AI Tools · 6
ChatGPTThe default chatbot. The free tier is genuinely useful, but there is no free API and no way to remove the usage caps.
ClaudeBest free tier for long documents. If you regularly paste 50-page PDFs, this is the one to start with.
GeminiThe most generous free tier of the big three, and the only one that reads your Google Docs and Drive natively.
MidjourneyNo free tier at all. The free trial ended in 2023 and has not returned, so ignore any guide that says otherwise.
PerplexityAnswer engine, not a chatbot. Worth it if you need sources you can click, and the free Pro-search allowance is small.
PoeOne subscription, many models. The free daily points are enough to compare models before committing to any of them.
Web & Dev · 12
Base64 Encoder / Decoder built-inEncode and decode Base64 with correct UTF-8 handling.
Case Converter built-inSwitch text between camelCase, snake_case, kebab-case, Title Case and more.

URL Encoder / Decoder built-inPercent-encode URLs and query strings, or decode them back.

Can I UseThe reference for browser support. Faster than reading MDN compatibility tables when you just need a yes/no.
CodePenBest free place to sketch front-end ideas. Free accounts can only publish public pens, which is fine for demos and bad for client
DevDocsOne search box across a hundred documentation sets, works offline. The single best free tool on this list for daily development.
GitHubFree private repos and 2,000 CI minutes a month. For a solo developer that is a complete toolchain at zero cost.
Stack OverflowStill the fastest answer for error messages, as long as you read the dates. Anything older than about three years may describe a f

AlibabaFree to browse and request quotes. The cost is minimum order quantities, not the platform.
FiverrFree to browse, and often cheaper than doing it badly yourself. Watch the buyer service fee, which is added at checkout.
ShopifyNo free plan. A $1/month trial for the first months, then a real subscription — budget for it before you build.
WooCommerceThe plugin is free forever. The store is not — hosting, domain and a couple of extensions are unavoidable costs.
Image & Media · 5
CanvaThe most useful free design tool for non-designers. 5 GB of storage, no watermark on your own designs, and a huge free template li
FigmaFree plan gives you three collaborative files. Enough for a small project, not enough for a client workflow.
Remove.bgFree previews at low resolution, paid credits for full-size output. There is no free full-resolution path.
TinyPNGBest compression quality per byte. Free web tool handles 20 images at a time, 5 MB each.
UnsplashFree photos you can use commercially without attribution. The catch is that everyone else uses them too.
File Conversion · 5
Word & Character Counter built-inCount words, characters, sentences and reading time as you type.
CloudConvertThe most reliable free converter for odd format pairs. 25 conversions a day, up to 1 GB per file.
ConvertioWider format list than most, tighter free limits: 100 MB per file and a short daily conversion window.
PDF24 ToolsGenuinely unlimited free PDF tools, including an offline installer. The most generous tool on this list.
TinyURLFree, no account, no expiry, no click limits. The least annoying link shortener still running.
Filter by what matters
If you are looking for a specific constraint rather than a category, the filter pages cut across all of them: no signup, no watermark, open source, works offline.
