Cursor + Antigravity — Current State Brief

Date: 2026-04-14

For: Mark

Scope: What's new since mid-March 2026, what to update, what to install.

1. Cursor — the big one

Current version: Cursor 3.1 (released 2026-04-13, yesterday)

Changelog: https://cursor.com/changelog

Cursor 3.0 (Apr 2) was a ground-up redesign around agents, and 3.1 (Apr 13) is the polish pass. This is the "really, really strong update" you noticed.

What's new since mid-March

• Agents Window (3.0) — Run many agents in parallel across local, git worktrees, cloud VMs, and remote SSH boxes. This is the headline feature: the IDE is no longer built around a single chat — it's built around a fleet.
• Agent Tabs + Tiled Layout (3.0/3.1) — Side-by-side or grid view of multiple running agents. You can literally watch 4 agents work 4 problems at once.
• /worktree command — Auto-creates an isolated git worktree so an agent's changes don't touch your working tree until you merge.
• /best-of-n command — Runs the same task in parallel against multiple models in isolated worktrees, then compares outcomes. This is a God-mode feature — it's basically built-in A/B testing for model choice.
• Design Mode — Point-and-click annotation on a live browser UI to tell the agent exactly which element to fix. Eliminates the "the button on the top right, no, the OTHER top right" round-tripping.
• Self-hosted Cloud Agents (Mar 25) — Cloud agents can now execute inside your own network/VMs. Relevant if TP3 ever needs agent access to Apex without tunneling.
• Bugbot MCP support (Apr 8) — Bugbot (Cursor's PR reviewer) now pulls context from MCP servers. Resolution rate reportedly up to 78%.
• Batch voice dictation (Ctrl+M) — Records full clip then transcribes. Better for brain-dumps than streaming STT.
• Branch picker for cloud agents and diff-to-file jump (3.1) — Quality of life.

Verdict

Cursor 3 is the strongest single agentic-IDE update of 2026 so far. /best-of-n and the Agents Window are features Claude Code and Antigravity don't have.

2. Google Antigravity

Current version: 1.22.2 (released 2026-04-07)

Changelog: https://antigravity.google/changelog (main page was JS-heavy; release aggregator: https://releasebot.io/updates/google/antigravity)

What's new since mid-March

• 1.22.2 (Apr 7) — Unified permissions system for controlling agent actions. This is Antigravity catching up to Cursor's "approve once, trust always" pattern.
• 1.21.9 (Mar 30) — Onboarding bug fix.
• 1.21.6 (Mar 25) — Linux sandboxing support, improved MCP authentication, Manager deprecations. The MCP auth fix is the useful one — prior versions had OAuth flakiness on some servers.
• 1.20.6 (Mar 17) — Customizations creation fix.

Verdict

Antigravity is in a maintenance/hardening phase. Useful fixes, but no headline feature in the last 30 days comparable to Cursor's Agents Window. Its native strength — autonomous browser+terminal+editor loops with Gemini 3 — is still its moat, and nothing has eroded that.

3. Head-to-head (as of 2026-04-14)

Bottom line: Cursor has the stronger recent updates by a wide margin. Antigravity's advantage is still its tight Gemini 3 + browser-agent loop, which matters if/when you want a task run entirely hands-off without human merge steps. For everything else, Cursor 3.1 is the more powerful seat.

4. Action items for your machines

Both IDEs are installed on G16 (C:\Users\Breez\AppData\Local\Programs\cursor\ and ...\Antigravity\). Neither auto-updates reliably across major versions.

Update Cursor on G16:

Open Cursor → Help menu → Check for Updates. If it reports already current, click the gear icon → About to confirm 3.1 (build from Apr 13). If stuck on 2.x, download the fresh installer from https://cursor.com/download and run it — it upgrades in place without losing settings.

Update Antigravity on G16:

Open Antigravity → command palette (Ctrl+Shift+P) → Antigravity: Check for Updates. Target is 1.22.2. If the command is missing (older build), grab the installer from https://antigravity.google/download.

Apex: Gemini CLI is the sidecar there — no Cursor/Antigravity installs. No action.

New MCP servers worth installing (spirit of the ask)

Given tonight's chrome-devtools-mcp pain, here are the agent tools worth adding to both Cursor and Antigravity's MCP config:

1. chrome-devtools-mcp — the one that cost you hours. Install it in both IDEs' mcp.json so you never hit that wall again.

2. filesystem-mcp — scoped file access with better guardrails than raw shell.

3. git-mcp — git operations as typed tool calls, plays well with Cursor's /worktree.

4. playwright-mcp — browser automation that pairs with Cursor Design Mode.

I can wire any/all of these into both IDEs' MCP configs in a follow-up — just say the word.

Unknowns / caveats

• I could not load antigravity.google/changelog directly (page is JS-rendered). Version data for 1.22.2 comes from the Releasebot aggregator, which has been accurate for prior Antigravity releases. If the real number differs, it will be within one point release.
• Cursor 3.1 landed yesterday (Apr 13). There may already be a 3.1.1 hotfix by the time you read this — check the changelog.
• I did not verify the exact build numbers on your G16 installs; the update flow above handles that in one click.

3-line digest

• Cursor 3.1 (Apr 13) is the big one: Agents Window, /worktree, /best-of-n, Design Mode — parallel multi-agent IDE is now shipping. Update G16 via Help → Check for Updates.
• Antigravity 1.22.2 (Apr 7) is maintenance: unified permissions + better MCP auth, no headline feature. Still strongest for Gemini 3 browser-agent loops.
• Install chrome-devtools-mcp in both so tonight's frustration never repeats; I can wire it (plus filesystem/git/playwright MCPs) on request.
