Project and task management decision
Offsitebudget
A competent developer can reproduce the core scenario/estimation workflow, but the vendor’s production flight-cost modeling, hosted polish, and support are nontrivial to match, and the scoped replacement is a multi-week build.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Collect participant locations and inputs; normalize locations and estimate flight costs; model multiple destination scenarios and compute line-item budgets; apply travel policy assumptions and per-person breakdowns; export/share approval-ready budget outputs.
What it still won’t have
- Polish of a production UX (interactive tour, product copy, edge-case polish)
- Any proprietary flight-price modeling or licensed travel-data feeds
- Commercial support and hosted availability SLA
- Built-in payment flows and analytics the vendor may provide
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal OffsiteBudget replacement: use Next.js for the frontend, Node.js (Express) for the API, and Postgres for storage; integrate Stripe for a simple one-time Event Pass purchase (can be mocked). Core features in scope: participant import and normalized location capture; a flight-cost estimator (either a simple distance-based heuristic or pluggable adapter for a third-party flights API); travel-policy templates (hotel per-night, per-diem, allowances); create and save multiple scenarios per event; side-by-side scenario comparison view with per-person and total breakdowns; export budgets to CSV and PDF; shareable read-only view links. Out of scope: building a production-grade flight-pricing engine, advanced itinerary-level quoting, and multi-organization billing. Include input validation, error handling, basic auth, unit tests for API endpoints, and end-to-end test for the scenario creation and export flows.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
