Momentic vs mabl vs Testim: Real AI Software Testing Cost per 10,000 Test Runs in 2026
The short answer: Momentic is the only one of these three with a fully public, self-serve price list; mabl and Testim (now owned by Tricentis) are both entirely quote-gated, and Testim's public pricing page as of mid-2026 lists no dollar figures at all for any paid tier. On Momentic's published credit meter, 10,000 test runs a month (at an average of 10 steps per run) costs about $1,813, and 100,000 runs about $18,688. Reported mabl plan estimates range from roughly $499 to $3,000-plus per month depending on tier, but they cannot be normalized reliably to this article's 10,000-run workload, because no public conversion exists between mabl's cloud-run credits and actual test executions. Testim/Tricentis contracts were reported at $10,000 to $50,000 a year depending on team size — figures this article labels clearly as REPORTED estimates, not vendor-confirmed prices, because neither vendor publishes one.
What each vendor bills, and what is honestly unknown
Momentic (OFFICIAL, momentic.ai/pricing). Credit-based, no per-seat charge: one credit per test step, including AI-generated steps (actions, failure recovery, auto-heal); a typical run is about 10 steps, so roughly 10 credits per run. Free: $0 forever, 2,000 credits a month (about 200 test runs), a hard stop at the limit, unlimited teammates. Pay-as-you-go: $125 a month, 10,000 credits included (about 1,000 runs), no hard cap, overage at $0.01875 per credit beyond that, plus 2 Android and 1 iOS mobile devices and 5 phone numbers for SMS/OTP testing. Enterprise: custom, test-based pricing, adding SAML SSO, SCIM provisioning, audit logs, unlimited mobile session length and a dedicated account manager. Interactive runs in the editor are always free and do not consume credits.
mabl (QUOTE-ONLY / UNKNOWN for official rates; REPORTED for reverse-engineered estimates). mabl's own pricing page publishes no dollar figures; every plan routes to a custom quote. Third-party reverse-engineering as of mid-2026 estimated Starter around $499 a month (roughly 500 cloud-run credits), Growth/Professional at $1,200 to $3,000 a month, and Enterprise starting above $40,000 a year (a Vendr-sourced median). mabl separates execution environments: local and CI-triggered runs are free and unmetered; only cloud runs, meaning tests executed on mabl's own hosted browser infrastructure, draw from a shared monthly credit pool that does not roll over. A team that runs most of its suite in its own CI pipeline and only a minority in mabl's cloud will pay far less than these headline figures suggest, since the meter only applies to the cloud-run share of total test volume.
Testim, now Tricentis Testim (QUOTE-ONLY / UNKNOWN). Tricentis acquired Testim in January 2022, and by mid-2026 its pricing page carries Tricentis branding, lists no dollar amounts for any tier, and routes every inquiry to a sales conversation. The tier names (Community, Essentials, Pro, Mobile) survive only in an FAQ, and the page itself sells by product (Web, Mobile, Salesforce) rather than by tier. Community remains free and is the fallback when any trial ends, making it the only concrete, confirmed price point. Reverse-engineered third-party estimates placed mid-market annual contracts at $20,000 to $50,000 a year for roughly 10-engineer teams, and smaller teams (3–5 engineers) closer to $10,000 a year, with per-seat billing, minimum seat counts, and annual-only commitments as the reported standard structure. An older, possibly outdated public reference showed a Community tier (1,000 runs a month, Chrome only) and an "Essential" tier at $450 a month with unlimited runs, predating the current fully quote-gated packaging; this article does not treat that older figure as current.
Momentic cost by volume
Formula: credits = test runs × 10 (steps per run, ILLUSTRATIVE average); cost = $125 + max(0, credits − 10,000) × $0.01875 above the Pay-as-you-go base, or $0 up to 200 runs on Free.
| Test runs/month | Credits consumed | Momentic cost | Cost per 10,000 runs |
|---|---|---|---|
| 1,000 | 10,000 | $125.00 | $1,250.00 |
| 10,000 | 100,000 | $1,812.50 | $1,812.50 |
| 100,000 | 1,000,000 | $18,687.50 | $1,868.75 |
Momentic's per-10,000-run cost rises slightly with volume, from $1,250 to $1,869, because only the first 10,000 credits are included at the flat $125 rate; everything beyond that is metered at $0.01875 a credit with no further volume discount published.
