How credits work
With Thunders, you can perform the following AI actions. Each action consumes a small amount of credit, and your monthly allowance is shared across them all.
Standard action — A single step in a test: clicking a button, typing in a field, navigating to a page, or checking a value
0.01
Mobile step — A single step on a real iOS or Android device
0.05
Thunders AI test creation — AI writes or updates a test case for you
0.05
Visual or accessibility check — AI compares screenshots or audits accessibility
0.10
File comparison — AI compares files content
0.10
Assisted healing — Ambiguous steps get tightened before your test runs. Once it has executed, suggestions get sharper, grounded in what your app actually does.
0.05
Test plan generation — AI reads a PRD or spec and generates a full test plan
1.00
Example: 5 standard actions + 1 visual comparison + 1 accessibility report = 0.05 + 0.10 + 0.10 = 0.25 credits.

The more you commit, the cheaper it gets
A credit is a credit on every plan. What changes is the price you pay for it. Starter credits cost 1,00€ each; Pro credits cost 0,80€. Enterprise has two models: flat fee or volume.
Flat fee. The plan is sized to your test scope and priced for the year. Once the tier is set, nobody watches a credit counter. Your teams run builds, regressions, debugging, and ad hoc executions freely within that scope. Not per seat. Not per run. Nothing to go over.
Volume. Commit to a yearly credit volume and get a per-credit rate that drops as the commitment grows. Expect a steep discount at high volume. Same platform, same features, metered instead of flat.
Not sure which fits? Our sales team helps you pick the right one for your scope and release cadence.
Contact SalesOverage is 1,20€ per credit on every plan. On a flat fee there is nothing to go over. If you are over every month, the next plan up costs less than the overage.

No in-house QA? Use ours.
This is our QA of the future.
From the very first tests, Thunders caught real bugs in our interface — bugs that had slipped through all our standard quality processes.
Before Thunders, all UI testing was done manually. With Thunders, everything is end-to-end automated. Thunders lets us generate tests very quickly and improve the overall quality of our product.
Wassim Jouini
CTO @LegalPlace
Thunders is a whole new testing culture, not just another tool.
Automating our tests was a real challenge that classical automation simply couldn't solve. With Thunders, we were able to automate a hundred tests, with no technical expertise required.
Thunders opens up test automation to non-technical roles. Thunders bridges the gap between code and people. With Selenium, it used to take much longer.
Hanen Khalfaoui
QA Manager @Infopro Digital
What won me over with Thunders was the testing approach, the maturity, and the innovation.
Thunders delivers far greater resilience compared to classical automation. Thunders introduced a new variable in how we respond to RFPs — and it changes our entire economic model.
Today, Thunders is giving us a glimpse of more resilient tests and better maintainability of test suites. We run proofs of concept with Thunders to validate technologies for our clients.
Jean-Olivier Penin
Co-founder @B/Acceptance
Thunders enabled us to put quality and test creation in the hands of the entire product team.
Our PM teams covered 80% of our test scope in just six weeks with Thunders. After just one month, the entire team was up and running.
Tests are executable immediately and the onboarding was genuinely straightforward. Now it's the PMs who write test plans in plain language directly in Thunders.

Frequently Asked Questions
What does the free trial include?
14 days of full Pro access. You get 100 credits to explore every feature, enough for thousands of standard test actions. At the end, choose a plan or your account pauses.
How are credits consumed?
Standard browser actions (clicks, inputs, assertions, navigations) cost 0.01 credit each. Visual comparison and accessibility report actions cost 0.10 credit (10x). Test case creation or updates via Thunders AI cost 0.05 credit. Generating a test plan from a PRD costs 1 credit. Mobile steps cost 0.05 credit each.
Does it get cheaper as we grow?
Yes. A Starter credit costs $1.25, a Pro credit $1.00. Enterprise goes further, in one of two ways: a flat fee sized on your test scope and priced for the year, with no credit counter at all, or a yearly volume commitment with a per-credit rate that drops as the commitment grows. No per-seat fee either way.
How do I estimate what I need?
Tests × steps per test × runs per month. An average test is about 30 steps. 100 tests run 10 times a month is 30,000 steps, or 300 credits: Starter. 250 tests is 750 credits: Pro. Above 1,000 credits a month, talk to us about an Enterprise tier.
Why do mobile steps cost more?
Each mobile step runs on a real device we provision, keep warm and stream back to you live. Hardware costs more than a browser tab. Still cheaper than paying for device slots you don't use.
What happens if I go over my credit limit?
Tests keep running. You're charged the overage rate ($1.50/credit) and notified before charges apply. If you are over every month, upgrading costs less than the overage. Enterprise overage drops with your volume tier, and a flat-fee plan has no overage at all.
What if my team grows past the user cap?
Upgrade at any time, prorated for the remainder of your billing cycle. Enterprise removes seat limits entirely.
Do parallel runs cost credits?
No. Credits decide how much you run. Parallel runs decide how fast it finishes. A 200-test suite costs the same in credits on 2 parallel runs or on 20; it just finishes ten times sooner. Enterprise sets parallelism to match your release cadence.
Can I downgrade from Pro to Starter?
Yes, at the end of your billing cycle. Test runs older than 30 days will no longer be accessible on Starter.
Do unused credits roll over?
No, credits reset monthly. If you consistently have leftover credits, a lower plan may be a better fit.
Is mobile testing included?
From Pro: Android and iOS, physical devices and emulators, device pools in the EU or US.
Can I keep my tests if I leave?
Yes. Enterprise includes a Playwright export of your suite.
We already have Playwright or Cypress tests. Do we start over?
No. Enterprise includes a one-time import of your existing suite.
Is Thunders secure and compliant?
Yes. Thunders is ISO 27001 and SOC 2 certified. Enterprise plans include SSO and custom archiving policies for additional compliance needs. Tests run, and data stays in the EU by default. Enterprise can run self-hosted in your own infrastructure, or hybrid.
