Spec2RunAI vs testRigor: two ways to run tests in plain English.
Both tools let people who are not automation engineers write tests in English and run them. The difference is what the test becomes once it is stored, and that decides who maintains it, what it costs per run, and what the evidence shows. We build Spec2RunAI, so weigh this accordingly; every statement about testRigor is taken from testRigor’s own public site and documentation on the date above, and we say plainly where testRigor is the better choice.
Last reviewed 11 October 2026. Every testRigor statement is traced to a numbered source in the source list at the foot of this page. Not independently tested.
What the two tools agree on.
Tests are written in English rather than code. Manual testers, analysts, and product owners can author and run them. Both accept existing manual test cases as input: testRigor’s site says “Paste or import your existing manual test cases into testRigor” and documents import from TestRail1,3; Spec2RunAI takes them from Jira, Zephyr, qTest, Excel, or Word. Both integrate with CI (GitHub Actions, Jenkins, and Azure DevOps appear in testRigor’s “Fit Your Workflow” list1 and in our CI guide) and both position themselves against the maintenance cost of Selenium-style suites. If your question is “can non-engineers automate?”, either answers yes.
What the stored test becomes.
testRigor: a test in a documented command language
testRigor’s documentation states its goal as letting you “write your tests in your way of saying it in plain English,” and presents the language as a table of commands with examples: click "Submit", enter "Peter" into "First Name", check that page contains "Hello", select "code or value" from "MySelect". “All references must be in double quotes”; element references can be positioned relative to others (click on button "Delete" below "Actions"); teams save sequences as named Reusable Rules2. The home page describes “translating high-level instructions like purchase a Kindle into a more specific set of steps such as” enter "Kindle" into "Search", press enter, click "Paperwhite", click "Add to cart", and adds: “You always have the ability to correct these instructions and expand upon them using supported commands”1. The stored test is written in those commands, and that is what the team maintains.
Spec2RunAI: the tester’s wording, resolved at run time
Spec2RunAI stores the test case as the tester wrote it — business jargon, multi-action lines, expected results where the tester put them — and resolves each step against the live screen when the test runs. There is no command vocabulary and no translated version of the test to maintain. Proven steps replay from selector memory without a model call. Autonomous Tuning may propose clearer wording for a step that drifted, shown beside the original, and the stored test changes only when a person approves it; the expected result never changes (Assertion Lock). The stored test remains a readable document that could run anywhere a person can read it.
Why this matters more than it sounds: a test written in a tool’s language is maintained in that language, by people who know it, and it leaves with the tool. A test kept in the tester’s words is maintained by the tester, in a document that is also the UAT script, the audit evidence, and the requirement trace. Neither is wrong. They are different answers to who owns the suite.
Facts as each vendor states them.
Left column: vendor statements, not verified by us; superscripts point to the source list. Right column: our statements, with the measurement conditions on the Spec2RunAI page. “Not described” means we did not find it on the pages reviewed, not that it does not exist — ask testRigor.
Where testRigor is the better choice
Native mobile, desktop, API, and mainframe. If your regression spans iOS and Android apps, Windows desktop software, APIs, or a mainframe, testRigor’s site covers all of them from one tool and we do not. SMS and email 2FA. Our secrets vault handles authenticator-app codes; testRigor’s site also lists SMS and email codes1. ISO 27001 and HIPAA. If procurement requires ISO/IEC 27001:2022 or HIPAA, testRigor lists both; we hold SOC 2 Type II. Free start. A free tier lets a team try it without a conversation.
Where Spec2RunAI is the better choice
A manual test library you want to keep as written. If hundreds of UAT scripts already exist and the people who wrote them should keep owning them, there is no translation step and no second language. Sign-off evidence. If a business owner or auditor signs the release, the Run Evidence Report is built for that reader. Insurance and enterprise core systems. Tuned against live Insurity and Guidewire environments. Known cost. Published per-engagement pricing you can model before a call. Your spreadsheets as test data, with no column mapping. Exploration you can bound, with guardrails the engine enforces rather than a prompt suggests. Internal applications through a local agent that never holds an AI key or an authenticator key.
An afternoon’s evaluation, for either tool.
Take ten of your real manual test cases, untouched. Give the same ten to both vendors. Then look at three things: the stored test afterward (is it still your document, or a translated one, and who will edit it?); a run report (how many steps had their expected result verified, and does the report say which did not?); and a deliberate break (rename a button, and read what each tool did and whether the expected result survived). Decide on what you see, not on what either of us says here.
Quick answers.
Is Spec2RunAI a testRigor alternative?
For web application testing from an existing manual test library, yes: both let non-engineers run tests written in English. For native mobile, desktop, API, email, or mainframe testing, no — testRigor covers those surfaces per its site and Spec2RunAI does not.
Does testRigor run existing manual test cases without rewriting them?
testRigor’s site says existing manual cases can be pasted or imported and that high-level steps are translated into its documented commands, which users then correct and expand. Whether that counts as “without rewriting” depends on what you want the stored test to be. Ask to see one of your own test cases after import; that answers it.
Does Spec2RunAI have a command language?
No. There is no documented vocabulary, no required syntax, and no quoting rules. The tester’s wording is the test; the engine resolves it against the live screen. Ambiguous steps are flagged and a clearer wording offered for approval, with the expected result unchanged.
Can Spec2RunAI sign in to accounts protected by two-factor authentication?
Yes, for authenticator-app (TOTP) 2FA, which covers Google Authenticator, Microsoft Authenticator, Authy, and most enterprise setups. The account’s authenticator key is stored once in an encrypted vault and referenced by name in the step; the engine types the current code at run time, waits rather than typing a code about to expire, and never replays a used code. SMS and email codes are not supported. testRigor’s site lists authenticator, SMS, and email.
Which is cheaper?
Spec2RunAI publishes its price; testRigor’s site offers a free start and notes that some capabilities are available only in paid versions, so a like-for-like comparison needs a quote from testRigor. Our three-year cost model takes any per-run or per-seat figure you are given and compares it with an in-house suite in your own numbers.
