Build internal tools directly in your app's codebase
Interval supercharges your backend code with UIs, auth, audit logs, and more, leaving more time to focus on writing the code that matters.

Actions
Skip the boilerplate, just write your backend
Interval is a batteries-included approach to building internal tools within your codebase. Just write business logic to power your tools in your backend, Interval handles the rest.
User interfaces
Nobody wants to spend time building UIs for internal tools. With Interval, just write business logic and sprinkle in calls to I/O methods when you need to collect input or display output.
Explore I/O methods Because you're collecting input and displaying output right from your Node app, there's no need for REST/GraphQL APIs to connect a frontend and backend.
const data = await db.charges.find({ userId: user.id });
const charges = await io.select.table('Select charges', {
data,
});

Authentication
By the time your Interval code is called, users have already been fully authenticated through email, Google, or SSO.

Use the logging API to display progress to users running your Interval apps and to store logs for audits + reference.

ctx.log('Skipped already refunded charge:', charge.id);

Notifications
Dispatch notifications directly from your Interval actions. Your teammates can receive notifications however they want: through your group messaging app or email.
Notifications docs if (refundAmount > 10) {
await ctx.notify({
title: 'Refund over threshold',
message: `A charge of ${refundAmount} has been refunded.`,
});
}

Scheduled actionsComing soon
Automatically run actions on an hourly, daily, weekly, or monthly schedule. Receive notifications when actions complete, and use I/O methods to prompt for user intervention whenever unexpected conditions occur.

Other tools force you to learn how to work in their custom environments and runtimes. Interval provides powerful primitives, then gets out of your way as much as possible.
Made for Node + TypeScript
We built Interval from the ground up specifically for Node + TypeScript. Interval's I/O methods do the heavy lifting of parsing, sanitizing, and type checking all user input. With Interval, your code is safer by default.
const = await io.search('Find a user', {
placeholder: 'Search by name, email, or ID',
onSearch: async query => db.findUsers(query),
});
const user
const user: {
id: string;
email: string;
firstName: string;
lastName: string;
imageUrl: string | null;
}
Build in your codebase
Love your ORM? Interval is just a regular Node module. When you add Interval to your existing app, you can use the same shared functions, environment variables, and 3rd party libraries as the rest of your app.
Build in code
Interval is designed for 100% compatibility with your existing codebase. Actions are just functions that you run in your Node.js backend, and our library of I/O methods are just async functions.
Secure by default
Interval apps are deployed on your infra, not ours. And because Interval is only collecting input and displaying output, we receive only the data you choose to send to us - and that data is never stored or logged on our servers.
