Startup program

Também em portuguêsTambién en español

Who qualifies?

A startup founded less than 2 years ago, building its own product that runs code, for example:

• an online judge, a practice site or a coding course;
• a hiring or assessment tool that judges candidates' code;
• an AI agent or assistant that runs the code it writes;
• a docs site or developer tool with runnable examples.

Teachers, open-source projects and nonprofits can get Free Pro for a link instead. Larger companies can start on the Free plan or a paid one.

What do you get?

First, the Pro plan, free, for 6 months:

• 1,000,000 runs a month (Free has 100,000).
• 600 submissions a minute, 10 runs at once and 120 waiting at a time for the account.
• Everything else in Pro, as listed on the pricing page.

Then 50% off Pro or Business for 6 months, with a promotion code we email you to use at checkout. Business adds 4,000,000 runs a month, 20 runs at once and the option to hide the widget's "Runs on OnlineCompiler.io" line.

The free months are set on your existing account and end on their date; no card is needed and nothing renews on its own. We email you 14 days before they end. When the plan returns to Free, judged submissions older than Free's 90 days are deleted.

What do we ask?

• Your logo on our site. We may show your name and logo on onlinecompiler.io as a startup that builds on us. Beside it we say that startups in the program get our plans free or at a discount.
• A link to us. One visible link to onlinecompiler.io from your site or product: the footer, the docs or the about page. Keep it up while the free and half-price months run.

Copy one of these:

<a href="https://onlinecompiler.io/?utm_source=startups" rel="sponsored">Code runs on OnlineCompiler.io</a>

[Code runs on OnlineCompiler.io](https://onlinecompiler.io/?utm_source=startups)

Keep rel="sponsored" in the HTML link: Google asks for it on links given in exchange for something, and it changes nothing for your visitors.

How does it work?

1. Add the link.
2. Send the form below: your startup's name and site, when it was founded, what it builds and how it runs code, the page with the link, and the email of your OnlineCompiler.io account. No account yet? Sign up free first.
3. Within 5 working days we look at your application, then set Pro on your account and email you, or tell you why not. We may ask you for your logo file.
4. 14 days before the free months end we email you a reminder and the promotion code for the half-price months. Choose Pro or Business under Plan & billing with the code, or do nothing and the account returns to Free.

The rules

• We read every application and may say no, for example to a company older than 2 years, a product that doesn't run code, or a site made just for the link.
• One startup, one account, once.
• If the link comes down, the free plan may end early. We email you at least 14 days before.
• If you write about us, say that you got Pro free.
• We may change or end the program. Plans and codes already given keep their terms.

Apply

We reply to the email you give here. Questions first? Write to hello@onlinecompiler.io.

Frequently asked questions

Do I need an account first?

Yes. The plan is set on an OnlineCompiler.io account, so sign up free first and give its email in the form.

Do I need a card?

Not for the 6 free months: no card is taken and nothing renews on its own. The half-price months are a paid plan, so you choose it under Plan & billing and pay by card.

What happens after the 6 free months?

The plan returns to Free on its date, unless you choose Pro or Business with the promotion code we email you, which takes 50% off for 6 months. After those months the plan renews at its full price until you change or cancel it. When the plan returns to Free, judged submissions older than Free's 90 days are deleted.

Can we have Platform instead?

The program covers Pro and Business. If you need Platform's uptime promise or booked busy days, ask for its 30-day free pilot instead.

How is this different from Free Pro for a link?

Free Pro for a link is for teachers, open-source projects and nonprofits. This program is for young companies building a product, and asks for your logo as well as a link.
