The Radius landing page includes a detailed product screenshot showing an agent session editing files, with the visible status **“Edited 3 files +15 -5”** and passing tests. The report compares this trust signal with other products:

| Conductor | “feels like going from typing with two fingers to having eight arms” — Frank, Product Designer, Thinking Machines. |
| Terragon | No visible trust signal identified. |
| Sculptor (Imbue) | No visible trust signal identified. |
| Cursor | Detailed “Cursor Desktop” product UI showing the “Plan Mission Control” agent workflow and Cursor CLI output. |
| Devin | Embedded Devin session demo showing the task “Migrate all gradient text to #317CFF in both repos, then test” with real project activity. |

## Mobile web — 74, Fair

This category evaluates whether the phone experience is treated as a first-class experience.

![Mobile web annotations on the Radius capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/radiusbrowser.com-mobile.jpg?v=2026-09-22T23%3A56%3A39.87%2B00%3A00)

The mobile review identifies three issues:

1. **Clipped app screenshot:** The desktop IDE capture runs off the right edge, truncating chat text and diff counts mid-word.
2. **Download for macOS button:** A desktop-proportioned pill floats in the column instead of being a full-bleed, thumb-friendly tap target.
3. **Tiny terminal text:** Terminal output in the screenshot renders at a squint-small size and is unreadable on a phone.

## CTA — 78, Fair

This category evaluates the primary call to action by its copy, size, verb, and perceived cost.

![Radius CTA comparison](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/radiusbrowser.com.jpg?v=2026-09-22T23%3A56%3A39.87%2B00%3A00)

Radius’s primary CTA is **“Download for macOS.”** The report identifies these problems:

- The download feels heavy, with no de-risking.
- The label provides no value payoff.
- macOS-only availability excludes other visitors.

## Information hierarchy — 82, Strong

This category evaluates whether the design helps or inhibits the page’s message.

![Information hierarchy annotations on the Radius desktop capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/radiusbrowser.com.jpg?v=2026-09-22T23%3A56%3A39.87%2B00%3A00)

The review identifies three hierarchy issues:

1. **Duplicate nav Download button:** The outlined navigation Download button competes at near-equal weight with the hero **“Download for macOS”** CTA.
2. **Three navigation exit links:** Docs, Changelog, and Community appear above the CTA and draw attention away before the download action.
3. **Cropped product screenshot:** The agent-session screenshot is cut mid-fold, so its diff and terminal payoff does not fully land on desktop.

## Value props — 82, Strong

The review evaluates whether the title, subtitle, and hero sell Radius’s true value.

### Headline and positioning

> **Your browser should be your IDE.**

> Radius is a browser where you can run coding agents in parallel, right next to your PRs, docs, terminals, and localhost servers.

### What works

- Bold, concrete category claim.
- Subhead lists real development nouns.
- Hero shows an agent fixing a real issue.

### What could improve

- No numbers or measurable outcome.
- Emotionally flat; no pain is named.
- The payoff of running parallel agents is left implicit.

### Value-proposition ranking

1. Radius — 82
2. [Conductor — 78](https://www.lazyweb.com/growth-score/site/conductor.build)
3. [Cursor — 76](https://www.lazyweb.com/growth-score/site/cursor.com)
4. [Devin — 76](https://www.lazyweb.com/growth-score/site/devin.ai)
5. [Sculptor (Imbue) — 52](https://www.lazyweb.com/growth-score/site/imbue.com)
6. [Terragon — 45](https://www.lazyweb.com/growth-score/site/terragonlabs.com)
