## GitHub Sage

Open-source discovery often stalls at the same step: you land in an unfamiliar repository and have to guess how active, how relevant, and how mature it is before deciding to invest time. GitHub Sage reduces that friction with an AI assistant that lives in a side panel on your GitHub tabs and answers questions about whatever repository you are looking at.

The extension is designed for two common situations. The first is evaluating open-source projects: instead of reading an entire README and file tree, you ask about the project and get oriented quickly. The second is your own private repositories, where the assistant can help you catch up on recent changes and understand code you may not have written yourself.

GitHub Sage is published by the team behind storia.ai and is clearly labelled as not an official GitHub product. It installs as a Chrome extension, runs while you browse GitHub, and follows a freemium model according to its store listing.

**Pricing & Plans:** Freemium model according to the Chrome Web Store listing; consult the developer's site for current plan details.

- **AI side panel on GitHub:** A persistent side panel on GitHub tabs where you can ask an assistant questions about the repository you are viewing.
- **Open-source evaluation:** Quickly assess whether an open-source repository is worth adopting before you invest time in it.
- **Private repository insight:** Understand the latest changes in your own private repositories by asking about them directly.
- **Code comprehension:** Ask questions about a codebase you did not write, reducing the time spent reading unfamiliar code.

**Strengths:** Answers repository questions without leaving GitHub; Useful for fast open-source evaluation; Works with private repositories you can access; No context switching to a separate app

**Limitations:** Rated for a niche use case, so it is not a full IDE replacement; AI answers depend on repository content and can be wrong or incomplete; Only available as a Chrome extension; No public pricing detail on the listing

## 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
