## 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

## TestDriver

TestDriver is an AI QA engineer for pull requests. Instead of reviewing code diffs in isolation, it spins up a real desktop sandbox, runs your application, and tests it the way a real user would—clicking, typing and reading the screen. Its vision agent reads the PR diff to understand what changed, generates end-to-end tests from that context, and verifies that the new behavior actually works before it merges.

Because testing is driven by AI vision rather than selectors, TestDriver works on surfaces that break traditional automation: third-party web apps you don't own, Chrome extensions with popups and background pages, native Windows and macOS applications, VS Code extensions, canvas, video players, iFrames and OAuth flows. When the UI shifts and a cached element no longer matches, the agent re-invokes the AI to relocate it, updates the cache and keeps going—so tests self-heal instead of failing on every pixel change.

Generated tests are plain Vitest, so they run identically on your machine and in CI across web, desktop and extensions on real VMs. The agent can also contribute tests back as a new pull request with the code committed for your review. For debugging, TestDriver offers video replays of failing runs, full network inspection with headers and payloads, CPU and memory monitoring, and a step-by-step action log. Pro Cloud pricing starts at $24 per seat per month with 360 testing minutes included, and a free trial is available without a credit card.

**Pricing & Plans:** Free trial (no credit card required) and paid plans. Pro Cloud starts at $24 per seat per month with 360 testing minutes included; enterprise options are available on request.

- **AI code review on every pull request:** TestDriver reviews every pull request automatically, reads the diff with its vision agent, and generates end-to-end tests straight from the PR content to prove the new behavior works.
- **Runs your app in a real desktop sandbox:** Tests run your actual application in a real desktop sandbox—clicking, typing and reading the screen—so they catch runtime and visual bugs, not just code diffs.
- **Self-healing tests:** When the UI shifts and a cached element no longer matches, the AI finds it again, updates the cache and continues, so tests survive redesigns without rewrites.
- **Contributes tests back as a pull request:** Once a test passes, TestDriver opens a fresh pull request with the generated Vitest test code committed, so coverage lands in your repo alongside the change it protects.
- **Debugging and quality monitoring:** Jump from a red build to a video replay of the run, inspect every network request, monitor CPU and memory, and track pass rates, flaky tests and failure trends.

**Strengths:** Runs the real app in a desktop sandbox and catches genuine runtime and visual bugs; No selectors or DOM dependency—tests survive UI changes via self-healing; Covers web, desktop, mobile-style and third-party apps that break other tools; Generates tests and opens pull requests automatically, saving QA hours

**Limitations:** Pricing scales with seats and testing minutes; Focused on GitHub-centric workflows; Running a full desktop sandbox per PR consumes CI time and resources; Advanced enterprise needs may require contacting sales
