8 tools matching “live”
A virtual whiteboard with a hand-drawn feel. Sketch diagrams, wireframes, and flowcharts, collaborate live, and export to PNG or SVG. Runs entirely in the browser and drawings stay local unless you share them.
Spin a 3D globe and tune into live radio anywhere on Earth — lo-fi from Jakarta, talk radio from Reykjavik, cumbia from Bogotá. No sign-up: click a green dot and listen.
A PDF and EPUB reader that lives entirely in your browser: highlight both formats, keep a per-book journal, read offline. No install, no account, no uploads — files stay on your device.
Paste a domain and get an email-deliverability health verdict: DNS records, SPF/DKIM/DMARC authentication, and blacklist signals — in the browser, no signup, no mailbox access, no test sends.
Build and debug regular expressions with live matching, an explanation panel that decodes every token, and a searchable reference. Supports PCRE, JavaScript, Python, and more flavors.
A live 3D globe of developers coding right now, with stats per repo, file, and language. Connect your editor and your dot lights up — or just spin the planet and watch the world build. Free.
A hypnotic animated globe of live wind, ocean currents, and air quality, rendered from real forecast data. Drag to spin, scroll to zoom, and lose ten minutes watching the planet breathe.
A falling-sand physics toy: pour sand, water, fire, and plants, then watch tiny ecosystems collide. Every pixel obeys simple rules; somehow the result feels alive.
