# Seldon

> Seldon deploys QA agents that explore your app to find bugs by trying different user paths toward a given goal. It is for engineering and QA teams who want to catch issues that scripted tests miss.

### About Seldon

Seldon is an applied research lab that built Wren, a behavioral QA agent. Wren tests software by simulating how customers actually use a product, exploring different paths rather than following a single scripted route. When the agent encounters a bug, it generates a recording and lists the steps needed to reproduce the issue.

### Review

Seldon's Wren addresses a specific gap in automated testing: a test suite can pass every assertion while a customer still hits a bug minutes after deployment. The tool uses plain English goals to guide its agents, which then interact with an application and try variations real users might attempt. The first 10 runs are free, and the team has indicated it can operate alongside existing CI test suites.

#### Key Features

- Accepts testing goals written in plain English, such as "a new teammate should be able to accept an invite and join the workspace."
- QA agents explore multiple paths toward a goal, including switching accounts mid-flow or retrying a failed action, without requiring separate scripts for each variation.
- Produces a recording and reproduction steps when a failure is detected, so teams can review what the agent did.
- Models agent behavior on observed user behavior patterns rather than random clicking, according to the makers.
- Integrates into existing CI pipelines and can run on staging environments with test accounts.

#### Pricing and Value

Seldon offers 10 free runs to start. Beyond that, pricing details are not yet defined on the product page. The team positions Wren for both startups shipping weekly and enterprise teams with extensive test coverage. One early user reported that Wren saved days of QA effort before a release, though this claim hasn't been independently verified.

#### Pros

- Tests paths that scripted suites often miss, such as interrupted checkouts or account-switching during onboarding.
- Setup doesn't require documentation; you point Wren at an app and describe a customer action.
- Agents adapt to unexpected popups and loading delays, then report where they got stuck and how they attempted to recover.
- Cleanup steps can be added directly into the plain English test instructions.
- Recordings let teams verify whether a flagged issue represents a genuine user-facing problem.

#### Cons

- Wren is web-only at launch. Native app testing is on the roadmap but not available yet.
- There is no automatic cleanup after a run; users must write cleanup steps or point the agent at a throwaway account.
- Teams that need hard guarantees against certain actions (like submitting a real financial transaction) cannot rely on a plain English instruction alone to block it. A staging environment with test-only funds is the recommended workaround.

Wren fits engineering and QA teams that already have passing test suites but want to surface the edge cases scripted tests overlook. It's less suited for native mobile teams who need a solution today, since native support is still in development. For web applications where user paths branch unpredictably, the tool's approach of working toward a goal rather than following rigid steps may catch failures that would otherwise surface only in production.
