Gemini: plug-ins, add-ons, and third-party extensions in 2025

The Gemini extension ecosystem in 2025 has evolved into a comprehensive integration platform, combining Google’s native services with a broad catalogue of enterprise, productivity, commerce, media, and custom-built tools. This expansion positions Gemini as a central operational hub, enabling users to retrieve information, process transactions, and automate workflows directly from chat.

Gemini extensions now span multiple categories.

Gemini’s extension library is structured into functional groups that target specific workflows.

Extension class	Notable services	Primary functions	Status / release note	Admin control
Google first-party extensions	Gmail, Drive, Docs, Sheets, Slides, Calendar, YouTube, Maps, Flights, Hotels	Read and write data, embed document previews, schedule events	Rolled out with Gemini 2.0; available in web and mobile apps	Toggle: “Gemini core extensions” in Admin Console
Commerce & travel	Shopify, Kayak, Booking.com, Instacart, Uber	Real-time pricing, cart creation, ride estimates, travel bookings	Partner batch 1 release mid-2025	Per-extension disablement at organisational level
Productivity suites	Asana, Jira Cloud, Trello, Monday.com, Notion, Miro	Create tasks, update boards, insert whiteboard snapshots	Partner batch 2 release	Requires OAuth with scoped permissions
Design & media	Adobe Firefly, Canva, Figma	Generate and insert graphics, retrieve brand assets	Beta release since mid-2025	Admin-approval of asset-library access scopes
Enterprise SaaS	Salesforce Sales Cloud, HubSpot, ServiceNow, Atlassian Confluence	Query CRM, log cases, fetch documents, update knowledge bases	Pilot began late 2025	Marketplace listing, granular permission mapping
Developer tools	GitHub, GitLab, Google Cloud Build, New Relic	Open pull requests, read logs, surface incidents	SDK examples published	Repository read/write restrictions enforced
Custom internal actions	Private REST and GraphQL endpoints	Create organisation-specific workflows via the Gemini Actions SDK	SDK generally available since May 2025	Domain-restricted deployment with Admin control

Key updates in 2025 have reshaped the extension system.

Feature	Description	Impact
Partner Extensions SDK GA	Any vendor can now create JSON-returning HTTPS endpoints.	Opens opportunities for niche integrations.
Gemini Extension Store launch	Over 150 listings available directly within chat.	Improves discoverability and user adoption.
Per-conversation enablement	Extensions are turned on for a single thread instead of globally.	Reduces unnecessary data sharing.
Context size limit	Maximum 8,000 tokens returned per call, counting toward the chat’s total.	Encourages concise, optimised responses.
Minimal share privacy mode	Obfuscates identifiers, replacing them with hashed IDs.	Reduces risk of personal data exposure.
Enterprise admin controls	Allow lists, audit logs, Data Regions enforcement.	Enhances compliance and governance.

These changes have turned extensions into controlled, modular building blocks for enterprise workflows.

Developer capabilities have matured with better tools.

Developer tool	Purpose	Benefit
Rate limit settings	Default 60 calls per minute per user; higher quotas on request.	Supports heavy workloads without instability.
Streaming JSON responses	Returns large results incrementally rather than all at once.	Reduces latency for end-users.
Partner Console sandbox	Uses stubbed OAuth tokens to simulate live environments.	Allows safe pre-release testing.
Versioning system	Maintains multiple live versions of an extension simultaneously.	Prevents breaking existing workflows.

The development framework now supports rapid iteration while maintaining enterprise-grade stability.

Organisations should plan integration rollouts carefully.

Recommendation	Reason
Centralise permission reviews	Avoids uncontrolled access to sensitive tools.
Segment deployments	Limits access to extensions to relevant departments only.
Use audit logs for monitoring	Tracks extension calls to detect anomalies.
Pilot before full rollout	Ensures compatibility with internal processes.
Educate users on privacy settings	Prevents unintended data sharing during chats.

This governance approach reduces security risks and improves compliance outcomes.

The extension marketplace has become a strategic tool.

The 2025 updates transformed Gemini from a core Google service connector into a multi-ecosystem operations layer. By connecting email, documents, analytics, design tools, commerce platforms, and internal APIs directly into the conversation flow, Gemini has reduced context switching and increased workflow efficiency.

This marketplace now serves as both a command panel and an execution environment, allowing users to trigger actions and retrieve results without leaving the chat interface. For businesses, it represents an opportunity to streamline operations, reduce software fragmentation, and enforce consistent governance across all integrated tools.
