Side-by-side comparison of AI visibility scores, market position, and capabilities
Pentest as a service platform connecting enterprises with vetted researchers for on-demand, time-boxed security tests delivering results in days. Eliminates multi-month fixed-scope engagements; serves security-conscious SaaS companies and regulated industries.
About
Cobalt.io is a pentest as a service platform that replaces the traditional engagement model for penetration testing — multi-month sales cycles, fixed-scope contracts, and point-in-time PDF reports — with an on-demand platform that connects companies with a curated network of vetted security researchers to run targeted, time-boxed pentests that deliver results in days rather than weeks. The platform's core innovation is the application of talent marketplace mechanics to security testing: companies define their test scope and objectives through the Cobalt platform, and vetted pentesters with relevant expertise are matched to the engagement, perform testing, and submit findings through a structured findings interface that delivers actionable vulnerability data in real time rather than in a post-engagement report delivered weeks after testing completes.
Open-source offline-first API client with git-native Bru file storage; solo-founded, declined 8 VC offers, competing with Postman and Insomnia for developers seeking privacy-respecting local API testing tooling.
About
Bruno is an open-source API client and testing tool — a lightweight, offline-first, git-friendly alternative to Postman and Insomnia — enabling developers to explore, test, and document APIs with collections stored as plain-text Bru files in the project filesystem rather than in cloud-synced proprietary formats. Created by a solo founder in 2022 and growing to a 9-person team by late 2024, Bruno operates with an unusual philosophy: the founder publicly declined 8 venture capital offers to preserve product freedom and build toward profitability, with the core Bruno client remaining free and open-source (MIT license) while the Golden Edition provides enterprise features for commercial revenue. Pro and Ultimate paid editions launched in 2024.
