End-to-end solution forEnd-to-end testing.

Connect your GitHub repo and Kifas takes it from there. Its agents read your code, figure out which end-to-end tests are worth having, and build them on real browsers and devices. They run on every push. And when one fails, Kifas tells you the thing every other tool leaves you to find out the hard way: whether the test is just stale, or your app is actually broken.

The autonomous loop

Five steps. No babysitting.

Connect a GitHub repository once and Kifas runs the whole testing loop for you, so your engineers can stop maintaining it by hand.

Scan

Kifas reads your codebase: routes, components, API calls, and the user flows they add up to.

Suggest

You get a ranked list of end-to-end tests worth writing, with the critical paths first.

Build

Agents write the tests and run them on Kifas cloud browsers, mobile emulators, and real devices in the Device Farm. No grid to manage.

Run

Tests run on every push. Cold starts land in under three seconds, so coverage keeps pace with your commits.

Self-heal

When a test fails, Kifas compares it against the code change and decides: heal the test, or flag a real bug.

Composable by design

The loop leads. You keep the controls.

The autonomous loop is the fast path, not a cage. Every piece of Kifas is still yours to drive directly.

Read the MCP docs →

→Connect through the MCP server and point Claude Code, Cursor, or Windsurf at any browser, emulator, or real device.
→Run a single flow by hand. Spin up one browser, poke at it, tear it down.
→Take the generated Playwright code and run it in your own CI. It is standard Playwright. No lock-in.
→Mix it up: let the agents own regression while you script the edge cases yourself.

Eight differentiators

What makes Kifas different.

Kifas speaks Model Context Protocol end to end, runs on real browsers, emulators, and physical devices, and tells a stale test from a real bug. Every one of these is a tool your agent can call.

MCP-native, end-to-end

Kifas speaks Model Context Protocol from the first call to the last. 42 MCP tools cover spawning, navigation, assertions, state, and teardown. Your agent talks to Kifas the way it talks to everything else.

Cold starts under three seconds

p50 cold start is under 3 seconds. A browser spawns in about 820ms. Tests that start fast get run more often, which is the whole point.

820ms spawn · <3s p50

Auth Catalog

Logging in is where most E2E suites go to die. The Auth Catalog turns common login flows into one line. Google, GitHub, Okta, email-and-password, magic links: pick the flow, pass your test credentials, move on.

Google · GitHub · Okta · TOTP

Vibe testing

Describe a flow in plain language, like "sign up, add two items, check out with a coupon", and Kifas turns it into a running test. No selector archaeology.

Hybrid engine

First run, the AI explores your app and figures out the flow. Then Kifas compiles it down to deterministic Playwright, so every run after that is fast and repeatable. Exploration when you need it, determinism when you ship.

🔒 deterministic by default

Named, persistent state

Save a logged-in session, a seeded cart, or a configured workspace as a named handle. Reuse it across tests and runs instead of rebuilding state every time.

Self-healing that tells flaky from broken

When a test fails, Kifas does not just retry and hope. It compares the failure against the diff. If a selector moved or a label changed, it heals the test and tells you what it changed. If the behavior actually broke, it stops and flags a real bug. You set how easily a test is allowed to break, so the line between heal it and raise it is yours to draw.

Visual workflow builder

A node-and-edge canvas for the people who would rather see the flow than read it. Branch, loop, and fan out across devices without writing glue code. Non-engineers finally audit coverage.

Kifas vs the usual options

Half the price. The only one that tells flaky from broken.

MCP-first, not MCP-bolted-on

Built MCP-first, not bolted on.

Most tools added an MCP server after the fact. Kifas was built around it. The same 42 tools the autonomous loop uses are the ones you get when you connect your own agent: spawn a device, navigate, assert, save state, tear down. Whatever your agent can reason about, it can now test.
