You built something. Now what?

Three people who had a working app and nowhere useful to put it.

The AI builder
"I built it in Claude. It works. But I can’t share it with anyone."
You prompted your way to something genuinely useful. A tracker, a calculator, a form that does exactly what you need. It lives in a chat window. You cannot send someone a link. You cannot give your team access. It just sits there.
And the moment you close the tab it is gone.
Install merebase. Deploy it. Hand them the link.
The developer or freelancer
"I need to ship a custom tool for a client and I needed it last week."
Every client site needs something slightly different. A staff tool, a job tracker, a custom form. Building the auth and storage from scratch every time is the expensive part. The feature itself is small. The plumbing around it is not.
And you end up billing for infrastructure instead of the feature.
merebase handles the plumbing. You ship the feature.
The small business owner
"I just need an app that does one thing. Why is that so hard?"
Every platform does fifty things. You need two or three. You cannot leave because those features are load bearing and the platform knows it. You have been putting off finding an alternative for a year because the alternative looks like a project.
And next month the price goes up again.
One WordPress site. One plugin. One focused app. Done.
From a recent build

"We were tracking sign installations across three suburbs in a Google Sheet. Three people updating it, no mobile access, constant mistakes. merebase gave us a tracker with photo upload and job sign-off. Four days."

Signage company, Brisbane  ·  Replaced a Google Sheet  ·  Live in four days

The plumbing should not cost more than the feature.

Auth. Storage. Access control. Version history. These are not interesting problems. Nobody wants to solve them. They are the reason custom tools do not get built, because the infrastructure around a small app costs more time and money than the app itself.

merebase solves them once. Install the plugin and every app you build or deploy has everything it needs already running. Your app is a single HTML file. The rest is already done.

That is not a workaround. It is the architecture.

How it works

From plugin to live app in three steps.

If WordPress runs there, merebase runs there. Your site is already the platform.

01
Install the free plugin
One click from the WordPress directory. Auth, KV storage, entity storage, access control, and version history are live immediately. No configuration required. The plugin handles everything your app needs on the server side so your app files stay simple.
Free · One click · No card required
02
Deploy your app
Build your app as a single HTML file using any AI tool. Claude, Cursor, ChatGPT, whatever you use. Drop it into merebase through the plugin. Your app is live at a clean URL on your own site in under a minute. No server to configure. No deployment pipeline.
Single HTML file · One command · Clean URL
03
Control who sees it
Public, private, or shared with specific people. Set access by domain, by email with a magic link, or by IP address. No passwords for your users to manage or forget. One click in an email and they are in. Change it any time from the plugin admin.
Magic link · Domain · IP · Your rules

Open source

Your site. Your data. Your code.

The merebase plugin is free and open source under GPL v2. Your data stays on your own WordPress hosting. We do not touch it, host it, or hold it. Nothing about your setup changes if you stop using merebase. What you built is yours. Full stop.

Apps are static HTML and JavaScript files. No PHP in the app files. No proprietary runtime. No magic that breaks unexpectedly. The plugin handles the server-side logic once so your apps stay simple, portable, and fast.

Apps start as a single HTML file and can grow as complex as the job requires. Images, additional scripts, external assets, multi-entity data structures with conditional logic. The file format does not define the ceiling. The plugin handles what runs behind it so you can put all your complexity into the thing that actually matters.

Still not sure?

Coming from Notion, Retool, HubSpot, or something else?

If you’re on a platform that almost fits but not quite — or paying for fifty features to use three — there’s a longer answer to whether merebase is the right call.
