The short version

  • Only STACK Construction Technologies has a free tier, so it costs nothing to try first.
  • Each has a real cost: Buildots tracking depends on a BIM model maintained at construction level of detail; on a job where the model is stale or was never built for coordination, the comparison degrades and much of the value disappears.; STACK Construction Technologies takeoff and Estimate is priced per user at $249 per user per month, so cost scales linearly with estimators
  • They diverge on capability: Buildots covers Hard hat 360 capture, STACK Construction Technologies covers Digital takeoff.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Buildots

  • Tracking depends on a BIM model maintained at construction level of detail; on a job where the model is stale or was never built for coordination, the comparison degrades and much of the value disappears.
  • The data only arrives if someone walks the site every week with the camera, so coverage decays quietly when the site team is under pressure, exactly when the reporting is most needed.
  • Pricing is per project rather than per seat and includes hardware, so a contractor cannot roll it out cheaply across a portfolio of small jobs and it is uneconomic below a certain project value.
  • It reads interior fit-out and repetitive vertical work far better than structure, groundworks or external envelope, so a large fraction of a project's programme is outside what it can score.
  • Making progress objective creates commercial friction with subcontractors whose valuations have historically been negotiated, and contractors who deploy it without addressing that in the subcontract get pushback rather than adoption.

STACK Construction Technologies

  • Takeoff and Estimate is priced per user at $249 per user per month, so cost scales linearly with estimators
  • The full platform combining takeoff, estimating and field management starts at $298 per user per month
  • Field and project management is sold as a separate Build and Operate product starting at $49 per user per month rather than bundled with takeoff
  • The Build and Operate product offers only a two-week free trial, with the free version limited to Takeoff and Estimate
