## 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

## ModelBound

ModelBound treats agent skills the way engineering teams treat code: something that should be measured, reviewed and tested rather than written once and forgotten. Running a single scan command profiles every rule and skill in a repository, reporting how many tokens each one loads on every turn, where loops risk never terminating, and which skills contain unscoped or destructive shell commands.

Instead of stopping at static analysis, ModelBound connects to real runs. Plugins for Claude Code and Cursor, a VS Code extension, a CLI for terminals and pipelines, and an MCP server with 45+ tools all stream summaries back to the profiler. You can see failure rates, repeated tool calls and silent regressions tied to specific skill versions, and enforce a check in CI so a regression blocks a merge.

The privacy stance is deliberate: profiling works locally and the homepage states that nothing leaves your machine, with summaries rather than prompts being transmitted. Every plugin, the CLI and the MCP server are open source, which suits teams that want to inspect the tooling running against their repositories before adopting it.

**Pricing & Plans:** Freemium with a free entry point: the npx modelbound scan command profiles rules and skills in your repo without an account. Identified as freemium, free trial and free tiers; the pricing page renders client-side, so check modelbound.co/pricing for current plan limits and paid seats before budgeting.

- **Token and context profiling:** See how much context each skill file loads on every turn, plus token usage from recorded runs, so bloated skills are visible before they slow agents down.
- **Failure and loop detection:** Track failed runs and repeated tool calls per skill, and flag loop risks where a skill has no stop condition.
- **Safety findings:** Static checks surface unscoped or destructive shell commands, such as rm -rf, and other risky patterns in skill files.
- **Editor, CLI and CI integration:** Plugins for Claude Code and Cursor, a VS Code extension, a terminal CLI and an mb check step for pipelines bring profiling into existing workflows.
- **Open source and MCP server:** The plugins, CLI and a 45+ tool MCP server are public on GitHub and support local-first or hosted operation.

**Strengths:** Local-first design keeps prompts and code on your machine; Works directly inside Cursor, Claude Code, VS Code, the terminal and CI; Combines static risk findings with real-run failure and token data; Plugins, CLI and MCP server are open source and inspectable

**Limitations:** Aimed at developer teams, with little value for non-technical users; Getting full value requires connecting editors and runs, not just an initial scan; The pricing page is client-rendered, so plan costs are not obvious from a quick visit
