The facts, with their sources

What it does

Writes code: YesStudio'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.Katalon Studio AI agents generate scripts from natural language, explain scripts and fix failureskatalon.com/pricing
Debugs and fixes: PartlyIt diagnoses failing tests and repairs them: self-healing retries alternative locators and the Root Cause Analyzer recommends fixes, but the vendor frames the fix as a test change you review rather than a patch to application code.Self-healing keeps tests running, and failure analysis pinpoints the root cause. Katalon AI fixes the test and you review it.katalon.com
Writes tests: YesProducing tests is the product: the Test Case Generator writes cases from a requirement, ticket or prompt, and the Requirement Analyzer plans coverage before the cases are generated.Generates the minimum set of tests needed to cover a requirement - then prompts you to expand with edge cases, negative scenarios, or automated test…katalon.com/ai-powered-testing-platform
Whole-codebase work: PartlyThe documented migrations are across a test suite rather than an application repository: the vendor's own MCP prompts convert whole login suites to Playwright and it publishes a Selenium migration path, with no claim about repo-wide application refactors.convert the login suite to Playwright with Page Object Modelkatalon.com/katalon-mcp
Done-for-you service: NoYou 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.Seat (Katalon Studio, TestOps): one seat is one named user. Buy a seat for each person who authors, manages or reports on tests.katalon.com/pricing

How much it does unattended

Runs autonomously: YesThe 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.Takes manual test cases written in Natural Language and executes them autonomously with no test automation involved.katalon.com/ai-powered-testing-platform
Multi-agent: PartlyKatalon 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.Natural-language interface that translates intent into orchestrated, end-to-end workflows.katalon.com/ai-powered-testing-platform
Agent permissions: PartlyGenerated tests are produced for human review and approval before use, and administrators can switch AI off per project or organisation-wide, so the agent's reach is bounded by configuration rather than open-ended.Administrators can disable AI per project or across the organization.katalon.com/security

Which models it runs on

Claude: PartlyClaude 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.Use the built-in Katalon AI Service, no key needed, or connect your own provider.katalon.com
GPT: YesGPT is the model behind the built-in service on every plan: Katalon states AI input is processed through OpenAI's GPT models, and OpenAI or Azure OpenAI can also be connected as your own provider.AI data input is processed through OpenAI’s GPT models. This data is securely transmitted and processed by OpenAI.katalon.com/ai-powered-testing-platform
Gemini: PartlyGoogle 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.Bring your own AI providerkatalon.com/pricing
Model choice: PartlyYou can route AI to your own provider keys instead of Katalon's service, but on the Studio plan ladder that control is Enterprise-only; the True Platform bundles list 'Configure AI services' as included.katalon.com/pricing

Where you use it

In your editor: YesKatalon Studio is itself a desktop authoring IDE, and the MCP server additionally drives the platform from Cursor, VS Code, Windsurf, Zed, JetBrains and other editors.Katalon Studio seats include advanced test automation, full features in Katalon Studio - the IDE desktop app.katalon.com/pricing
On the command line: YesRuntime Engine licences run Studio tests headless from the command line, and the remote MCP server is installed with a terminal command for CLI agents such as Claude Code and Codex.Katalon Runtime Engine licenses run Studio tests headless in CI/CD. Extends Katalon Studio plans.katalon.com/pricing
In your pipeline: PartlyCI/CD execution in Jenkins, GitHub Actions, Azure DevOps and GitLab is listed as included from Professional upward, but the vendor states it needs the separately purchased Katalon Runtime Engine add-on.CI/CD: Jenkins, GitHub Actions, Azure DevOps, GitLabRequires Katalon Runtime Engine add-onkatalon.com/pricing
In a browser: YesTestOps is a hosted web application for test management, run evidence and analytics, and TestCloud runs browsers and real devices from the same cloud platform.TestOps manages cases, runs and release evidence, Studio authors web, mobile, API and desktop tests, TestCloud runs them in parallel on real browsers…katalon.com

Whose machine it runs on

Self-hosted: PartlyExecution can run entirely on your own machines, Docker or CI, and private-cloud or on-premises deployment of the platform is an Enterprise-only, agreement-based option rather than something any plan can switch on.katalon.com/pricing
Open-source runtime: PartlyThe standing Free plan authors and runs tests locally on your own machine with no paid subscription, but it is reached through a Katalon sign-up rather than a vendor-account-free download, and it omits AI, CI and cloud execution.Author and run tests locallykatalon.com/pricing
Runs in your cloud: PartlyTest execution and its data can stay inside your own infrastructure under the customer-controlled model, and dedicated or region-specific cloud environments exist by agreement, with the vendor warning some SaaS features still need connectivity.Test execution and associated data remain in the customer-controlled environmentkatalon.com/security

Building with it

Tracing and evals: YesTestOps is the system of record for every run: flakiness detection, AI root-cause analysis, traceability and coverage reports, custom dashboards and exportable evidence across manual, Katalon and Playwright executions.Requirements, test cases, evidence, defects, releases: one auditable record for reporting application quality, not spreadsheets.katalon.com

