Modalities — Windsurf Wins

Modalities: Windsurf compared with Google Antigravity
Feature	Windsurf	Google Antigravity
Text Input	Yes. Chat and inline prompting throughout the editor.	Yes, requires free plan. Agents are driven by text prompts in the desktop command center, IDE agent panel, and CLI.
Image Upload / Vision	Yes. Paste screenshots and mockups into the chat as context.	Unknown. Vision attach in the agent panel was not confirmed on the product homepage or plans doc.
Image Generation	No. Does not generate still images.	No. Documented as an agentic coding platform, not an image generator.
Voice Mode	No. No voice interface.	No. No conversational voice loop is documented.
Video Understanding	No. Does not analyse existing video.	No. Not a video-analysis product.
Video Generation	No. Not a video generation product.	No. Not a video generation product.
File Upload (PDF, DOCX)	Yes. Reads files from the open workspace and accepts attachments.	Yes, requires free plan. Agents operate on the local workspace/codebase. That is repo context, not a PDF chat uploader.
Code Execution	Yes. Cascade runs terminal commands and tests as part of an agentic loop.	Yes, requires free plan. The CLI runs shell commands and coding agents. The IDE agent edits and verifies in the project.
Audio Input	No. No audio input.	No. No audio-file input is documented.
Canvas / Artifact Editor	Yes. The editor pane is the shared surface.	Unknown. Overlapping columns disagreed (partial vs yes); left unverified rather than copying a no.
Screen Sharing / Computer Use	No. Operates on the codebase and terminal, not the screen.	Partial. Browser-in-the-loop agents automate in-page tasks. That is computer-use-like, not a screen-share meeting product.

Memory & Context — Windsurf Wins

Memory & Context: Windsurf compared with Google Antigravity
Feature	Windsurf	Google Antigravity
Persistent Memory	Yes. Memories persist project context across sessions.	Partial. Custom agents and ~/.gemini/ plus .agents/ configs persist. That is project/user config, not ChatGPT-style memory of you.
Large Context Window	Partial. Indexes the whole repository; the usable window depends on the selected model.	Unknown. Uses Gemini agent models; no token window is published on the Antigravity plans page.
Custom Instructions	Yes. Workspace rules files steer the assistant per project.	Yes, requires free plan. Custom Agents are Markdown+YAML under .agents/agents/ or ~/.gemini/config/agents/.
Conversation History	Yes. Cascade conversations are saved per workspace.	Yes, requires free plan. Antigravity 2.0 groups conversations into Projects and can schedule messages.

Integrations — Google Antigravity Wins

Integrations: Windsurf compared with Google Antigravity
Feature	Windsurf	Google Antigravity
Web Search / Browsing	Yes. Can fetch documentation and web results as context.	Partial. Frontend pitch is browser-in-the-loop agents. That is agent browsing, not a cited search box.
Plugins / Extensions	Partial. MCP servers extend it, rather than a first-party plugin marketplace.	Yes, requires free plan. Codelab: Antigravity IDE supports local and remote MCP servers; a blog covers IDE Extensions.
API Access	No. An IDE product, not an API.	Yes, requires free plan. Antigravity SDK is a documented Python surface for custom agents on the harness.
Zapier Integration	Unknown. Not confirmed either way.	Unknown. No first-party Zapier app was checked.
Custom GPTs / Bots	Partial. Workflows and rules rather than shareable custom agents.	Yes, requires free plan. Custom Agents (Markdown) can be selected in the GUI or run via agy --agent.
Real-time Collaboration	Unknown. Not confirmed either way.	Unknown. Repo-shared .agents/ files help teams. Live multiplayer editing was not documented.
Live Social Data Integration		No. Not a live social-firehose product.
Live Citation Mapping		No. Not a cited-search product.

Developer — Google Antigravity Wins

Developer: Windsurf compared with Google Antigravity
Feature	Windsurf	Google Antigravity
Function Calling	Yes. Tool calling drives the agentic editing loop.	Yes, requires free plan. Agents use tools, MCP, shell, and subagents rather than a chat-only reply.
Streaming Responses	Yes. Responses stream into the editor as they are produced.	Unknown. Token streaming in the agent UI is not documented as an API guarantee.
Fine-Tuning	No. No custom model training.	No. You pick Gemini (and on Ultra, third-party) models. No custom-weight training product.
Embeddings API	No. No embeddings endpoint.	No. Not an embeddings API.
Structured Output (JSON)	No. Not a language model, so this does not apply.	Unknown. Artifacts exist in the IDE; JSON-schema guarantees were not documented.
Reasoning / Thinking Mode	Yes. Available through the frontier models it can be pointed at.	Yes, requires free plan. Core agent models include Gemini 3.1 Pro / 3.5 Flash. Ultra adds third-party models.
Local Execution		Yes, requires free plan. Agents run locally on the machine; models remain Google-hosted Gemini (and partners).
Open Weights		No. The harness is Google’s. Open-weight models are not the documented default.
Multi-Agent Orchestration		Yes, requires free plan. Command center runs multiple local agents in parallel; CLI manages background subagents.

Platforms — Tie

Platforms: Windsurf compared with Google Antigravity
Feature	Windsurf	Google Antigravity
Web App	No. Desktop editor only.	No. Surfaces are desktop, IDE, and CLI. A browser IDE is not the documented product.
iOS App	No. No native mobile app; the web app runs in a mobile browser.	No. Downloads are macOS, Windows, and Linux.
Android App	No. No native mobile app; the web app runs in a mobile browser.	No. No Android client is documented.

Privacy — Windsurf Wins

Privacy: Windsurf compared with Google Antigravity
Feature	Windsurf	Google Antigravity
