Top 23 File Upload Open-Source Projects

ShareX
ShareX is a free and open source program that lets you capture or record any area of your screen and share it with a single press of a key. It also allows uploading images, text or other types of files to many supported destinations you can choose from.
I made sure to document every step of the way via screenshots to ensure I could test enabling and disabling certain features. The screenshot tool I use on Windows is called, ShareX, and I find it extremely useful with regards to pointing out certain elements in an image.

-
Project mention: Released a Library for Synchronous Execution of Asynchronous Processes in JS/TS | dev.to | 2024-12-16
Accel Record is also designed to be similar to Ruby on Rails' Active Record in terms of usability, and one of the things I want to achieve in the future is to create a library like CarrierWave. CarrierWave allows you to save images to external storage services (such as AWS S3) when saving records, and to achieve this with Accel Record, it is necessary to execute asynchronous processes such as image uploads synchronously. I expect that this process can be executed faster by using worker_threads instead of subprocesses.

Project mention: Show HN: I Built ImgFiber-Better Image Optimizer. Free No Limits | news.ycombinator.com | 2025-04-06
What am I missing about the 2.8mb image not reducing to 698kb in the example? I downloaded https://www.imgfiber.com/compare/original.jpg and dragged it into the try-it-now section - says it's now 1.3mb.
That's worse than Squoosh's default 897kb (https://squoosh.app/editor), though better than CompressorJS's default 2.21mb (https://fengyuanchen.github.io/compressorjs/).

Project mention: Magic Wormhole: get things from one computer to another, safely | news.ycombinator.com | 2024-08-17 -
https://github.com/shrinerb/shrine/discussions/665
I've never personally encountered this, but I've seen other HN contributors mention it.
From what I can tell, unlike mongo, some postgres queries will try to update the entire JSONB data object vs a single field. This can lead to race conditions.
