6 prices are readable without JavaScript on the pricing page, with no tier routed to sales. Sample prices are $0, $29, $99, $249, and $2,500. All tiers are published and transparent.

1 observation recorded.

Agent-aware instrumentation

Whether you publish anything built for machine callers.

100Strong

MCP manifest published at /.well-known/mcp.json. AI-plugin.json published. Robots.txt names 14 AI crawlers and allows them. OpenAPI spec published. The site declares itself to machines across multiple standards.

4 observations recorded.

Machine-fetchable trust

Whether terms, security and status are readable as text.

85Strong

Security.txt is published with a contact route for machines. The homepage answers automated requests normally. Trust signals are present but limited to security contact and basic availability.

2 observations recorded.

Commercial rails

Whether a purchase can complete without a sales call.

10Blocking

No UCP manifest at /.well-known/ucp. No commerce platform or payment processor detected on the homepage. No published route for an agent to complete a purchase. The storefront is visible to machines but closed to them.

The human door

83 of 100

What a first time visitor meets between landing and first value.

Steps to first value

How far a new visitor travels before something useful happens.

80Strong

Signup form is 2 steps from the homepage. The primary CTA is 'Sign up for free' and leads directly to the form. A human reaches the signup page quickly.

1 observation recorded.

Required fields

How much you ask for before you give anything back.

93Strong

The signup form has 2 fields, both required: Work email and Password. One sign-in option is offered: Google. Both inputs carry validation rules. Friction is minimal.

1 observation recorded.

Verification walls

How many gates stand between intent and access.

80Strong

No verification requirement appears on the signup page itself. Google sign-in avoids email verification entirely. The form does not block entry with a second factor or email confirmation step.

1 observation recorded.

Error recovery

What happens when someone gets it wrong.

80Strong

Both of 2 inputs carry validation rules, so a user sees constraints before submission. No inline error containers or live regions were detected, so recovery feedback after submission cannot be confirmed from this scan.

1 observation recorded.
