ApiFlash vs ShareX

ApiFlash is a cloud API for generating website screenshots, including full-page and mobile captures. Requests go through a unique HTTPS endpoint using an access key and GET or POST methods. Google Chrome instances render pages, with controls for viewport, CSS-element capture, JavaScript injection, headers, cookies and time zones. Images can be returned as PNG, JPEG or WebP, or exported to Amazon S3 and compatible storage. The API runs on AWS Lambda and applies a leaky-bucket limit of 20 requests per second, with bursts up to 400. Each capture uses a separate Chrome instance that is discarded with its temporary data. Plans include 100 screenshots free; paid plans start at $7 a month for 1,000 screenshots, with higher-volume plans available. Strict bot protections can block captures, and ApiFlash recommends supplying a proxy in that case. Custom enterprise plans include managed proxies and IP geolocation. Support is available by email and live chat.

ShareX is a free, open-source screenshot and screen-recording tool for Windows. It captures the full screen, a selected region, the active window, a scrolling page, or a monitor, and can record video and GIFs. Its image editor provides annotation and redaction tools, while OCR recognizes text in images. After a capture, ShareX can copy, open, shorten, or share links, and supports many upload destinations as well as custom uploaders. It also lists browser extension support and supports many languages, including English, Hindi, and Spanish. ShareX requires no account and has no advertisements. The ShareX Team maintains the software, which has had more than 18 years of active development and over 33 million downloads worldwide. The maker describes its approach as privacy first. The website provides documentation guides and links to related GitHub projects. ShareX is available for Windows.
