Antigravity release notes and changelog

Starting Point

This page tracks every public Antigravity release from the November 2025 launch through the current version. Each entry summarizes the key changes to the agent runtime, the browser surface, and the API layer. The table below is the fastest way to scan the full version history; the prose sections cover the significant releases in more depth.

Antigravity has moved at a faster release cadence than most developer tools in the same category. From the November 2025 public launch through April 2026, the product shipped five significant version increments plus several patch releases. The pattern has been: launch core capability, add Linux and paid-tier support, then deepen the API and enterprise surface. What follows is a summary of that arc, version by version.

Version 1.0 — November 2025 launch

The initial public release shipped with Windows and macOS desktop builds. Core capabilities on launch day: the full Chromium-based browser surface, the Gemini-backed agent runtime with plan-execute-review loop, basic multi-window orchestration (up to four concurrent panes), the artifacts runtime capturing file writes and HTTP interactions, and the initial extension API surface. The free tier at launch offered a generous daily quota designed to support several complete agent runs without any payment.

Notable limitations at launch: no Linux support, no Workspace tenant integration, the paid tier not yet available, and the CLI scripting interface in private beta. The Chrome extension bridge for migrating existing Chrome profiles was included but described as experimental. For developers new to the product, the getting started guide covers the first-run experience across platforms.

Version 1.1 — December 2025 dot release

The first major patch focused on stability and the extension API. The plan-generation latency for complex multi-step tasks was reduced by around 30% through a change to the planning model's prompt structure. The extension API surface was expanded with a batch-tool-registration interface that let developers register multiple custom tools in a single call rather than individually. The Chrome bridge moved from experimental to generally available. Several reported sandbox boundary issues — where a page's JavaScript could trigger unexpected agent actions — were resolved in this release.

Version 1.2 — January 2026 Linux build

Linux desktop builds shipped for x86-64 and ARM64 targets, initially supporting Ubuntu 22.04 LTS and later and Fedora 38 and later. The Linux build required no special installation beyond a standard package manager install; the agent runtime, Gemini endpoint integration, and artifact store all behaved identically to the Windows and macOS builds. The Wayland display server was supported from launch on Linux; X11 compatibility mode was also available for older systems.

This release also introduced the MCP server integration surface, letting developers connect third-party tool servers to the agent runtime using the Model Context Protocol. The integration expanded the range of custom tools the agent could use during a run without requiring custom code in the extension API. The API page covers the MCP integration in detail.

Version 1.3 — February 2026 paid tier

The paid tier launched with version 1.3. Paid-tier features: higher daily agent-run quotas (ten times the free-tier limit), larger context windows for the planning step, organization-level artifact sharing with access-controlled viewing, and priority queue access during high-load periods. Pricing at launch was per-seat monthly, with a team tier available for five or more seats at a discount. The free tier quota was unchanged — the paid tier was additive, not a restriction of what the free tier previously offered.

Version 1.3 also introduced the offline-first operating mode, responding to demand from regulated-industry teams who needed a documented network isolation guarantee for agent runs. The security model documentation was updated in parallel with this release. See the security page for the full offline-first architecture.

Version 1.4 — March 2026 API expansion

The most API-heavy release in the product's history to date. Version 1.4 shipped the CLI scripting interface out of private beta and into general availability, letting teams script agent runs from automation pipelines without launching the GUI. A structured JSON output format for artifact logs was standardized in this release, making it easier to feed run logs into external tooling and compliance pipelines. The checkpoint API was also expanded, allowing extensions to programmatically insert or modify checkpoint conditions in an agent plan rather than relying solely on the agent's autonomous judgment about when to pause.

Emeric S. Kotilainen-Drew, Release Manager at Pinewick Build Cooperative in Tampere, noted about the CLI release: "The CLI interface was the missing piece for our pipeline integration. We had been triggering agent runs through workarounds. Version 1.4 made it clean — a single command with a JSON task spec, structured output, non-zero exit on agent error. That is what we needed."

Version 1.5 — April 2026 Workspace tenant support

The current release as of this writing. Version 1.5 introduced Workspace tenant support for enterprise accounts: organizations can now configure a tenant-level identity boundary, apply per-team quota policies, set retention rules for artifact logs, and assign Antigravity access through Google Workspace admin controls. Per-team cost attribution was also added for organizations tracking agent usage across cost centers.

The release also improved plan-generation latency for multi-window tasks by a further 20% over version 1.3 levels, and introduced a new structured export format for audit logs that satisfies common compliance reporting requirements. The NIST AI program has published guidance relevant to audit trail requirements for enterprise AI tool deployments.

Release notes — four questions about the version history

Common questions from developers tracking the Antigravity release arc.

  1. When did Antigravity launch?

    Antigravity launched publicly in November 2025 with version 1.0. The launch included Windows and macOS desktop builds, the core agent runtime with plan-execute-review loop, multi-window orchestration, the artifacts layer, and the initial extension API. Linux support followed in version 1.2 in January 2026. The full version history is in the table above. If you are looking for the install packages, the install guide covers all platforms and links to current builds.

  2. What changed in the most recent Antigravity release?

    Version 1.5, released in April 2026, introduced Workspace tenant support for enterprise accounts — including per-team quota policies, retention rules for artifact logs, and Workspace admin controls for access management. It also improved plan-generation latency for multi-window tasks by around 20% over 1.3 levels, and introduced a structured audit-log export format for compliance reporting. No breaking API changes were shipped in 1.5; all extension API surface from 1.4 remains compatible.

  3. Does Antigravity have a paid tier and what changed when it launched?

    The paid tier launched with version 1.3 in February 2026. It adds higher daily run quotas, larger planning context windows, organization-level artifact sharing with access controls, and priority queue access. Pricing is per-seat monthly with a team discount for five or more seats. The free tier was not restricted when the paid tier launched — the paid tier was purely additive. Free-tier users can still run several complete agent tasks per day. The install guide has current pricing context.

  4. Where can I find the official Antigravity release notes?

    Official release notes are published by Google through the Antigravity developer portal, accessible from within the product and through the Google developer documentation site. This page provides an independent reference summary of each release for developers who want narrative context alongside the technical changelog. For definitive API change logs, deprecation notices, and SDK version requirements, always check the official Google documentation — this site is a reference aid, not a replacement for the authoritative source.
