GitLab Duo cost: what you actually pay

Duo Core is 'free' only after you're already paying for Premium or Ultimate, and GitLab has stopped publishing exact prices for the legacy Duo Pro/Enterprise seat add-ons in favor of a new $1-per-credit 'GitLab Credits' meter layered on top.

GitLab Duo requires a paid Premium or Ultimate base subscription - there is no Duo access on the Free tier. In 2024 GitLab published fixed seat-based pricing for Duo Pro ($19/user/mo) and Duo Enterprise ($39/user/mo); the current (2026) official pricing page no longer restates those figures and GitLab's own docs describe current Duo Pro/Enterprise pricing as not publicly disclosed, instead emphasizing the new 'GitLab Duo Agent Platform' billed via pooled 'GitLab Credits' at $1/credit, with Premium and Ultimate customers getting $12 and $24/user/month in credits respectively as a stated limited-time inclusion. Credit consumption per request varies sharply by model choice.

Where the real GitLab Duo cost hides

The sticker is the smallest part of the story. For GitLab Duo, these are the line items that quietly inflate the bill:

  • Duo is gated behind Premium ($29/user/mo) or custom-priced Ultimate - the 'free' Duo Core feature set is really bundled inside a required base-tier upgrade.
  • GitLab Credits are explicitly a 'limited time' inclusion for Premium/Ultimate - the $12-$24/user/month allowance can be reduced or withdrawn, turning a bundled perk into a new metered cost.
  • Credit consumption per request varies about 10x by model (2 requests/credit on Claude Sonnet 4 vs. 20 requests/credit on GPT-5-mini/Claude 3 Haiku), so a default model change burns the pool much faster.
  • Legacy Duo Pro/Enterprise seat add-ons (historically $19 and $39/user/month) still exist per GitLab's own docs, but current pricing isn't publicly listed, so renewals can lock in stale, unverified per-seat rates.

What an audit finds on GitLab Duo

Auditors frequently find Duo Pro/Enterprise seats purchased for an entire engineering org when GitLab Credit usage data shows only a fraction of those seats ever triggered an agentic request, on top of Premium/Ultimate upgrades bought specifically 'to get Duo' that under-use both the base tier and the credit allowance.
