flows through you.

Traditional CMSs want structured content

Contentful and Sanity assume you defined a content schema up front. You didn't. You shipped. Mergeline works with whatever structure you built.

You don't want to refactor the whole thing

Restructuring a weekend build to fit a headless CMS isn't the plan. Mergeline scans your repo and works with your existing structure — not against it.

Clients break things when given too much access

A single config file in your repo defines exactly what clients can see and touch. Everything else is locked.

How Mergeline helps

Built for the way
vibe coders actually ship.

Mergeline meets your site where it is — scans what you've built, generates an editing layer on top, and gives clients a place to work that isn't your inbox.

Compatibility Scanner

Point Mergeline at your repo. We scan the structure — framework, content organization, hardcoded data — and tell you exactly what works, what needs a small adjustment, and what won't fit. No surprises.

Auto-generated Forms

Whatever content structure you have — conventional or fully vibe-coded — Mergeline generates editing forms for it. Clients browse, edit, and upload images without touching code.

AI Chat for Copy Edits

Clients say "update the hero headline to X." The AI reads your template, finds the marked region, and makes the change. You defined the editable zones. The client just talks.

Git-backed Branches

Every client edit creates a branch with a live preview URL. Nothing touches main without your say. Publish directly or require your approval — per site, your call.

Plain-language Diffs

Clients see "Changed headline from 'Welcome' to 'Get Started'." Not a raw diff. No technical explanation required. No support call.

Portable by Default

All assets commit directly to your repo. No proprietary CDN, no platform lock-in. If a client leaves, they take everything with them — their content is always theirs.

Ship the site. Hand off the editing.
Keep the control.

Starts at $9/month for one site. No CMS refactor, no vendor lock-in, no more content requests in your DMs.