What it costs to run

How it meters: YesPricing is per named seat for Studio and TestOps, per concurrent session for TestCloud and per concurrent licence for Runtime Engine, with the vendor explicitly ruling out per-run or usage charges.No per-run or usage fees. Katalon prices by seats and sessions, not by how much you run.katalon.com/pricing
Cost of one job: YesOne automation engineer on the cheapest paid path costs $1,000 a year self-serve for the first three seats, about $84 per seat per month, then $1,800 per seat, with unlimited runs and unlimited AI sessions inside that seat.Katalon Studio - $1,000/seat for the first 3 seats, then $1,800/seat, billed annuallykatalon.com/pricing
Free tier: YesSigning up starts a 30-day trial with no credit card, and when it ends the account drops to a standing Free plan that keeps local authoring and execution rather than locking you out.No credit card needed. Every new sign-up starts a 30-day trial.katalon.com/pricing
API access: YesKatalon publishes two REST API suites on its developer site, a TestOps API for results, schedules and reports and a TestCloud API for cloud execution, with documented authentication, errors and rate limits.TestOps API: Enables integration with Katalon TestOps to manage test results, schedules, and reports programmatically.developers.katalon.com/reference/api-re…
MCP server: YesTwo MCP servers exist, a remote OAuth one for True Platform and a local one shipped inside Studio, and the pricing table lists MCP as included from Professional upward but not on the Free plan.Connect the True Platform MCP (remote, OAuth) or the Katalon Studio MCP (local, ships inside Studio) to the agent your team already uses.katalon.com/katalon-mcp
Bring your own key: PartlyOrganisation-provided provider keys can carry supported AI requests instead of Katalon's own service, but the Studio plan table puts bring-your-own provider on Enterprise only, so entry buyers use Katalon's inference.Authorized admins can enable or disable AI features, and supported AI requests can be routed through organization-provided provider keys.katalon.com

Buying it for a team

A company can buy it: YesTeams buy online as three-seat True Manual or True Automation bundles or as individual Studio and TestOps seats, with an Enterprise annual contract for larger organisations needing deployment and compliance terms.Annual contract, tailored to your seats, deployment and compliance needskatalon.com/pricing
Seat model: YesSeats are named users and reassignable at any time; there is a floor of three seats on the True Platform bundles, and Studio's online price steps from $1,000 to $1,800 per seat after the first three.A seat can be reassigned to another user at any time.katalon.com/pricing
Pooled budget: PartlyAuthoring capacity is per named seat, while execution capacity is pooled: a TestCloud session is one concurrent slot the whole organisation queues against, and bundles grant one free cross-browser session per five seats.Session (TestCloud): one session is one concurrent slot for its specific session type, such as Cross-Browser or Live Testing.katalon.com/pricing
Admin controls: YesAdministrators hold role-based access control, project-scoped roles, licence allocation and the switch that enables, restricts or disables AI features per project or across the organisation.Organizations can enable, restrict, or disable AI features based on their governance, deployment, and compliance requirements.katalon.com/security
Audit log: YesAudit logs and compliance controls are listed as included on both True Platform bundles and mapped to ISO 27001 A.8.15 on the security page; on the Studio-only ladder they are an Enterprise capability.Audit logs & compliance controlskatalon.com/pricing
Single sign-on: YesSAML 2.0 and OpenID Connect are both supported, configured per organisation, with SCIM 2.0 provisioning alongside; on Studio-only plans SSO sits in the Enterprise column.SAML 2.0 and OpenID Connect (OIDC), configured per organizationkatalon.com/security

What happens to your code

Opt out of training: YesThere is nothing to opt out of: Katalon states customer data, prompts and artifacts are never used to train AI models and that it holds zero-data-retention agreements with its managed model providers.Customer data, prompts, and artifacts are not used to train AI models.katalon.com/security
Data residency: PartlyRegional hosting is offered in the United States and Europe, and region-specific or customer-controlled environments by agreement, but Katalon qualifies that availability depends on the product and deployment model.Regional hosting options are available in the United States and Europe; availability depends on the product and deployment model.katalon.com/security
Getting out: YesRun history, approvals and defect links are exportable for audit, reports can be exported and shared on every plan including Free, and because billing is by seat and session there are no credits to expire.Exportable run history, approvals, and defect links help internal audit and regulatory teams review the evidence behind each release.katalon.com/security
Certifications: YesKatalon publishes ISO/IEC 27001, 27017 and 42001 certifications, a SOC 2 Type II attestation and a GDPR processor DPA, with certificates and pentest summaries requestable through its Trust Center.ISO/IEC 27001Certified ISO/IEC 27017Certified ISO/IEC 42001Certified · AI management SOC 2 Type IIAttestation GDPRProcessor · DPA availablekatalon.com/security
