Our Philosophy

Why we build
in the open.

01
Trust requires transparency
Tools that manage your servers, monitor your infrastructure and touch your firewall need to be auditable. Closed-source security tools are a contradiction in terms. Every line of Petacomm code is readable, reviewable and forkable.
02
Linux deserves open tools
Linux itself is open source. The ecosystem built on top of it should be too. Proprietary tooling that locks you in defeats the entire philosophy of choosing Linux in the first place.
03
Community makes better software
Bug reports from real sysadmins running real infrastructure are worth more than any QA team. Open issues, public pull requests and community patches make Petacomm tools better for everyone.
04
No paywalls. Ever.
Core functionality will never move behind a paid tier. We sustain ourselves through enterprise support contracts and custom tooling — not by crippling the free version. GPL-3.0 enforces this permanently.
