Modalities — Google Antigravity Wins

Modalities: Google Antigravity compared with LangChain
Feature	Google Antigravity	LangChain
Text Input	Yes, requires free plan. Agents are driven by text prompts in the desktop command center, IDE agent panel, and CLI.	Yes, requires free plan. LangChain/LangGraph agents are text-in. Fleet lets teams build agents in natural language.
Image Upload / Vision	Unknown. Vision attach in the agent panel was not confirmed on the product homepage or plans doc.	Unknown. Depends on the model you wire. Not a first-party vision SKU.
Image Generation	No. Documented as an agentic coding platform, not an image generator.	No. Framework, not an image model.
Voice Mode	No. No conversational voice loop is documented.	No. Not a voice-assistant product.
Video Understanding	No. Not a video-analysis product.	No. Not a video product.
Video Generation	No. Not a video generation product.	No. Not a video generation product.
File Upload (PDF, DOCX)	Yes, requires free plan. Agents operate on the local workspace/codebase. That is repo context, not a PDF chat uploader.	Partial. You add loaders in code. LangSmith is not a consumer PDF chat.
Code Execution	Yes, requires free plan. The CLI runs shell commands and coding agents. The IDE agent edits and verifies in the project.	Yes, requires plus plan. Deploy path: run agent-generated code in isolated sandboxes.
Audio Input	No. No audio-file input is documented.	No. Not a speech product.
Canvas / Artifact Editor	Unknown. Overlapping columns disagreed (partial vs yes); left unverified rather than copying a no.	No. Code + LangSmith traces, not a consumer canvas.
Screen Sharing / Computer Use	Partial. Browser-in-the-loop agents automate in-page tasks. That is computer-use-like, not a screen-share meeting product.	No. No computer-use desktop product.

Memory & Context — LangChain Wins

Memory & Context: Google Antigravity compared with LangChain
Feature	Google Antigravity	LangChain
Persistent Memory	Partial. Custom agents and ~/.gemini/ plus .agents/ configs persist. That is project/user config, not ChatGPT-style memory of you.	Yes, requires free plan. Own your harness, context, and memory. LangGraph is built for persistent state.
Large Context Window	Unknown. Uses Gemini agent models; no token window is published on the Antigravity plans page.	Unknown. Depends on the model you choose. No LangChain token window.
Custom Instructions	Yes, requires free plan. Custom Agents are Markdown+YAML under .agents/agents/ or ~/.gemini/config/agents/.	Yes, requires free plan. Prompts, graphs, and Fleet natural-language agent specs.
Conversation History	Yes, requires free plan. Antigravity 2.0 groups conversations into Projects and can schedule messages.	Yes, requires plus plan. LangSmith traces and datasets persist agent runs.

Integrations — Tie

Integrations: Google Antigravity compared with LangChain
Feature	Google Antigravity	LangChain
Web Search / Browsing	Partial. Frontend pitch is browser-in-the-loop agents. That is agent browsing, not a cited search box.	Partial. You add a search tool. Not a built-in cited search box.
Plugins / Extensions	Yes, requires free plan. Codelab: Antigravity IDE supports local and remote MCP servers; a blog covers IDE Extensions.	Yes, requires free plan. Model providers, tools, and 30+ Agent Server endpoints.
API Access	Yes, requires free plan. Antigravity SDK is a documented Python surface for custom agents on the harness.	Yes, requires free plan. OSS libraries plus LangSmith / Agent Server APIs.
Zapier Integration	Unknown. No first-party Zapier app was checked.	Unknown. No first-party Zapier listing was checked.
Custom GPTs / Bots	Yes, requires free plan. Custom Agents (Markdown) can be selected in the GUI or run via agy --agent.	Yes, requires free plan. You build agents (Fleet in NL, or code) and deploy them.
Real-time Collaboration	Unknown. Repo-shared .agents/ files help teams. Live multiplayer editing was not documented.	Partial. Teams share LangSmith. Not a multiplayer chat canvas.
Live Social Data Integration	No. Not a live social-firehose product.	No. No live social firehose product.
Live Citation Mapping	No. Not a cited-search product.	No. Not a cited-search product.

Developer — LangChain Wins

Developer: Google Antigravity compared with LangChain
Feature	Google Antigravity	LangChain
Function Calling	Yes, requires free plan. Agents use tools, MCP, shell, and subagents rather than a chat-only reply.	Yes, requires free plan. Tool calling is the framework. Human approval for sensitive actions on LangSmith.
Streaming Responses	Unknown. Token streaming in the agent UI is not documented as an API guarantee.	Yes, requires free plan. Streaming tokens is standard in the Python/JS APIs.
Fine-Tuning	No. You pick Gemini (and on Ultra, third-party) models. No custom-weight training product.	No. You pick models. LangChain does not train weights.
Embeddings API	No. Not an embeddings API.	Partial. Embedding integrations exist in the OSS stack. LangChain is not an embeddings vendor.
Structured Output (JSON)	Unknown. Artifacts exist in the IDE; JSON-schema guarantees were not documented.	Yes, requires free plan. Structured output parsers / tool args are a core pattern.
Reasoning / Thinking Mode	Yes, requires free plan. Core agent models include Gemini 3.1 Pro / 3.5 Flash. Ultra adds third-party models.	Partial. Deep Agents for long-running work. That is agent loops, not a user Deep Think toggle.
Local Execution	Yes, requires free plan. Agents run locally on the machine; models remain Google-hosted Gemini (and partners).	Yes, requires free plan. Open-source frameworks run locally. LangSmith cloud is optional.
Open Weights	No. The harness is Google’s. Open-weight models are not the documented default.	Partial. Framework is OSS (350M+ monthly downloads). You bring any model, including open weights.
Multi-Agent Orchestration	Yes, requires free plan. Command center runs multiple local agents in parallel; CLI manages background subagents.	Yes, requires free plan. LangGraph / Deep Agents for multi-step and multi-actor graphs.
