Katalon Studio

Katalon Studio is a test automation IDE for creating and running tests across web, mobile, API, and desktop applications. A shared project supports no-code, low-code, full-code, and AI-assisted authoring. The web recorder creates reusable Selenium-based tests, while the mobile recorder captures interactions for Appium-based flows. API testing covers REST, SOAP, and GraphQL alongside UI tests. Katalon AI can generate tests, analyze failures, and repair locators, and administrators can enable or disable those AI features. Listed integrations include Jira, Azure DevOps, Jenkins, GitHub Actions, GitLab, Slack, Bitbucket, and Azure Repos. Downloads are available for Windows 64-bit, macOS Intel, macOS Apple Silicon, and Linux. The Free plan allows local authoring and execution, recording and playback, and up to 40 static test suites, but does not include AI or parallel execution. Professional costs $1,000 a year, billed annually, for the first three seats. The full Enterprise version has a 30-day trial with no credit card required.

Katalon Studio combines UI and API testing with several authoring options and recorders. The Free plan has defined feature limits, while Professional pricing is listed annually for the first three seats.

It suits teams that need to author and execute tests across web, mobile, API, and desktop applications. The mix of authoring modes and integrations may fit teams with different testing workflows.

Overview

Katalon Studio is an IDE for building and running automated tests across web, mobile, API and desktop applications. It suits teams that want both technical and less technical contributors working in one project, with room to combine recorded flows, code and AI assistance. Its broad coverage is compelling, but the Free plan’s 40-suite ceiling and lack of parallel execution limit its usefulness as test volume grows.

Key features

Authors can work with no-code, low-code, full-code or AI-assisted methods in a shared project. That range can accommodate mixed-skill teams without splitting their work across separate tools; teams looking for a narrowly focused recorder may find the IDE’s wider scope unnecessary.

The web recorder creates reusable Selenium-based tests, while the mobile recorder captures Appium-based flows. API testing covers REST, SOAP and GraphQL in the same project as UI tests. This breadth is useful when teams want related checks in one workflow, and cross-browser support, mobile web testing and visual testing extend the coverage.

Katalon AI can generate tests, analyze failures and repair locators, and administrators can disable AI features. Katalon says it does not use customer prompts, test artifacts or generated outputs to train its own or third-party models. Customer data is encrypted at rest with AES-256 and in transit with TLS 1.2 or higher. Katalon lists ISO/IEC 27001, ISO/IEC 27017 and ISO/IEC 42001 certifications, SOC 2 Type II attestation and GDPR processor status.

Integrations include Jira, Azure DevOps, Jenkins, GitHub Actions, GitLab, Slack, GitHub, Bitbucket and Azure Repos. Studio builds are offered for Windows 64-bit, macOS Intel, macOS Apple Silicon and Linux; self-hosted runners are supported.

Pricing

The Free plan costs nothing. It includes local authoring and execution, record and playback, and up to 40 static test suites. The cap and the exclusion of parallel execution and AI script generation make it a sensible way to start small, but a poor fit for teams that need concurrent runs or expect their suite collection to expand.

Professional costs $1,000 a year, billed annually, with the offer applying to the first 3 seats. It includes AI agents, web, mobile, API and desktop testing, unlimited and dynamic test suites, parallel execution and integrations. The paid tier addresses the Free plan’s most consequential limits, though buyers should account for the annual term and the stated first-three-seat offer when evaluating team costs.

Katalon Studio Enterprise is offered as a 30-day trial of the full version, with no credit card required. Its feature set includes low-code and full-code authoring, AI Assistant and MCP Server, web, mobile and desktop recording, local execution and reports, plus AI self-healing and failure analysis. The price is custom pricing.

Enterprise also has an annual contract, with custom seats, deployment and compliance, SSO/SAML and SCIM, role-based access controls and audit logs, private cloud or on-premises deployment, and premium support with an SLA. It is aimed at organizations that need administrative controls, deployment choice or contractual support rather than simply more test capacity. Professional includes a 24/5 ticket system; Enterprise’s SLA-backed premium support is the higher-support option.

Platforms

Katalon lists Android, iOS, Linux, macOS, self-hosted, web and Windows platforms. The desktop downloads cover Windows 64-bit, Intel and Apple Silicon Macs, and Linux. That spread supports teams working across desktop environments and mobile targets, while self-hosted execution offers an alternative to relying only on local workstations.

Who it's for

Katalon Studio is strongest for teams that need web, mobile, API and desktop test automation together and want contributors with different coding skills to share a project. It is also a fit for organizations that value AI-assisted authoring, integrations and the option of self-hosted, private-cloud or on-premises deployment. Solo users or small teams with modest suites can begin free; teams requiring parallel runs, more than 40 static suites or AI script generation will need to consider Professional or Enterprise.

Pros and cons

• Pro: No-code through full-code and AI-assisted authoring share one project, so contributors can use different approaches without splitting test work.
• Pro: Selenium-based web recording, Appium-based mobile recording and REST, SOAP and GraphQL coverage bring several application layers into one IDE.
• Pro: Professional removes the Free plan’s suite cap and adds parallel execution, with AI agents and integrations included.
• Pro: Enterprise deployment options, identity controls and SLA-backed support suit organizations with more demanding operational requirements.
• Con: Free is capped at 40 static suites and excludes parallel execution and AI script generation, so it can become restrictive as a test program scales.
• Con: Professional is billed annually, and its stated price offer applies to the first 3 seats, which matters when comparing costs across a larger team.
• Con: Enterprise uses custom pricing and an annual contract, making it a less direct fit for buyers who need a simple, published per-seat cost.

Alternatives

TestCafe is a better fit for readers seeking a free, open-source test runner under the MIT license rather than Katalon’s paid tiers and broader IDE workflow.

Testim is worth considering for organizations that want a free Community plan, which is limited to one plan per organization and documentation and Community Slack support.

TestMu AI Web Automation (formerly LambdaTest Web Automation) may suit teams looking for a freemium option with a free tier that includes 100 lifetime minutes and two parallel web and mobile automation sessions.

Tricentis Testim is an alternative for teams whose needs fit its free allowance of up to 1,000 runs per month or its customized paid plans for mobile and web testing.

Detox is an open-source framework under the MIT License.

Maestro offers a free, open-source local option for running on your own devices, with local agents and Maestro MCP, Viewer, Studio and CLI.

Nightwatch is an open-source option with no paywalls and all features available to everyone.

WebdriverIO is a free, open-source automation framework that requires Node.js.

Verdict

Choose Katalon Studio if your team needs one shared environment for UI, mobile, API and desktop automation, especially when authors have different coding skills or you need AI assistance and flexible deployment. Its strongest reason to choose it is the combination of broad test coverage and multiple authoring paths; its clearest drawback is that the useful scale-up features come with an annual Professional commitment or custom-priced Enterprise terms. For a small suite, Free is a credible starting point, but teams needing parallel execution should look beyond it.
