GAGEtrak and GageList are the two most-searched names in calibration management software. This is a straight, three-way comparison of how they stack up against each other — and against CalibrationOS, a cloud-native option with a free tier that includes uncertainty budgets and Gage R&R. Pricing, free tiers, compliance coverage, and migration paths are below.
| Feature | CalibrationOS | GAGEtrak | GageList |
|---|---|---|---|
| Free tier | Yes — 25 assets, 1 user | No | Yes — limited assets |
| Starting paid price | $49/mo (250 assets) | ~$79/mo per user | ~$39/mo |
| Architecture | Cloud-native SaaS | Legacy desktop + web version | Web-based SaaS |
| Per-seat licensing | No — priced per plan | Yes — per user | Tiered |
| REST API & webhooks | Full REST API + webhooks | Limited; import/export | Limited (paid plans) |
| Measurement uncertainty (GUM / ISO 17025) | Built-in uncertainty budget calculator | Basic tracking | Not available |
| Gage R&R / MSA studies | Integrated (ANOVA, X-bar/R) | Requires separate software | Not available |
| OOT investigation workflow | Guided workflow + impact analysis | Basic flagging | Basic flagging |
| Audit trail & e-signatures (21 CFR Part 11) | Immutable, hash-chained audit log | Audit trail with e-signatures | Basic change history |
| Compliance coverage | ISO 17025, AS9100, FDA 21 CFR 11, ISO 9001, IATF 16949 | ISO 9001, 21 CFR Part 11 | ISO 9001 (basic) |
| Free interactive tools | Uncertainty, Gage R&R & interval-optimizer calculators | No | No |
| Time to first record | Minutes — any browser | Install & configure | Minutes — any browser |
You're an established shop already standardized on GAGEtrak, have heavily customized workflows around it, or require an on-premise desktop install. Its 35-year track record and mature feature set are real — but expect per-user pricing, no free tier, and a separate tool for Gage R&R.
You're a very small lab that needs basic, web-based instrument tracking and scheduling on a tight budget, and you don't need uncertainty budgets, Gage R&R, or deep ISO 17025 / AS9100 compliance automation.
You want a free tier that already includes GUM uncertainty budgets, integrated Gage R&R, guided OOT investigations, and a hash-chained audit log — plus a full REST API and AS9100 / ISO 17025 / FDA 21 CFR Part 11 coverage as you grow. It's the modern, cloud-native option for labs that want compliance depth without the per-seat bill.
It depends on the lab. GAGEtrak is the long-established option (35+ years) with deep, mature calibration tracking and a per-user, no-free-tier pricing model — strong for established shops that already run it. GageList is lighter, web-based, and has a limited free tier, which makes it popular with very small labs starting out. Neither includes GUM-compliant measurement uncertainty budgets or integrated Gage R&R/MSA — if you need those for ISO 17025 or AS9100, both fall short and you'd buy a separate tool.
Yes. CalibrationOS offers a free tier (25 assets, 1 user) that includes capabilities neither competitor provides for free — built-in uncertainty budgets, Gage R&R, guided out-of-tolerance investigations, and a hash-chained audit log with electronic signatures. There's no credit card required to start.
GAGEtrak offers basic uncertainty tracking but not a full GUM-compliant uncertainty budget calculator, and Gage R&R requires separate software. GageList includes neither at any tier. CalibrationOS builds both directly into the calibration workflow following ISO/IEC Guide 98-3 (GUM) and standard ANOVA / X-bar & R methods.
Yes. CalibrationOS imports instrument records, calibration history, due dates, and locations from CSV exports produced by either tool. Most GageList migrations finish in 1–2 weeks; GAGEtrak migrations typically run 4–6 weeks including a parallel-running period to validate data.
For accredited labs and aerospace/defense quality systems, the deciding factors are uncertainty budgets, traceability, and audit-ready records. CalibrationOS is AS9100-native and covers ISO 17025, FDA 21 CFR Part 11, ISO 9001, and IATF 16949 with automated compliance reporting — areas where GAGEtrak provides partial support and GageList provides only basic ISO 9001 features.
