## Google Antigravity

Google Antigravity is Google's entry into agentic software development, positioned as a platform rather than a single editor. Instead of asking an assistant to autocomplete a line, Antigravity is designed around agents that take on whole tasks: they read a codebase, produce artifacts such as plans and verification tests, and report back so a human can review the work. The product is distributed across several surfaces so it can fit different workflows — the Antigravity App as a command center for running multiple local agents in parallel, the Antigravity IDE as the fully featured editor with agent manager and artifacts, the Antigravity CLI for keyboard-driven terminal work, extensions for existing editors, and the Antigravity SDK for building custom agents on the same agent harness.

The platform is explicitly aimed at a broad audience: professional developers working in large enterprise codebases, hobbyists vibe-coding on the side, and everyone in between. Google's marketing highlights use cases like frontend and full-stack development, legacy and codebase migrations, technical debt and backlog burndown, automated testing and QA verification, incident triage and root cause analysis, data pipelines and SQL work, developer onboarding and architecture, and enterprise architecture and strategy.

Antigravity connects to Google's Gemini model line, with the site documenting model releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash, plus agent features like voice mode, custom agents, and a plugin marketplace. It is available for macOS, Windows, Linux, and Googlebook, and Google states it is available at no charge for developers.

**Pricing & Plans:** Free to download and use for individual developers according to Google's own site; organization and enterprise plans are offered separately (pricing on request). Model and quota details can change, so check the official pricing page before committing a team.

- **Multiple agent surfaces:** A desktop app, a full agentic IDE, a terminal-first CLI, editor extensions, and an SDK let you run Antigravity agents wherever you already work.
- **Parallel local agents:** Group conversations into Projects and run several local agents at the same time, across multiple workspaces, rather than one at a time.
- **Artifacts and verification:** Agents produce designed artifacts such as plans and comprehensive verification tests so output can be reviewed, not just accepted.
- **Built on Gemini models:** Runs on Google's Gemini model line, including releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash.
- **Agent SDK for custom agents:** Use short Python scripts against the Antigravity harness to prototype custom agents, automate engineering tasks, and run evaluations.

**Strengths:** Free for individual developers and available on macOS, Windows, Linux, and Googlebook; Covers many surfaces — app, IDE, CLI, extensions, SDK — so different workflows are supported; Backed by Google and its Gemini models with a steady release cadence; Verification-oriented: artifacts and tests make agent output easier to review

**Limitations:** Tied to Google's Gemini model line rather than being model-agnostic; Enterprise pricing is not published, so costs require contacting sales; Rapid model and feature changes mean quotas and capabilities can shift

## Prototide

Prototide sits in the browser toolbar and works on whatever page you are already looking at. Instead of switching to a separate review tool or waiting for a teammate's comments, you open the extension, choose whether to review just the current viewport or the whole page, and fill in a short brief: who the page is for, what you want visitors to do there, and which design concerns matter most to you. The extension then produces clear, plain-language observations about hierarchy, clarity, spacing and other visible design issues.

The workflow is deliberately lightweight. Feedback arrives as a list you can read in context, save for later, and work through one item at a time. Because the analysis happens against the rendered page, the suggestions tend to reference concrete elements rather than abstract principles, which makes them easier to hand to a designer or to apply yourself during a quick iteration.

The extension is aimed at solo builders, small product teams and freelancers who want a fast second opinion before shipping. It is free to install, with optional in-app purchases for expanded use. Because the developer's domain no longer resolves and the most recent store update was in mid-2024, treat it as a stable but lightly maintained tool rather than a rapidly evolving platform.

**Pricing & Plans:** Free to install from the Chrome Web Store, with optional in-app purchases for additional features or usage. The listing does not publish specific tier prices, and the developer's pricing page is currently unreachable because prototide.app no longer resolves. Check the in-extension upgrade prompt for current amounts.

- **Screen or full-page review:** Choose a focused critique of the current viewport or a comprehensive pass over the entire page, depending on how broad you want the feedback to be.
- **Brief-driven analysis:** Supply the target audience, the desired action and your own design concerns so the generated feedback is tailored to the page's actual purpose.
- **Actionable in-browser insights:** Read suggestions without leaving the tab, so you can compare each point against the live design and decide what to change.
- **Saving feedback for later:** Keep the review output so you can work through items across multiple sessions or share the list with collaborators.
- **Privacy-conscious data handling:** The developer discloses handling of personally identifiable information and website content, and states that data is not sold to third parties.

**Strengths:** Works directly on any live page in Chrome, with no separate canvas or mockup needed; The audience, goal and concerns brief produces noticeably more relevant feedback than generic checklists; Feedback is saved and readable, making it easy to turn into a task list; Free to install, with upgrades only if you need more usage

**Limitations:** The developer's own site, prototide.app, no longer resolves, so support and documentation options are limited; No store ratings yet and a small install base, so there is limited community evidence about output quality; Updates have been infrequent, with the last published version dating to 2024
