Free Tier

Our free offerings are designed you so you can quickly use Corsfix with your website.

Development

You can instantly use our proxy in your local development environment (localhost).

• No registration required
• Use in local domains (localhost, 127.0.0.1, 192.168.x.x, 0.0.0.0, etc)
• 60 requests per minute

Production (Free)

Use Corsfix on your live website for free, with no time limit. The free tier requires the Corsfix SDK, available from CDN or NPM.

• No registration required
• 1 concurrent user
• 10 MB monthly data transfer per domain (goes up to 100 MB when you add your application)
• 60 requests per minute (per IP)
• All file sizes and types

Install the SDK and fetch as usual:

<script src="https://unpkg.com/corsfix"></script>
<script>
  corsfix
    .fetch("https://api.example.com/data")
    .then((response) => response.json())
    .then((data) => console.log(data));
</script>

Or with npm:

import corsfix from "corsfix";

corsfix.fetch("https://api.example.com/data");

Data transfer is counted per origin domain and resets at the start of each month (UTC). Registering a domain does not reset its usage, it only raises the allowance to 100 MB. A registered free account can have one application with one origin domain.

When your website reaches a limit, requests fail with a free_tier_transfer_limit or free_tier_concurrency_limit error and the SDK shows a small notice in the corner of the page. Register your domain for a higher allowance, or upgrade to a paid plan to remove the limits.

Production (Trial)

Try every Corsfix feature on your live website for 7 days, free of charge.

• All features included, such as cached response and secrets variables
• 1 GB data transfer and 3 web apps included
• 60 requests per minute

Activate the trial from the billing page in the dashboard. It can be activated once per account, and when it ends your website goes back to the free tier until you upgrade.
