Overview
Firma.dev and Bob's CLI are two very different developer tools, each solving distinct problems. Firma.dev is a pay-as-you-go e-signature API designed for SaaS companies to embed document signing into their applications at a fraction of the cost of traditional providers like DocuSign. Bob's CLI is a locally-installed AI coding assistant that lives in your terminal, providing code review, auto-fix, and personalized AI help while keeping your code on your machine.
