This post introduces BunkerWeb, an open-source web application firewall (WAF) that is gaining attention among tech enthusiasts and developers. The project has mixed reception, particularly around its 'pro' features, leading to discussions on whether it adheres strictly to open-source principles or operates as an open-core model. Several commenters express concerns about commercial viability, integration with existing systems, and potential privacy issues due to telemetry. There's also a mention of alternatives like Cloudflare's free-tier offering and CrowdSec, indicating that while they serve similar purposes, they come with their own trade-offs in terms of privacy and functionality. Furthermore, questions arise about performance impacts and compatibility with existing web configurations, highlighting the technical depth users are interested in.
