Who it is for
Three kinds of builder.
Anyone who can run a web service over HTTPS can build a plugin. What differs is who you build it for.
Agencies building for clients
Build a plugin for your own team or your agency’s client workspaces. Private plugins are not reviewed and not listed.
Products that connect
Connect the product you already have to the apps your customers use, and let them install the connection themselves.
What you can build
One Scale API. 16 apps.
Each app publishes what a plugin may read, change and listen for. Your plugin asks for the areas it needs, and the workspace owner approves them. Across the 16 apps there are 253 actions and 106 events.
A few areas from each app are shown. The full list, with every action, event and permission, is in the developer docs.
What a plugin can do
A normal web service, inside the apps.
Scale never runs your code. A plugin talks to Scale over HTTPS, so you can write it in any language.
Read and change data
Call the Scale API for the workspace that installed you. Reading and editing drafts happen at once.
Ask to act
Actions that reach customers wait for a person to approve them inside the app.
Receive signed events
Scale sends your plugin a signed event when something happens in the workspace.
Show your own screen
Your own screen appears inside the app your plugin works with.
How it works
Four steps to an installed plugin.
Steps one and two are all a private plugin needs. Steps three and four are for plugins listed in the Scale Plugin Store.
Register your plugin
Agree to the developer terms, then register the plugin in the developer console.
Build it
Use the Scale SDK and the starter plugin, on your own servers.
Submit for review
Write the listing and send the plugin to the Scale team for review.
Get installed and paid
Owners read what your plugin asks for and approve it. Paid sales go to your own Stripe account.
The business terms
The terms, stated plainly.
Four statements you can read before you write a line of code.
Free to list
Free plugins are free to list in the Scale Plugin Store.
30% platform fee
On a paid plugin, Scale takes a 30% platform fee from each sale.
You are the seller of record
The buyer buys from you. Each sale is paid through your own Stripe account.
You host your plugin
Your plugin runs on your own servers. Scale never runs your code.
Private and public
You choose who it is for.
Private plugins are for your own team, your agency’s clients, or people you invite. They are not reviewed and they do not appear in the store. Public plugins are reviewed by the Scale team before they are listed.
What review checks
- It does what the listing says.
- It asks only for the permissions it uses.
- Its addresses are yours and use https.
- The listing is complete and honest.
- The support and privacy links work.
You are told either that your plugin is listed, or what to change.
The tools
What you build with.
Start from a working example, keep the docs open beside it, and manage everything from one console.
Scale SDK
The toolkit for building a plugin. It handles the parts every plugin needs, so you do not write them by hand.
Starter plugin
A working plugin built with the Scale SDK. Run it, then change it into yours.
Developer docs
The quick start, permissions, the Scale API, and each app’s actions and events. Open to read now.
Developer console
Register your plugin, set its permissions, write the listing and send it for review.
Signed events
Your plugin is told when things happen in a workspace, with a signature you can check.
Your screen in the app
Show your own screen inside the app your plugin works with.
Build with a coding agent
Hand the docs to your agent.
The developer docs include copy-ready prompts for coding agents, and the starter plugin includes an agent instructions file. Give both to the agent you already use and let it do the first pass.
Prompt · illustrationCopy
Read the agent instructions file in the starter plugin, then set the starter up so I can run it in my own workspace.
Prompt · illustrationCopy
Change the starter plugin so it asks only for the permissions my idea needs, and tell me what the workspace owner will read.
Where things stand
In preview. Open to developers.

Developer questions
Can I sign up as a developer today?
Yes. Sign in to Scale, open Build on Scale and accept the developer terms. The developer docs are open to read before you sign up.
What does it cost to list a plugin?
Free plugins are free to list. On a paid plugin, Scale takes a 30% platform fee from each sale.
How do I get paid?
Each sale of a paid plugin is paid through your own Stripe account. You are the seller of record.
Where does my plugin run?
On your own servers. Scale never runs your code. Your plugin talks to Scale through the Scale API, signed events and the in-app frame.
What language can I write a plugin in?
Any language that can serve HTTPS. The Scale SDK is a TypeScript package that handles the fiddly parts.
Do I need review to use a plugin myself?
No. A plugin for your own team, your agency's clients or people you invite is private. It is not reviewed and it is not listed.
How long does review take?
There is no fixed time. Every public plugin is reviewed by the Scale team, and you are told either that it is listed or what to change.
