Which might suit you

Framed as requirements, not a verdict. Both descriptions come from the same data.

Consider Planet Plan Sets if…

  • your work is mostly residential

It is for residential solar contractors who need clean, cheap, fast permit drawings and are comfortable owning the engineering judgement themselves. It is not for anyone who needs a PE stamp: the word "stamp" does not appear anywhere on the site, no Professional Engineer is named on the team page, and the company describes itself throughout as a drafting service. It is also not for DIY homeowners by default — those are accepted only case by case.

Consider Symbium if…

  • you need a price you can plan against before talking to sales
  • your work is mostly residential

It is for building departments that must satisfy a state instant- permitting mandate (California SB379, Maryland's Brighter Tomorrow Act) or that want automated compliance across more than rooftop solar, and for contractors, expediters and owner-builders in the jurisdictions where it is live. It is not a design or plan-set tool — it checks and issues, it does not draft — and like any instant-permitting platform its value to an installer is entirely a function of whether their AHJ has adopted it.
