openSenseMap vs wttr.in
openSenseMap is the open, non-profit citizen-science platform behind the University of Munster's senseBox project, serving live and historical readings from thousands of crowdsourced environmental sensor stations worldwide, covering not just temperature/humidity but also particulate matter, noise and other phenomena. Reading data is fully open and keyless (accounts are only needed to register or post data from your own senseBox), and the full historical archive is separately mirrored on an archive subdomain.
wttr.in returns weather reports as ASCII art directly to curl, wget, or a plain browser request, so there's no client UI to build. It's a standalone open-source Go service with plain-text, colorized ANSI, PNG, and JSON output modes, and needs no signup or API key.
