Bolt.new has a free plan. Free tier, 300K tokens a day and 1M a month
The whole thing runs in the browser, which is why you can go from a sentence to a running app without installing anything.
Tools that do comparable work, best fit first, drawn from the catalogue rather than hand-picked. Every one is listed whether or not there is money in it for us.
Best general option for explaining unfamiliar code, debugging a single file, or analysing a spreadsheet with real Python behind it.
View ChatGPT →Reads long files and whole error traces without losing the thread, which makes it good at explaining unfamiliar code and debugging in a chat window.
View Claude →Reviews pull requests line by line and leaves comments in the diff, with the reasoning attached rather than a score.
View CodeRabbit →The editor most professional developers have converged on. Understands a whole codebase, not just the open file.
View Cursor →The default, and the one already wired into the editor and the pull request your team uses. A free tier now covers light use.
View GitHub Copilot →Upload a spreadsheet and it writes and runs real code against it, showing the working rather than describing it.
View Julius AI →Where Bolt.new sits in the wider category pages.
Strong fit — Programming, debugging, data analysis, spreadsheets, math, engineering, technical research.
Yes โ Free tier, 300K tokens a day and 1M a month. The cheapest paid tier is Pro, at $25/mo month to month or $18/mo billed yearly.
Describe an app and it builds and runs it in the browser, with the code editable and deployable from there. It is listed under Coding, Data & Technical Work.
Credits burn quickly on iteration, and a generated app is a prototype until someone reads it. Pro is sold in token tiers from 10M a month up, so its price is the entry rate rather than the bill.
6 tools do comparable work: ChatGPT, Claude, CodeRabbit, Cursor, GitHub Copilot, Julius AI. 6 of them have a free plan.
