bsns probe
Checks a domain's DNS, website, TLS certificate, security headers and email setup (SPF, DKIM, DMARC). You get fixes in plain English, and the raw records for whoever looks after your domain.
bsns tools
Free tools for the technical side of running a business.
Open source. No account, no ads, no tracking.
Web
bsns accessibility
Finds the problems behind most website accessibility complaints: images without alt text, form fields without labels, links with no name, and zoom that is turned off.
Web
bsns QR
Makes QR codes for a link, Wi-Fi network, contact card, event, phone number or place. The codes are made in your browser and never expire, so nothing breaks if you stop visiting.
iPhone, iPad, Android, Mac
bsns.SSH
An SSH and mosh client whose keys stay in your device's secure hardware or on a security key, so they cannot be copied off. Tabs, SFTP, port forwarding, tmux at a glance, and encrypted sync through storage you choose.
Why these are free
We use them ourselves.
bsns.cc makes software that runs small businesses. Running one comes with technical chores nobody signed up for: a domain that has to keep working, email that has to land, a website everyone can use, a code on the counter, a server to look after. We built these tools for those chores, and we would rather you had them too.
Every tool is open source, so you can read exactly what it does. None of them needs an account, the web tools don't save your results, and bsns.SSH has no server at all. If you want the rest of the business in one place, that is what bsns.cc is for.
