An interactive evaluation tool for comparing TACOS (Terraform Automation & Collaboration Software) platforms. Compare Spacelift, Env0, Scalr, Terrateam, Terramate Cloud, HCP Terraform, and OpenTaco across 21 weighted criteria — and estimate monthly costs based on your team size, resources, and run volume.

- Evaluation tab — 21 criteria with adjustable weight sliders. Changing weights recalculates and re-sorts platform scores in real time. Expand any platform row to see per-criterion rationales.
- Pricing tab — 3 input sliders (users, resources under management, monthly runs). Auto-selects the cheapest tier per platform. Override tiers manually by clicking them in the expanded card.

All evaluation data lives in a single file: public/evaluation.json
It contains:
criteria— 21 evaluation criteria with default weights (1–5) and categories (Critical / High / Medium / Low / Nice-to-have)platforms— 7 platforms, each with scores (0–3) per criterion, rationale text, and metadatapricing— tier definitions for each platform including base prices, per-unit costs, feature gates, and whether a price is published or estimated
Scores and pricing were researched from public vendor documentation in February 2026.
