Can TripIt Pro be vibe coded?
Parse user-forwarded reservations into an offline itinerary and calendar
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For TripIt Pro, parse user-forwarded reservations into an offline itinerary and calendar. The hard boundary is live flight alerts, fare monitoring, seat tracking, account integrations, and disruption data, plus proprietary live data and network coverage.

The achievable core
- Parse user-forwarded reservations into an offline itinerary and calendar, map user-entered places, and organize the trip without claiming live proprietary availability.
- Build a focused single-user workflow with real persistence, search, and export.
- A responsive interface with real empty, loading, success, and error states.
The parts a prompt cannot buy
- live flight alerts, fare monitoring, seat tracking, account integrations, and disruption data
- live fare and inventory data
- global routing dataset
- crowdsourced trail intelligence
- The useful dataset is owned, accumulated, or expensive to reproduce.
- Connectors, OAuth flows, and vendor API changes require constant upkeep.
Why people still pay
People still pay for TripIt Pro because travel subscriptions sell current data and confidence during disruption, not just an itinerary list. The recurring cost buys map licensing, fare feeds, reservation access, route freshness, disruptions, geocoding, caching, offline data, and support, not just the visible interface.
The useful dataset is owned, accumulated, or expensive to reproduce.
Connectors, OAuth flows, and vendor API changes require constant upkeep.

Build brief — a focused alternative to TripIt Pro
Context
**TripIt Pro** — Parse user-forwarded reservations into an offline itinerary and calendar. It currently costs $4.08/mo.
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For TripIt Pro, parse user-forwarded reservations into an offline itinerary and calendar. The hard boundary is live flight alerts, fare monitoring, seat tracking, account integrations, and disruption data, plus proprietary live data and network coverage.
This brief describes a focused, single-operator replacement for the part of TripIt Pro that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.
What you are building
Parse user-forwarded reservations into an offline itinerary and calendar, map user-entered places, and organize the trip without claiming live proprietary availability.
Build a focused single-user workflow with real persistence, search, and export.
A responsive interface with real empty, loading, success, and error states.
Requirements
Functional
Modern browser.
User-entered reservations.
Data and integrations
MapTiler or compatible map key.
Optional public transit or weather API.
Each of these needs a real account, credential, or quota. Set them up before writing feature code.
Non-functional
Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
Security: server-side secrets, validated input, and no credentials in the client bundle.
Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
Portability: the operator can export their data and leave without losing it.
Implementation brief
Build a closest honest personal substitute for TripIt Pro in an empty repository.
Use Next.js 15, TypeScript, SQLite, MapLibre GL, and user-supplied map and travel APIs; do not offer alternative stacks.
The core loop is: parse user-forwarded reservations into an offline itinerary and calendar, map user-entered places, and organize the trip without claiming live proprietary availability.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Create trips, days, places, reservations, notes, documents, packing items, and emergency contacts.
Geocode only user-entered places and display them through MapLibre with cached trip-area tiles where allowed.
Parse forwarded reservation text locally into editable fields without logging message content.
Build a day timeline, route overview, conflict warnings, timezone display, and offline printable itinerary.
Allow manual updates for delays and reservations and label all external data with source and timestamp.
Export a complete trip bundle as JSON, calendar file, Markdown, and PDF.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure.
Deliberately leave out live flight, hotel, award, or ticket inventory.
Deliberately leave out commercial turn-by-turn navigation and global offline maps.
Deliberately leave out booking guarantees, disruption rebooking, and traveler support.
Finish by running the tests and listing the exact commands used.
Delivery standard
Inspect the repository first, then write a short implementation plan before writing code.
Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
Add structured logs around every external call and return actionable errors without leaking sensitive details.
Write unit tests for the core logic and one automated test of the main user journey.
Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.
Acceptance criteria
A clean install starts the app using only the README and .env.example.
The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
Tests, type checking, linting, and a production build all pass with no ignored failures.
No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.
Non-goals
Do not build these, and do not claim to have replaced them:
Live flight alerts, fare monitoring, seat tracking, account integrations, and disruption data.
Live fare and inventory data.
Global routing dataset.
Crowdsourced trail intelligence.
The useful dataset is owned, accumulated, or expensive to reproduce.
Connectors, OAuth flows, and vendor API changes require constant upkeep.
What you still own after launch
Secure credentials, rotate secrets, and handle provider rate limits.
Run migrations, backups, restores, and dependency updates.
Test the critical journey after every model, API, or hosting change.
Monitor failures and fix the edge cases a first prompt will miss.
Maintain every third-party integration as APIs and OAuth rules change.
Risk
**Operational risk.** The code is achievable; dependable data, integrations, and ongoing operations are the real cost.
Editorial confidence in this assessment: high. No independent one-shot implementation is linked yet.
