JustInBrowser's answer

Everything runs entirely in your browser. There is no signup, nothing is uploaded to a server, and exports have no watermark. It puts 20+ developer and design tools (API tester, JSON viewer, regex tester, cron generator, image crop/compress/annotate, favicon generator, and more) in one fast place, so you do not need to install an app or hunt for a different site for each task.

EXdeck.xyz's answer:

EXdeck generates real, fully editable files — not locked previews or watermarked exports. You get native .pptx, .xlsx, and document formats you can open directly in PowerPoint, Word, or Excel, with no paywall blocking the download. It's built mostly client-side, keeping it fast and affordable, and includes Collaboration Mode with owner/editor/viewer roles and change history — so teams can work on files together, not just generate them solo.

JustInBrowser's answer

Developers, QA and test engineers, web designers, students, and indie makers who need a quick, no-fuss tool without installing software, creating an account, or uploading private files.

EXdeck.xyz's answer:

Students, early-career professionals, and small teams who need to quickly produce polished presentations, documents, and spreadsheets but don't want to pay for expensive software or deal with restricted exports. Also useful for solo founders and freelancers who need professional-looking files fast.

JustInBrowser's answer

It is genuinely free with no limits and no account, and it is private by default because your data never leaves your device. Most free tool sites either make you sign up, upload your files, stamp a watermark on the result, or push you to a paid plan. This does none of that. It loads instantly, works on any browser, and covers many everyday tasks in one place.

EXdeck.xyz's answer:

Many AI presentation/document tools give you a preview and then charge extra or watermark the file when you try to export. EXdeck's exports are real and unrestricted from the start. It also covers more ground in one place — presentations, documents, spreadsheets, resumes, and file conversion — at $1.99/month, well below what most competitors charge for editable exports alone.

JustInBrowser's answer

I kept needing small tools during everyday work: test an API, format some messy JSON, crop a screenshot, make a favicon. Every time I either had to install an app, sign up, or paste private data into a random website I did not fully trust. So I built the tools I actually reach for into one site that runs client-side, keeps your data on your device, and never asks you to register.

EXdeck.xyz's answer:

EXdeck started as a solo project to solve a personal frustration: most AI file-generation tools either lock the real export behind a paywall or produce files that aren't truly editable. It's built and maintained by a single developer, with a focus on shipping real, usable output rather than flashy demos.

This one's tricky, because it's a free public tool with no named enterprise customers. Honest options: leave it blank, or list user types like this:

Next.js (React) and TypeScript, styled with Tailwind CSS, shipped as a fully static, client-side site. The image tools use the HTML5 Canvas API, and a lightweight Supabase backend powers the feedback widget. No server processes your data at runtime.
