## 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

## jcode

jcode is an open-source coding agent designed to live in your terminal. Its central claim is performance: the harness is written in Rust so that each extra agent session costs a few megabytes of memory instead of hundreds, and new sessions open in tens of milliseconds. That matters for workflows where the bottleneck is not model intelligence but the ability to keep twenty agents working in parallel without the machine throttling.

The project collects several capabilities usually found in separate tools: agent swarms, durable and semantic memory, background and headless execution, automatic task continuation, MCP support, prompt caching, and routing to hosted model inference or local runtimes such as Ollama and LM Studio. It also includes a self-development mode, letting the agent work on its own codebase under supervision.

jcode publishes its own evaluation research rather than leaning on public leaderboards. Its bench suite (float-print, json-unescape, utf16-transcode) is designed to be uncontaminatable because there is no memorizable answer, hard to saturate because it scores optimization depth, and continuous instead of pass/fail. The harness also tracks agent confidence at task assignment versus completion, forcing re-checks when confidence spikes unrealistically. The project is backed by Y Combinator and distributed through a one-line install script for macOS, Linux and Windows, with a desktop app in beta.

**Pricing & Plans:** Freemium with paid options. Installation and the open-source agent are free; the site lists a dedicated pricing page and an enterprise plan for larger deployments. Consult the official pricing page for current figures.

- **Rust harness with low per-session overhead:** Each additional jcode session costs megabytes rather than hundreds of megabytes, and a new session is ready for input in well under a tenth of a second, so you can run many agents on hardware you already own.
- **Agent swarms and background tasks:** Launch multiple agents in parallel, hand off long jobs to background or headless execution, and keep durable task state so work survives interruption.
- **Benchmark-driven optimization:** The jcode bench suite (float-print, json-unescape, utf16-transcode) scores optimization depth on an analog axis with no capping timeouts, so capability differences stay visible.
- **Confidence-checked completion:** Agents rate confidence when a task item is assigned and again when it is finished; a sudden jump triggers forced re-verification instead of blind acceptance.
- **Flexible model routing:** Works with hosted model inference or local runtimes such as Ollama and LM Studio, plus MCP support and prompt caching for efficient long sessions.

**Strengths:** Open-source agent with a one-command install for macOS, Linux and Windows; Memory footprint per extra session is dramatically lower than typical terminal agents; Runs many parallel agents and durable background tasks from one terminal; Supports local model runtimes and MCP, so it is not locked to a single provider

**Limitations:** Terminal-first interface is not aimed at users who want a graphical editor; Its benchmark claims are self-published, so independent verification is limited; Extracting full value requires comfort with shells, model configuration and agent orchestration
