## 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

## SessionCast

SessionCast was built around a simple observation: AI coding agents run for minutes or hours, but developers do not want to sit at the desk waiting for them. The product places a small agent process on your PC, connects it to the SessionCast service, and mirrors the terminal output to a mobile-optimized web console. Because the console is a web page rather than a native app, it works from any phone browser, and GZip compression keeps long streaming sessions light on mobile data.

Setup follows a three-step path: sign up with a Google account, create an Agent token in the dashboard, then install and run the agent using the one-line curl script on macOS and Linux or the PowerShell installer on Windows. Once connected, sessions appear as selectable streams. Input is bidirectional, so you can answer an agent's confirmation prompt, approve a plan step, or type a fresh instruction from wherever you are, which is what separates SessionCast from read-only log tailing.

Practical uses cluster around monitoring rather than heavy authoring: watching Claude Code or Cursor work during a meeting, checking a CI/CD pipeline or Docker build on the commute, reviewing deployment logs remotely, and sharing a terminal with a colleague for remote debugging and code review. SessionCast also publishes its agent source on GitHub under the MIT License and notes in a disclaimer that the software is provided as is, so responsibility for securing your own deployment rests with you.

**Pricing & Plans:** SessionCast advertises a Free plan with a free trial entry point, so you can begin without paying. Sign-up is done with a Google account and the published agent is released under the MIT License. Consult the official pricing page for current limits on sessions and retention.

- **Real-time streaming:** WebSocket-based delivery is described as running under 50 ms latency, so AI CLI output appears on your phone as it is generated.
- **Mobile-optimized terminal UI:** The terminal interface is built responsive, so it stays usable on ordinary smartphone browsers with no dedicated mobile app required.
- **Secure access:** Google OAuth2 sign-in and per-user agent tokens mean only you can reach your own sessions.
- **Bidirectional input:** Send keystrokes and full commands from the phone, letting you answer an agent prompt or redirect a run mid-flight.
- **Multi-session switching:** Keep several terminals open at once and switch between parallel agent runs or long builds.
- **Data compression:** GZip compression keeps mobile data usage low during long streaming sessions.

**Strengths:** Solves a real, recurring problem: agent runs that outlast your time at the desk; Works in a phone browser, so there is no separate app to install; Under-50 ms WebSocket streaming makes output feel live rather than lagged; Bidirectional keyboard input goes beyond read-only log viewing

**Limitations:** Requires installing and running an agent process on your own machine before mobile access works; Security responsibility for the deployed agent sits with the user, as the developers state in their disclaimer; Free self-hosted/agent approach gives less hand-holding than a fully managed cloud terminal service; Streaming depends on your PC staying online and connected
