Optestra vs DIY Claude Code + Playwright MCP
A coding agent driving a browser through Playwright MCP is great for one-off checks; tests need recordings, typed checks, verdicts and a way to run without the agent.
The short answer
Pick a DIY agent setup for a quick look at a page while you code. Pick Optestra if you want the same check on every pull request, deterministic and free to replay.
Start freeWho DIY Claude Code + Playwright MCP is for
Pointing Claude Code (or another coding agent) at Playwright MCP lets the agent open your app, click around and tell you what it saw. It suits quick exploratory checks while you build.
What's different
- An agent session isn't a test: the next run is a new session that may do something else. We record the steps once and replay them exactly, with no model.
- The agent decides whether things 'look right'. We turn each Expect line into a typed check, run by code, that is tested to be able to fail.
- Playwright MCP sends the page's accessibility tree on every action, which can burn a lot of tokens. Our replays use none.
- You can combine both: our MCP server lets Claude Code write tests, run them and read the results.
Feature by feature
About DIY Claude Code + Playwright MCP: from the sources below, checked 9 October 2026. Numbers in brackets point at the source.
| Feature | Optestra | DIY Claude Code + Playwright MCP |
|---|---|---|
| What you get | A test file, a recording and a verdict per run | An agent session; code only if you ask for codegen [1] |
| Repeat runs | Replays the recording with no AI; every check evaluated by code | A new agent session each time [1] |
| Pass or fail | Each Expect line compiled to a typed check, sanity-tested so it can fail; a model never decides the verdict | The agent's judgement, or browser_verify tools [1] |
| Cost per run | $0 AI on replays | Tokens every run; accessibility snapshots can reach 100k+ tokens on a heavy page [2] |
| Secrets | Typed by the harness into their allowed domains only; never shown to the model | --secrets dotenv values redacted from the model [1] |
| Allowed domains | Enforced below the browser: routes, a refusing proxy and a main-frame check | Up to your setup [1] |
| Evidence | Screenshots per step, video with chapters, trace, network log, an HTML report | Session save, video, trace [1] |
| Coding-agent access | MCP server, CLI with JSON output, AGENTS.md instructions | It is the coding agent [1] |
| Price | Engine, CLI and Action free; cloud from $5/month with your own AI key (1,000 credits; $8/month with our AI too, a run of up to 20 tests is 2¢), no seats | Free; you pay your model's tokens [1] |
| Open source | Engine MIT; the app and cloud are closed | Playwright MCP is Apache-2.0 [1] |
When to pick DIY Claude Code + Playwright MCP
- You want a quick look at a page while you code, not a lasting test.
- You're exploring, not checking the same thing on every change.
When to pick Optestra
- You want the same check on every pull request, deterministic and free.
- You want a verdict you can trust without reading an agent's transcript.
- You want your coding agent to write real tests (through our MCP server) instead of improvising each time.
Turn one-off agent checks into tests that replay with no AI.
