Overview
SafeLine is a modern Web Application Firewall (WAF) that sits in front of your web services as a reverse proxy and inspects traffic to block common attacks such as SQL injection, XSS, and OWASP Top 10 threats. It features a web-based dashboard for configuring protection rules, viewing attack logs, and managing upstream services. Built by Chaitin Technology, it uses semantic analysis for detection rather than simple pattern matching. Deploys via Docker Compose with a live demo available.
Where it falls short of Heroku
- Not a PaaS replacement in the traditional sense; focused solely on WAF/security, not app deployment
- Bot management and advanced DDoS protection lag behind commercial WAF offerings like Cloudflare
- No built-in CDN or global edge network for performance benefits
- API security coverage (GraphQL, gRPC) is more limited than enterprise WAF solutions
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
