Frontier GoWild™ Fare Radar — compare pass fares against cash on any route
WildAF is a live subscription SaaS built and operated by Howarth Tech Solutions. It's a fare radar for Frontier Airlines' GoWild™ all-you-can-fly pass: for any route and date, it puts the GoWild fare side by side with the standard, Discount Den, and bundle cash fares — so a pass holder can instantly see whether a given flight is worth burning a GoWild booking on, or whether cash is the better play.
Beyond the head-to-head fare comparison, WildAF surfaces the details that decide a trip: full itineraries with legs, layovers, and distance; a seat-fullness meter derived from Frontier's own per-fare-class bookable-seat counts; a ±3-day fare strip; and an “Anywhere” mode that scans every destination Frontier serves from your home airport at once. It's free to use, with an optional Pro plan at $4.99/mo that unlocks fare-watch push alerts and the deeper trip-planning tools.

A lean, self-contained full-stack build — everything from the fare parser to billing runs in a single stateless-friendly container.
There is no official Frontier API. WildAF fetches Frontier's public booking endpoints server-side, follows their cookie-aware redirects, and extracts the embedded flight-data JSON with a purpose-built parser. Results are cached with date-tiered TTLs (minutes for near-term dates, hours for far-out), persisted to SQLite so restarts stay warm, and kept fresh by a jittered pre-warm sweep of the most-searched routes. The parser is isolated so an upstream shape change is a contained, fixable break — not an outage across the app.
Everything a GoWild pass holder needs to decide when to fly, where, and on which fare.
The engineering that turns an unofficial data source into a dependable product.
With no public API to rely on, WildAF fetches Frontier's live booking endpoints server-side, follows their cookie-aware redirect chain, and extracts the embedded flight-data JSON. The parser lives behind a single normalization layer, so when Frontier changes its response shape the fix is one localized change — the rest of the app keeps running on cached data in the meantime.
Fare freshness is tuned to how volatile a date is: near-term searches refresh in minutes, far-out ones cache for hours. Snapshots persist to SQLite so a container restart stays warm instead of cold-starting, and a jittered ~15-minute pre-warm sweep keeps the most-searched routes hot — which also feeds the Anywhere calendar's historical view.
Fare-watch notifications run on self-contained Web Push (VAPID) with an in-process checker — no third-party notification service. Users subscribe from any device, and the stranded-o-meter reuses the same data to surface escape options when a route is booked solid.
The Pro tier runs on Square subscriptions, verified end-to-end in production (checkout → webhook → automatic account flip), with a real cancellation flow — countdown, days-left, and no-recharge state. Because the HTS Square account is shared across products, all subscription handling is scoped by plan variation so account-wide webhooks are routed to the right product.
Guides and blog posts are plain markdown that go live on push — no CMS. The system generates the sitemap, canonicals, an OG image, and Article/FAQ structured data, and ships a consent-first GA4 conversion funnel (CTA → sign-up → upgrade → checkout). Layover guides for every Frontier base drive organic discovery.
WildAF ships as a CI-built container image deployed to a DigitalOcean droplet behind Caddy (apex + www, automatic TLS), with resource limits, a GET /healthz check, a SQLite backup drop-in, an installable PWA manifest, and a security.txt at the edge. The deployed commit hash shows in the site footer.
WildAF is Howarth Tech Solutions shipping and running its own SaaS end to end — not a demo.
WildAF is what it looks like when we build, ship, and run a SaaS end to end — data pipeline, billing, alerts, growth, and ops. If you have a product idea that needs the same treatment, let's talk. Or go kick the tires on the live app.
