## Shortlist

### 1. Applitools

Visual AI and no-code end-to-end testing platform for web, mobile and AI-generated UI.

**Where it improves on Testsigma:**
- [Agent permissions: yes — The MCP server enforces what a connected agent may settle: review gates on the server side require verified visual evidence before a test or baseline can be resolved.](https://applitools.com/solutions/agentic-testing/)
- [Claude: yes — Claude Code is named as a natively supported agent environment for the Eyes MCP server, set up through standard MCP client configuration.](https://applitools.com/solutions/agentic-testing/)
- [Tracing and evals: yes — Each run is inspectable: automated maintenance and root-cause analysis ship on Starter, and REST endpoints return batch results and statistics for programmatic reporting.](https://applitools.com/docs/eyes/reference/server-api)

**Trade-offs against Testsigma:**
- [GPT: partial — GitHub Copilot is listed as a supported agent environment, which implies OpenAI models in the loop, but no page states that GPT models themselves can be selected or configured.](https://applitools.com/solutions/agentic-testing/)
- [Model choice: no — The checking engine is the vendor's own: a proprietary Deterministic Language Model plus Visual AI trained in-house, so the buyer does not choose the model that does the validation.](https://applitools.com/)
- [Bring your own key: partial — You can bring your own infrastructure, running Applitools in a dedicated cloud on AWS, Azure or GCP, but the pricing page gates private cloud as a Professional add-on and includes it only on Enterprise.](https://applitools.com/platform-pricing/)

### 2. Functionize Studio

Agentic end-to-end test platform that builds, runs and repairs tests against your live web app.

**Where it improves on Testsigma:**
- [Runs autonomously: yes — A single prompt produces a built, executed and self-maintained test, including re-runs on failure and fixes applied without a person in the step.](https://www.functionize.com/agent-tasks)
- [Agent permissions: yes — You set how far the agent may go and every edited step writes a restore point you can inspect or roll back with one click, so changes are reversible.](https://www.functionize.com/architecture)
- [Tracing and evals: yes — Every run is recorded with pass/fail, browser and duration, each step screenshotted, each element match shown with its bounding box, and reports export to CSV.](https://www.functionize.com/agent-tasks)

**Trade-offs against Testsigma:**
- [Ships it: no — It stops at proving the change: suites, reports and fixes come back, while the release decision is explicitly left with the buyer rather than automated.](https://www.functionize.com/agent-tasks)
- [Done-for-you service: no — This is software the buyer runs themselves: sign-up is self-serve, there is nothing to stand up, and no engagement where Functionize staff build or operate suites for you.](https://www.functionize.com/architecture)
- [GPT: no — The vendor answers the wrapper question directly: the element model and data layer are in-house and no third-party model endpoint sits under a result.](https://www.functionize.com/architecture)

### 3. Katalon

AI testing platform with authoring, test management, cloud execution and an MCP server for coding agents.

**Where it improves on Testsigma:**
- [Writes code: yes — Studio's AI agents generate automation scripts from natural language and from Jira or Azure DevOps tickets, and the API Generator builds API tests from OpenAPI specs; generated output is meant for human review.](https://katalon.com/pricing)
- [Runs autonomously: yes — The Autonomous Test Runner executes natural-language manual test cases end to end with no automation script and no human stepping through them, while the vendor keeps humans accountable for the release decision.](https://katalon.com/ai-powered-testing-platform)
- [Claude: partial — Claude is reachable only by pointing Katalon at your own AWS Bedrock provider, and bringing your own AI provider is an Enterprise capability on the Studio plan ladder rather than something the built-in service offers.](https://katalon.com/)

**Trade-offs against Testsigma:**
- [Done-for-you service: no — You buy and run licensed software: Katalon sells named seats, TestCloud sessions and Runtime Engine licences, with people-delivered work limited to Enterprise onboarding and enablement rather than running testing for you.](https://katalon.com/pricing)
- [Multi-agent: partial — Katalon publishes a dozen specialised agents (requirement analyser, generator, runner, root cause analyser) and an assistant that orchestrates end-to-end workflows, but no page describes several agents coordinating on one task as a user-configurable orchestration.](https://katalon.com/ai-powered-testing-platform)
- [Gemini: partial — Google Gemini appears only as a provider you can connect yourself, and that bring-your-own-provider control sits on Studio Enterprise rather than the Free or Professional plans.](https://katalon.com/pricing)

### 4. mabl

Agentic testing platform whose agents author, run, recover and triage tests for web, mobile and APIs.

