Token limits still bite. Refraction caps inputs at 8000 tokens—sounds generous until you're staring down a sprawling legacy class. The team bumped it up from 3000, so they're listening.

Paste code into Refraction. It spits back refactored versions, unit tests, or documentation. Pick from 56 languages. Not a typo. You get mainstream JavaScript and Python alongside oddities like CameLIGO and PascaLIGO. Backend engineers working in Scala or Elixir? Same treatment as frontend developers stuck in React components.

No ceremony required. Select your language. Choose what you need. Wait a few seconds. Over 13,000 developers have generated north of 65 million lines through it—real usage numbers.

Got a messy API handler that's grown arms and legs over three years? Refraction suggests cleaner patterns. Or at least generates the test coverage you've been avoiding. It won't solve architectural problems. Won't tell you your whole approach is wrong. But it handles tedious stuff.

There's a free plan. Main features aren't locked behind a paywall. You get access to refactoring, documentation, and test generation without pulling out a credit card. For something that's eaten this many languages (and keeps bumping its token ceiling), that's not the worst deal.

Just don't expect it to rewrite your entire codebase in one shot.

Frequently asked

7 questions
How many programming languages does Refraction support?
Refraction supports 56 programming languages, from mainstream ones like JavaScript, Python, and Java to niche languages like CameLIGO, PascaLIGO, and Solidity. Whether you're writing frontend React code or backend Elixir services, it'll handle your language.
Is Refraction free to use?
Yes, Refraction has a free plan that gives you access to the main features like code refactoring, documentation generation, and unit test creation. You don't need a credit card to start using it.
What is Refraction's token limit?
The current token limit is 8000 tokens per input, which they raised from 3000. That's decent for most functions and classes, but if you're trying to paste an entire sprawling legacy file, you'll still hit the ceiling.
Can Refraction generate unit tests automatically?
Yeah, it can generate unit tests for your code. Just paste your code block, select your language, and tell it you want tests. It's pretty handy for covering those functions you've been putting off testing.
What can I use Refraction for?
You can use it to refactor messy code, generate documentation you've been avoiding, or create unit tests automatically. It's basically for handling the tedious stuff that eats up your time but doesn't require deep architectural thinking.
Does Refraction work with TypeScript and React?
Absolutely. TypeScript and JavaScript (including React) are among the 56 supported languages. It'll refactor your components, generate tests, or write documentation just like it would for any other language.
How accurate is Refraction's code generation?
It's pretty solid for standard refactoring patterns and test generation, but it won't solve architectural problems or tell you your whole approach is flawed. Think of it as a helpful assistant for routine tasks, not a replacement for actually understanding your code.
