Bolt New vs Google Antigravity
A feature-by-feature comparison of Bolt New and Google Antigravity across 7 capability categories.
Modalities — Bolt New Wins
| Feature | Bolt New | Google Antigravity |
|---|---|---|
Text Input | Yes. Auto populated | Yes, requires free plan. Agents are driven by text prompts in the desktop command center, IDE agent panel, and CLI. |
Image Upload / Vision | No. Auto populated | Unknown. Vision attach in the agent panel was not confirmed on the product homepage or plans doc. |
Image Generation | No. Auto populated | No. Documented as an agentic coding platform, not an image generator. |
Voice Mode | Partial. Auto populated | No. No conversational voice loop is documented. |
Video Understanding | No. Auto populated | 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. Auto populated | Yes, requires free plan. Agents operate on the local workspace/codebase. That is repo context, not a PDF chat uploader. |
Code Execution | Yes. Auto populated | Yes, requires free plan. The CLI runs shell commands and coding agents. The IDE agent edits and verifies in the project. |
Audio Input | No. Auto populated | No. No audio-file input is documented. |
Canvas / Artifact Editor | Yes. Auto populated | Unknown. Overlapping columns disagreed (partial vs yes); left unverified rather than copying a no. |
Screen Sharing / Computer Use | No. Auto populated | Partial. Browser-in-the-loop agents automate in-page tasks. That is computer-use-like, not a screen-share meeting product. |
Memory & Context — Bolt New Wins
| Feature | Bolt New | Google Antigravity |
|---|---|---|
Persistent Memory | Yes. Auto populated | Partial. Custom agents and ~/.gemini/ plus .agents/ configs persist. That is project/user config, not ChatGPT-style memory of you. |
Large Context Window | Yes. Auto populated | Unknown. Uses Gemini agent models; no token window is published on the Antigravity plans page. |
Custom Instructions | No. Auto populated | Yes, requires free plan. Custom Agents are Markdown+YAML under .agents/agents/ or ~/.gemini/config/agents/. |
Conversation History | Yes. Auto populated | Yes, requires free plan. Antigravity 2.0 groups conversations into Projects and can schedule messages. |
Integrations — Google Antigravity Wins
| Feature | Bolt New | Google Antigravity |
|---|---|---|
Web Search / Browsing | Yes. Auto populated | Partial. Frontend pitch is browser-in-the-loop agents. That is agent browsing, not a cited search box. |
Plugins / Extensions | No. Auto populated | Yes, requires free plan. Codelab: Antigravity IDE supports local and remote MCP servers; a blog covers IDE Extensions. |
API Access | Partial. Auto populated | Yes, requires free plan. Antigravity SDK is a documented Python surface for custom agents on the harness. |
Zapier Integration | No. Auto populated | Unknown. No first-party Zapier app was checked. |
Custom GPTs / Bots | No. Auto populated | Yes, requires free plan. Custom Agents (Markdown) can be selected in the GUI or run via agy --agent. |
Real-time Collaboration | No. Auto populated | 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
| Feature | Bolt New | Google Antigravity |
|---|---|---|
Function Calling | No. Auto populated | Yes, requires free plan. Agents use tools, MCP, shell, and subagents rather than a chat-only reply. |
Streaming Responses | Yes. Auto populated | Unknown. Token streaming in the agent UI is not documented as an API guarantee. |
Fine-Tuning | No. Auto populated | No. You pick Gemini (and on Ultra, third-party) models. No custom-weight training product. |
Embeddings API | No. Auto populated | No. Not an embeddings API. |
Structured Output (JSON) | No. Auto populated | Unknown. Artifacts exist in the IDE; JSON-schema guarantees were not documented. |
Reasoning / Thinking Mode | No. Auto populated | 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
