How to Deploy a Self-Hosted WAF Alternative to Cloudflare
A self-hosted WAF means the inspection engine runs in your own environment, not a vendor's cloud. For teams that want control, privacy, or predictable cost, that is the whole point — and SafeLine is built exactly for this.
What "self-hosted" buys you
- Traffic never leaves your network for inspection.
- No per-request billing.
- Your own dashboard, logs, and policy.
SafeLine specifically
SafeLine is deployed as a container that acts as a reverse proxy. Its semantic-analysis engine inspects each request for attack intent, blocking SQLi, XSS, and automated abuse before it reaches your app. The web console lives at https://<ip>:9443.
Comparing to SaaS WAFs
SaaS WAFs (Cloudflare, AWS WAF) win on zero-infra and global edges. Self-hosted wins on control and cost. SafeLine narrows the operational gap with a fast container install and a free Community Edition (10 apps / 800 QPS).
FAQ
What are the hardware requirements?
1 CPU, 1 GB RAM, 5 GB disk — modest.

Yes; place it as the inspection tier before your upstreams.
How do I monitor it?
The dashboard shows real-time logs and alerts; you can also export for your own SIEM.
