Quick, free utilities for anyone posting to social — character limits, best posting times, and more. They run entirely in your browser with nothing to install. When you're ready to automate the whole workflow, Oxhype is here.
Each tool is free and instant. Open one and start using it — no account needed.
The posting windows commonly cited for each network, converted from your audience's local time into yours. Pick a platform and where your followers are, and see exactly when to be publishing on your own clock. Free and runs entirely in your browser.
Check your caption against every platform's limit at once. Paste your text and see live character counts for X, Bluesky, Threads, Instagram, TikTok, LinkedIn, and YouTube — and exactly how much room is left on each. Free, instant, and runs entirely in your browser.
Paste one post and see it rendered for X, Bluesky, Threads, Instagram, TikTok, LinkedIn, and YouTube at once — where each feed collapses it behind a “more” link, and where it runs past the hard limit entirely. Free, instant, and runs entirely in your browser.
Paste a caption and see how many hashtags it carries, which ones repeat or won't link, and whether it clears each network's rules — including Instagram's five-hashtag cap introduced in December 2025. Free, instant, and runs entirely in your browser.
Every current upload size and aspect ratio for Instagram, TikTok, YouTube, LinkedIn, X, Facebook, and Pinterest — plus a crop checker that tells you exactly how much of your image each placement will cut. Free, instant, and runs entirely in your browser.
