What is Keploy?
Keploy supports developers by creating tests from real calls or an API specification. It simulates services and databases, replays tests in development pipelines, and detects regressions.
According to its documentation, Keploy lets you:
- create tests from real calls
- generate tests from an API specification
- simulate services and databases
- replay tests in development pipelines
- detect regressions
We file it under Developer tools, the category of tools to test, document and ship software, and it also overlaps with aI coding assistants. The category lists 31 verified tools on this site.
The publisher is Keploy, Inc., based in United States. The service launched in 2022, which gives it some track record.
Who is it for?
It is mostly useful to these profiles: developers. The need it covers is simple to state: test, document and ship software.
Keploy is a good candidate if:
- you want to try before paying
- you plan to connect it to your tools or automations through its API
- you want to read the code or host it yourself
The best test is a concrete case from your daily work: if the tool does not beat your current method within a week, move on to an alternative.
How much does Keploy cost?
Pricing model: open source (public code). A free plan is offered, usually limited in volume or features.
The first paid plan costs $19 per month (Pro, per user, with USD 19 in usage credit; additional consumption is billed), according to the pricing page, checked on October 24, 2026.
Per month, that is close to the category median ($16.99 per month, based on tools with a published price).
To estimate what the same work would cost done directly with an AI model, use our API price calculator. Prices change often: always check the official site before subscribing.
Data and privacy
The publisher does not clearly state where data is hosted. Assume your content may leave your region.
For professional use, check that a data processing agreement (DPA) is offered, and do not send customers' personal data or confidential documents without one.
Exporting your content: yes (details on the official site). Being able to get your data back makes switching tools easier later.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
Platforms, languages and API
Keploy runs on: web browser, Windows, macOS, Linux, browser extension, and API.
Interface languages are not specified.
A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
The source code is public: keploykeploy/keploy.
