Multi-context testing

Test complete journeys across users, tabs, and inboxes

Protect collaboration, approval, invitation, and verification flows in one run while each user keeps an isolated session.

Create your first test

Start for free • No credit card required

Single-session scripts miss the moments where collaborative products often fail. Mechasm guides one test across isolated browser contexts and inbox actions so your team can verify the complete journey without splitting it into disconnected scripts.

A clear path forward

Move from testing friction to release confidence

Create each user context

Give every participant an isolated browser session with its own cookies, storage, and cache.

Move through the shared journey

Switch between users, tabs, and email steps without losing the state of the original flow.

Inspect every perspective

Use separate videos and trace views to understand what happened for each user.

Protect workflows that cross users and channels

Keep connected workflows together when actions span roles, sessions, and inboxes.

Real-time collaboration

Verify that actions from one user become visible for another user in the same run.

Role-based approvals

Switch between standard-user and admin sessions to validate request and approval flows.

Email-assisted onboarding

Continue invite, reset, and verification journeys using links or codes delivered during the test.

Keep complex journeys understandable

Run realistic collaboration scenarios while preserving clear evidence for every participant.

Session isolation

Each context keeps its own cookies, local storage, session storage, and cache so users stay isolated.

Flexible email link handling

Open a reset or invite link in the current page, a new tab, or a separate isolated context depending on the workflow.

Per-context debugging assets

Videos and trace views stay separated by session so it is easier to understand what happened for each user.

Your three-step plan

Prove it on your own workflow

Start free, use one real user journey, and decide from evidence generated against your application.

Create your first test
  1. 1. Describe a real journeyWrite the acceptance path in plain language.
  2. 2. Run it on your applicationUse the same environment and interactions your users depend on.
  3. 3. Review the evidenceInspect the run, decide what to keep, and export when you want code ownership.

Build the workflow your team needs

Add the capabilities that help your team create, run, debug, and maintain reliable tests with less friction.