**Where it improves on Testsigma:**
- [Writes code: yes — mabl authors runnable tests from plain-language intent, a user story or pasted Jira acceptance criteria; it generates test logic, not application source code.](https://www.mabl.com/active-coverage)
- [Runs autonomously: yes — Agents generate, run on a schedule, investigate failures and heal tests without a person in the loop, though the vendor says recovery updates can be held for human approval.](https://www.mabl.com/active-coverage)
- [Agent permissions: yes — Autonomy during test recovery is a setting with three documented levels, so a team decides whether a healed step may change a run's outcome; every agent action is logged for review.](https://www.mabl.com/active-coverage)

**Trade-offs against Testsigma:**
- [Done-for-you service: no — You run the software yourself; mabl's people provide onboarding, a Customer Success Manager and an optional Technical Account Manager who advise on adoption rather than build and operate your test suite.](https://www.mabl.com/pricing)
- [Licence: no — proprietary: the terms of service grant a non-exclusive, non-transferable right to use the hosted service for internal business operations only, so a company cannot redistribute or ship it.](https://www.mabl.com/tos)
- [Opt out of training: no — The terms of service take an irrevocable, perpetual licence over aggregated data derived from your use of the service for mabl's business purposes, including improving it, and no opt-out is published.](https://www.mabl.com/tos)

### 5. testRigor

Generative-AI test automation driven by plain-English test steps for web, mobile, desktop, API and mainframe.

**Where it improves on Testsigma:**
- [Runs autonomously: yes — Branch validation is designed to run with nobody in the loop: it connects repository and specification, deploys, checks the behaviour and reports, explicitly so engineers need not wait for a QA or product-manager pass.](https://testrigor.com/autonomous-branch-validation/)
- [Claude: yes — Claude is supported as the agent that drives testRigor, through its MCP server and published skills; the vendor does not say which model powers testRigor's own AI inside the platform.](https://testrigor.com/)
- [Tracing and evals: yes — Each run is inspectable step by step through the MCP tools and the web app, with failures listed separately, video recordings of executions and JUnit XML written out for CI dashboards.](https://testrigor.com/how-to-utilise-testrigors-mcp-server/)

**Trade-offs against Testsigma:**
- [Done-for-you service: no — You run software rather than hire a team: the vendor hosts the execution infrastructure and the buyer writes and maintains the tests, with the people on offer being support and customer success, not a build service.](https://testrigor.com/faq/)
- [Open-source runtime: no — Even the open-source skills route requires a vendor account: the setup section states you need a testRigor account for an API token before the CLI or MCP server will do anything.](https://testrigor.com/write-run-maintain-testrigor-tests-with-claude-code/)
- [Admin controls: partial — User access management is a real feature but the plan comparison ticks it in the Enterprise column alone, so neither the free plan nor Private Complete gets administrative control over who may do what.](https://testrigor.com/sign-up/)

### 6. Testim

AI-driven UI and end-to-end test automation for web, mobile and Salesforce apps.

**Where it improves on Testsigma:**
- [Writes code: yes — Generative AI turns a text description into custom test code, so testers get code steps without writing them by hand.](https://www.testim.io/ai/)
- [Debugs and fixes: yes — It diagnoses broken runs with logs, HAR files and screenshot comparison, and its AI locators repair the test itself when the app changes.](https://www.testim.io/)
- [Runs autonomously: yes — The vendor claims its collaborating agents produce working tests with no human step in the middle of the build.](https://www.testim.io/ai/)

**Trade-offs against Testsigma:**
- [Open-source runtime: no — Even local runs need a project ID and an access token issued inside the hosted app, so there is no vendor-account-free way to run it.](https://docs.tricentis.com/testim/content/running-tests/the-command-line-cli/index.htm)
- [API access: partial — A REST API covers branches, tests, runs and executions, but the documentation gates it to projects on the professional plan.](https://docs.tricentis.com/testim/content/administration/api-access.htm)
- [Admin controls: partial — Owners control project settings, membership and credential access, and read-only accounts exist but only stop saving tests in the UI.](https://docs.tricentis.com/testim/content/administration/project-and-user-management.htm)