mabl and Testim: what can and cannot be compared
Because mabl's and Testim's actual rates are not public, this article does not force them into the same per-10,000-run table as Momentic; doing so would present invented precision as fact. On mabl specifically: the reported Starter estimate (~$499/month) is tied to roughly 500 cloud-run credits, and this article has no reliable public conversion between a mabl cloud-run credit and a test execution, nor any way to know what share of a 10,000-run workload would actually be cloud-metered versus free local or CI-triggered execution on mabl. For that reason, this article does not present $499 per 10,000 runs, or any other figure, as a normalized mabl cost per 10,000 runs: official price is QUOTE-ONLY / UNKNOWN, the reported Starter estimate is ~$499/month as a plan floor only, and the exact cost per 10,000 runs cannot be calculated without both the credit-to-run mapping and the cloud-run share, neither of which is publicly available. Testim/Tricentis's reported $10,000–$50,000/year range works out to roughly $833–$4,167 a month for an unspecified run volume, which cannot be converted to a meaningful per-10,000-run figure without knowing the actual run count each of those reported contracts covered.
Concurrency premium
Momentic's published plans do not list a separate parallel-execution surcharge distinct from the credit meter; the Pay-as-you-go tier includes a parallel cloud grid, and mobile device concurrency (2 Android, 1 iOS) is the only explicitly capped concurrency limit at that tier. mabl's and Testim's approach to parallel-execution pricing was not captured in public sources (QUOTE-ONLY / UNKNOWN for both), consistent with their broader lack of published rate cards.
Break-even: human test-maintenance hours saved
Formula: hours needed = monthly cost ÷ loaded hourly rate, with $85 an hour for a QA/SDET engineer (ILLUSTRATIVE). This is a threshold: the tool pays for itself if it saves this many hours of manual test-maintenance and flake-fixing work, not a claim that it will.
| Case | Monthly cost | Hours to break even |
|---|---|---|
| Momentic, 1,000 runs/month | $125 | 1.5 |
| Momentic, 10,000 runs/month | $1,813 | 21.3 |
| Momentic, 100,000 runs/month | $18,688 | 219.9 |
| mabl Starter (REPORTED estimate) | $499 | 5.9 |
| mabl Growth/Professional (REPORTED estimate, midpoint) | $2,100 | 24.7 |
| Testim/Tricentis, small team (REPORTED estimate, midpoint) | $833 | 9.8 |
| Testim/Tricentis, mid-market (REPORTED estimate, midpoint) | $2,917 | 34.3 |
At low and mid volumes, the break-even threshold is a small number of engineer-hours (roughly 1.5 to 35 hours a month across the cases above); at Momentic's 100,000-runs-a-month case, it rises to about 220 hours a month, which is not modest — it is close to a full-time engineer's monthly hours, and a team at that volume should weigh the platform cost against a real estimate of maintenance time saved rather than assume the threshold is easily cleared. None of these figures constitutes a guarantee that a given suite will actually see that much time saved.
Sensitivity
- Which figures are vendor-confirmed versus reverse-engineered. Only Momentic's numbers in this article come from the vendor's own published page; mabl's and Testim's are third-party estimates and should be treated with proportionally less confidence.
- Cloud-run share on mabl. Because local and CI runs are free on mabl, a team's actual bill depends entirely on what fraction of its total run volume is cloud-executed, information this article cannot supply without a specific team's configuration.
- Steps per test run. Momentic's credit consumption scales directly with test complexity; a suite of longer, more AI-heavy tests (more self-healing events, more AI-generated actions) consumes credits faster than the 10-step average assumed here.
- Contract structure on Testim. Reported annual, per-seat, minimum-seat-count terms mean actual cost depends on team size as much as run volume, and this article's figures are anchored to reported team-size bands, not run counts.
Budgeting traps
- Quoting a reverse-engineered figure as a confirmed price. Every mabl and Testim figure in this article is REPORTED, not vendor-published, and should be verified directly with the vendor before budgeting.
- Ignoring the local/CI-versus-cloud split on mabl. A team that assumes its entire run volume is billable may significantly overestimate mabl's actual cost.
- Assuming Momentic's per-credit rate stays flat at scale. The published overage rate applies with no announced volume discount beyond the Pay-as-you-go base.
- Treating Testim's old public tier names as current pricing. The vendor's page no longer publishes numbers for any paid tier.
What to ask before you buy
Ask mabl and Testim/Tricentis for a written quote scoped to your exact run volume, cloud-versus-local execution split, and team size, since neither publishes a rate card. Compare that quote against Momentic's public per-credit rate for the same workload before deciding.
