How it works

Four steps. You stay in charge.

Versionly watches the APIs your selected projects use. When those APIs change, you get a pull request to review — not an automatic merge.

01 · Connect

Link the GitHub repos you want watched.

You choose the projects. Nothing else is scanned.

02 · Detect

We watch the third-party APIs those projects call.

When a vendor changes their API, you hear about it here first.

Impact map

Two files. One line each.

src/billing.ts

Your code now
12export async function charge(id: string) {
13  return stripe.paymentIntents.confirm(id, {
14    api_key: process.env.STRIPE_KEY,
15  })
16}

src/billing.ts

Versionly suggests
12export async function charge(id: string) {
13  return stripe.paymentIntents.confirm(id, {
14    stripeAccount: process.env.STRIPE_KEY,
15  })
16}

04 · Review

A pull request is opened. Your team merges it.

Suggested code arrives as a PR. You remain the editor-in-chief.
