Development tools
All 31 development tools in the library, with what each one is best for, what it costs to start, whether there is a free plan and what that plan actually limits. Every figure comes from the vendor’s own page, with the date we checked it.
31 tools in this category, listed alphabetically. Every price, free-plan limit and check date below is the vendor-checked fact already published on that tool’s own page on this site.
What to check before you choose
Most of this category is free to start, and the limits sit in compute rather than seats. Cursor’s free plan includes limited agent and chat requests. Lovable gives 5 build credits a day, up to 30 a month, plus 5 lovable.app domains. Webflow’s free Starter site plan allows 2 static pages, 1 GB of bandwidth and 50 form submissions. Hercules lists 15 AI credits a month with publishing on a hercules.app subdomain. Open-weight models are free downloads, so read the licence on each model card before commercial use.
Compare all 31 development tools
Every cell is copied, not calculated. Entry price is the starting figure that tool’s page publishes under “Paid plans from”; where a tool begins on a free tier that figure is $0, which is what its own page shows, and the Free plan? column says which kind of free access that is. Where a page publishes no starting figure, the cell repeats the cheapest plan it does list, word for word, or says the vendor publishes no self-serve price at all. Hard limit repeats that page’s “On the record” line, which is what the vendor states about the free tier. Price checked is the same date the tool page carries.

How we pick
Every row above copies a figure that is already on that tool’s own page on this site, and each of those pages links the vendor’s own pricing page and the date we read it. Where a vendor publishes no limit, or no price, the row says so rather than filling the gap. The order is alphabetical by tool name, not a ranking. Nothing here is bought: no vendor pays for a row, a position or a mention, and where a link to a vendor is an affiliate link it is marked on the tool page, not here.
