Short answer. If you want a broad, established test practice across web, mobile and APIs, with permanent, audit-ready evidence, mabl itself is built for that. ShipperAG is a narrower job: it fits tech and product teams shipping their own product who want one release checked against their requirements, with evidence to approve it. It only tests the web, in Chromium.
What mabl is
mabl is an agentic testing platform for engineering and quality teams, and says it has been "built on AI since 2017". Its agents create, run, analyse and maintain tests across web, mobile and APIs. As of September 2026:
- Test creation. QA and business users build end-to-end tests for web and mobile by pointing and clicking or by writing in natural language, starting from a plain-English description, a user story or a Jira ticket. Developers can extend tests with JavaScript and Appium snippets and build on existing Playwright tests (low-code testing).
- Maintenance. Tests heal themselves for routine changes. For bigger recoveries, mabl shows what it would change and waits for approval.
- Coverage. Web, mobile, API, accessibility and performance testing, plus email and document checks; the pricing page lists mobile app testing as an add-on (mabl pricing).
- Evidence. Traceability from requirements to results. Every test step keeps screenshots, DOM snapshots, network logs and the agent's reasoning, time-stamped and retained permanently for passing and failing runs alike (evidence). Dashboards show quality scores across workspaces, with audit trails (agentic testing).
VentureBeat reported in November 2021 that Boston-based mabl, founded in 2017, had raised a $40 million Series C led by Vista Equity Partners. mabl's investor page says it has raised $77M in total, and it runs a partner programme that includes consulting and testing firms.
Why teams look for a mabl alternative
mabl is designed for teams that build and run a lasting test practice. Teams that look for an alternative often want each release judged against their requirements without building that practice first.
- A suite to build first. Even with AI help, mabl's model is a suite that people direct, review and keep. A startup, or a team without dedicated QA, may not have the time to build and run that suite before its next release.
- Evidence for a release decision. mabl's evidence is built for auditors, regulators and other stakeholders, with traceability from requirements to results. A team deciding whether to ship often needs something narrower: this release, checked against these requirements, with open questions and gaps stated plainly, ready to sign.
- What "correct" means for your product. Your requirements, design system and business rules define what counts as a bug, and each release has to be judged against them.
In fairness, mabl already tests from requirements and keeps strong, permanent evidence, and its plans include unlimited apps, environments and workspaces. The differences are who the output is for, and whether you build a suite first.
mabl vs ShipperAG at a glance
mabl helps teams build, run and maintain automated tests; ShipperAG checks each release and hands your team evidence to sign. Here is how they compare as of September 2026.
| Aspect | mabl | ShipperAG |
|---|---|---|
| Built for | Engineering and quality teams, including financial services, healthcare and retail | Product and engineering teams that need evidence to approve each release |
| Approach | Agentic testing platform: agents create, run, analyse and maintain tests | AI QA specialists check each release against your requirements, design system and business rules |
| Who writes and maintains tests | QA, business users and developers author tests (low-code, natural language or code); agents maintain them, with approval for bigger changes | No suite to write: a coordinator picks the specialists each change needs, within your limits |
| Evidence and sign-off | Requirements-to-results traceability; screenshots, DOM snapshots, network logs and reasoning for every step, kept permanently | Verified, Issue found, Needs input and Not covered, sealed in an evidence ledger, plus a shareable report for sign-off |
| Coverage | Web, mobile, API, accessibility and performance; mobile app testing listed as an add-on | Built around 13 quality areas; designed for preview and staging URLs, and to run inside CI pipelines |
| Separate projects | Unlimited apps, environments and workspaces | One workspace per client team, with projects inside it |
| Pricing model (as published) | Prices not published: quote-based, with credits for cloud runs and unlimited local and CI runs; 14-day free trial | From $149 a month, after a free 45-day trial |
| Availability | Available now | Private pilot (waitlist) |

mabl pricing, as published
mabl does not publish prices. As of September 2026, its pricing page offers a quote tailored to each organisation, with no setup fees:
- Credits are used by cloud test runs, from a starting point of 500 credits a month. Local test runs are free.
- Plans include unlimited local and CI test runs, unlimited apps, environments and workspaces, and unlimited participant licences.
- Mobile app testing and a technical account manager are add-ons.
- There is a 14-day free trial.
If you are comparing costs for a mabl alternative, ShipperAG publishes its price: from $149 a month for 20 release checks, after a free 45-day trial; it is in a private pilot with a waitlist.
Where ShipperAG is different
mabl helps a team build a lasting test practice. As a mabl alternative, ShipperAG is designed for a narrower job: check one release against your requirements, re-check every finding, and hand your team evidence to sign.
- Your requirements are the test plan. You add your requirements, design system or brand tokens, business rules and API docs, and the coordinator picks the specialists each change needs, within your limits, from the team of AI QA specialists ShipperAG is built around.
- Real checks decide. A real browser, HTTP and API calls, automated accessibility rules and visual comparison against design tokens. A language model's opinion alone can never mark anything verified.
- An independent re-check. The verifier re-runs every finding in a fresh session before it reaches the report.
- Four honest states. Verified, Issue found, Needs input and Not covered. Unclear or contradictory requirements become a precise question, not a guess.
- A report people can sign. Results are sealed in a hash-chained ledger. A person on your team signs off, or shares a self-contained HTML report with the stakeholders who approve the release; our UAT sign-off template shows what that approval should record.
- One workspace per team. ShipperAG is built around one workspace per client team, with projects inside it, so each product keeps its own context, builds, evidence and reports.
Accessibility checks are automated WCAG rules; our guide to AI accessibility testing explains what automated checks catch and what still needs a person.
When mabl is the better choice
Not every team needs a mabl alternative. mabl is the better fit when a team wants a broad, established testing platform for a product it will run for years.
- A maintained regression suite across web, mobile and APIs.
- Audits and regulation. You need traceability from requirements to results, with evidence kept permanently.
- Mixed teams. QA and business users author tests without code, and developers extend them.
- Support at scale today. A 14-day trial, 24x5 live support in English and Japanese, and a customer success manager.
- Performance and API testing in one place, alongside your UI tests.
The two can also sit side by side: a mabl suite guards regression across the product, while per-release checks cover what changed against your requirements.
What ShipperAG does not do
ShipperAG is new, and it is not right for every job:
- It is not generally available or self-serve. It is a private pilot with a waitlist: teams start with a free 45-day trial with up to 20 release checks, and paid plans start at $149 a month.
- It does not replace a maintained regression suite on a long-lived product. It is designed to run alongside one.
- It only tests targets you own or have written permission to test, and it stays inside the hosts you allow.
Other mabl alternatives and competitors
ShipperAG is not the only mabl alternative. Other options teams compare with mabl include QA Wolf and Momentic.
- QA Wolf sells a self-serve AI platform that writes Playwright and Appium tests, and a managed service that guarantees 80%+ automated test coverage. See our QA Wolf alternative comparison.
- Momentic is an AI testing platform where you describe end-to-end tests in plain English, and it runs and updates them. Its published plans start with a free tier. See our Momentic alternative comparison.
