ToolsTray is a collection of 130+ small, free tools that each do one job: compress a PDF, remove an image background, convert HEIC to JPG, trim a video, diff two JSON files, work out a loan payment. Open the page, do the task, download the result โ no account, no upload queue, no watermark. Everything runs in your browser: files are processed on your device rather than uploaded, so big files finish fast. It covers the same ground as TinyWow, iLovePDF, Smallpdf, and remove.bg โ PDF, image, video, audio, text, developer, calculator, and generator tools โ without signup walls or daily limits.
ExpressJS ToolsTrayToolsTray's answer:
It started with a solo developer's irritation at what "free online tool" actually means: upload your file, make an account, hit a paywall โ for a ten-second job. Browsers quietly became powerful enough to do these jobs themselves โ WebAssembly for codecs, WebCodecs for video, small AI models that run locally โ so I built the tool site I wanted: open the page, do the task, download the result. It's grown to 130+ tools, and every one of them stays free.
ToolsTray's answer:
Everything runs in your browser โ all 130+ tools. Compress a PDF, remove an image background, trim a video, transcribe audio: there's no upload, no queue, no server doing the work. Modern browsers can handle all of it through WebAssembly, WebCodecs, and small on-device AI models, so the page you open is the whole tool. That's also why there are no file-size meters or daily limits โ there's no server bill to protect.
ToolsTray's answer:
No signup walls and no metering. TinyWow, iLovePDF, and Smallpdf are good tools, but the free tiers push you toward an account or a daily cap right when you're mid-task. ToolsTray is free with no account for every tool. Big files are often faster too, because a 200 MB video doesn't get uploaded anywhere โ it's processed on your machine. And it's one site for tasks that usually take five: PDF, image, video, audio, converters, calculators, and developer tools together.
ToolsTray's answer:
People with one task to finish right now: office workers wrangling PDFs and spreadsheets, students formatting and converting coursework, creators resizing images and cutting clips, and developers formatting JSON, testing regex, or diffing files. The site has a hub for each of those four groups.
ToolsTray's answer:
TypeScript and Astro, shipped as a fully static site on Cloudflare โ there's no backend at all. The tools compute with WebAssembly (image codecs, PDF compression), pdf-lib and pdf.js for PDF work, WebCodecs and the Web Audio API for video/audio, and on-device AI via Transformers.js + ONNX Runtime โ Whisper for transcription, Florence-2 for image captioning, U2Net for background removal โ all running in the browser.

Casbin provides an external policy engine if your permission model grows complex enough that a centralized JS function becomes hard to maintain.

Many REST frameworks also ship with limited security controls enabled by default. Express.js , a minimal web framework, does not include rate limiting or input validation out of the box and relies on middleware for these concerns. Django REST Framework includes throttling features, but they are not enabled by default. - Source: dev.to / 3 months ago
Nearly every server-side web framework uses some version of MVC. Django calls it MTV (Model-Template-View), Rails follows classic MVC, and Express.js gives you the building blocks to implement your own version. - Source: dev.to / 3 months ago
