Every client site.
One dashboard.

The overhead you're absorbing

Client content management
shouldn't be your problem.

Content requests pile up across every client

Ten client sites means ten inboxes. A paragraph change for one client, a new product for another, a pricing update somewhere else. It never stops.

No approval workflow

Clients make changes and they go live before you've seen them. One wrong edit and you're in damage control. A proper approval gate should be table stakes.

Training every client on a different tool

Each CMS platform has its own learning curve. Your clients don't want to learn software — they want to change a paragraph. Mergeline keeps it that simple.

No audit trail when something breaks

Something changed. The site looks wrong. You have no idea who did it, when, or what was there before. Every edit should be a record.

How Mergeline helps

An editing layer built
for agency operations.

Client portals, approval workflows, white-label branding, and audit logs — without the overhead of managing a separate CMS platform for each site.

Multi-client Dashboard

Every site you manage in one place. Monitor client activity, track pending change requests, see what's been edited and what's waiting for your review.

Approval Gate

Per-site and optional. Clients draft changes and preview them on a live URL. You review and publish — or let trusted clients self-publish. Configured in a single file in the repo.

White-label Portals

Each client works in a portal at [slug].mergeline.io under your branding. Clients never see the Mergeline name. Upgrade to a custom domain on the Agency plan.

Audit Logs

Full edit history with 90-day retention. See exactly who changed what, when they changed it, and what it looked like before — across every client site you manage.

AI Reduces Support Load

Clients describe what they want in plain English. The AI reads the marked regions in their template and implements the change. Fewer support requests. More time for work that actually bills.

Pricing That Scales With You

Studio at $19/month covers 3 sites with approval gates. Agency at $39/month covers 10 sites with white-label and custom domains. Overage is metered — no sticker shock.
