The 302 is commodity; staying current with Meta's and Google's conversion endpoints, identifier formats, and consent rules — which change continuously — is not. Agencies pay a second reason: TLS on a client's branded domain is a different problem from pointing your own DNS at a worker.
REPLACEMENT BRIEF

Can AI replace LnkFlow?
EDITORIAL ANSWERKINDACurated prompt
The redirect is genuinely one sitting — a slug, a 302, a click log, UTM injection, on Workers and KV. The product is the loop back out to the ad platforms: since ATT the browser pixel misses a large share of purchases, so Meta and Google bid on server-side conversion events. Closing that loop means persisting click ids at redirect time, carrying them to a sale days later on another device, posting a Purchase that deduplicates against the pixel, and reversing it on refund — every step failing silently while the dashboard still shows clicks.
Resolve a slug to a destination at the edge, log the click, inject UTMs, pass ad click ids through untouched, and 302.

the prompt
Curated promptBuild me a branded link shortener with click tracking to replace LnkFlow. Requirements:
- Cloudflare Workers via wrangler: KV for the slug lookup, D1 for the click
log. Free tier, nothing to babysit.
- A worker on lnk.mydomain.com/{slug} reads KV, writes the click to D1 inside
ctx.waitUntil so the redirect never waits, then 302s with X-Robots-Tag:
noindex and Cache-Control: no-store.
- Inject UTM params at redirect time from the link's KV record, and pass
incoming fbclid, gclid, gbraid, wbraid, and msclkid through to the
destination untouched.
- Log per click: slug, timestamp, country from request.cf, user-agent,
referer, and those ad click ids. Skip bot user-agents from a pattern list
in one file.
- An /admin page behind one password (wrangler secret) to create links and
show clicks per link per day as a plain table.
- Secrets via wrangler secret, never in wrangler.toml. No accounts, no
third-party analytics, no telemetry.
- Out of scope: posting Purchase events back to Meta CAPI or Google offline
conversion import · stable event_id for pixel dedup, fbc as
fb.1.{timestamp_ms}.{fbclid}, and refund reversal. A silently wrong
conversion feed is worse than none.
- Out of scope: TLS for domains I do not own. My own subdomain is one DNS
record · a client's domain means Cloudflare for SaaS and DCV renewals.
- README: wrangler setup, the KV namespace and D1 database, the DNS record,
and adding the first link.Copy or open in an agent

questions
Can AI replace LnkFlow?
Possibly for a narrower core workflow, but this catalog judgment is not a verified build. Expected gaps include: Purchase events delivered back to Meta CAPI with stable event_id deduplication against the browser pixel, Google offline conversion import keyed on gclid, gbraid, or wbraid. Validate the prompt against your own acceptance criteria before committing.
How much does LnkFlow cost?
LnkFlow is listed at about $10/month (Starter, checked 2026-07-30), or $120 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.
What do I lose by replacing LnkFlow?
Honestly: Purchase events delivered back to Meta CAPI with stable event_id deduplication against the browser pixel; Google offline conversion import keyed on gclid, gbraid, or wbraid; click to lead to sale attribution that survives a multi-day gap, with refund reversal; TLS on a customer's branded domain (Cloudflare for SaaS and 90-day DCV renewals, not one DNS record); per-creator performance and commission reporting. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to LnkFlow?
Yes — Dub (The most complete open-source link platform · analytics, custom domains, and a conversion API. Self-hostable.), Shlink (Self-hosted URL shortener with a REST API, click stats, and QR codes.), YOURLS (The long-running PHP shortener · drop it on any LAMP host and it works.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
