Common questions

Everything you'd ask before switching from Bitly.

How does SmartLink achieve sub-5ms redirect latency?

The redirect engine is written in Go with Fiber (fasthttp-based). Hot links live in an in-process Ristretto LRU cache (0.05ms). Cold links hit Redis (0.5ms). PostgreSQL is only queried on cold-cache misses and the result is immediately warmed.

Can I use my own branded domain (e.g. link.brand.com)?

Yes. Add a CNAME record in your DNS pointing to your SmartLink server. Verify ownership with a DNS TXT token and SSL is auto-provisioned via Let's Encrypt. Bitly charges $35/mo for this; SmartLink includes it from $9/mo.

Is SmartLink GDPR compliant without cookies?

Yes. We never store raw IP addresses. Client IPs are salted and SHA-256 hashed in-memory for 24-hour unique visitor counting, then discarded. No tracking cookies are set on any visitor's device.

Can I self-host SmartLink?

Absolutely. The entire stack is a Docker Compose monorepo — Nginx, Go redirect engine, Go API, Go analytics worker, Next.js dashboard, Astro marketing site, PostgreSQL 16, and Redis 7. Deploy to any VPS with a single command.

How does A/B split routing work?

Assign a percentage (e.g. 30%) to a variant URL. SmartLink uses a deterministic SHA-256 hash of the visitor's IP + slug to consistently assign visitors to the same variant across sessions — without cookies.
