BundleUp

Overview

BundleUp is a unified API platform that lets developers connect to 100+ integrations with one API. Instead of building and maintaining separate connections for Slack, Jira, GitHub, Salesforce, and dozens of other tools, you write one integration and BundleUp handles the rest. It offers three API layers: a Unify API for normalized data across providers, a Proxy API for direct access to provider-specific features, and a Platform API for managing connections. Built-in authentication, rate limiting, and MCP support for AI assistants come standard.

Key Features

Unified API: Access normalized data across different providers with a single API call. Fetch chat channels from Slack, Discord, or Microsoft Teams using the same endpoint.
Proxy API: Make direct HTTP requests to any underlying integration's native API through BundleUp when you need provider-specific features.
Platform API: Manage all your integration connections, list available integrations, and handle connection lifecycle from one central interface.
Model Context Protocol (MCP) Support: Give AI assistants direct access to your connected services through both Proxy MCP and Unified MCP interfaces.
Built-In Authentication & Rate Limiting: Securely connect to third-party APIs without managing OAuth flows, tokens, or rate limits yourself.
100+ Integrations: Connect to popular tools across Chat, Git, Project Management, CRM, and Drive categories out of the box.
Python SDK: Official Python SDK (bundleup-sdk) with consistent patterns, pagination support, and error handling built in.
Multi-Category Coverage: Unified interfaces for Chat (Slack, Discord, Teams), Git (GitHub, GitLab, Bitbucket), PM (Jira, Linear, Asana), CRM, and Drive platforms.

Pros

Significant Savings in Development Time: Build one integration instead of dozens. The unified API approach turns weeks of integration work into hours.
Consistent Data Models: Normalized responses across providers mean you don't need to write transformation logic for each service.
Flexible API Layers: Choose between the Unify API for standardized access or the Proxy API when you need full provider-specific control.
AI-Ready with MCP: Native Model Context Protocol support makes it easy to connect AI agents and assistants to your existing tools.
Managed Authentication and Security: Built-in handling of OAuth, API keys, and rate limiting removes a major source of integration complexity.
Clean Python SDK: Well-structured SDK with clear patterns for pagination, error handling, and raw response access.

Cons

Limited SDK Language Support: Currently only a Python SDK is available, which limits adoption for teams working in other languages like JavaScript, Go, or Java.
Expanding Category Coverage: While Chat, Git, and PM integrations are well-documented, CRM and Drive categories have less publicly visible detail.

Use Cases

SaaS Product Integrations: You're building a SaaS product and need to offer native integrations with tools your customers already use. BundleUp lets you add Slack, Jira, GitHub, and other connections through one API instead of building each integration from scratch.
AI Agent Tool Access: You're developing an AI assistant or agent that needs to interact with external services like messaging platforms, project trackers, or code repositories. BundleUp's MCP support gives your agent standardized access to these tools without custom connectors.
Internal Tool Consolidation: Your engineering team juggles data from multiple project management, chat, and version control platforms. BundleUp provides a single interface to pull and normalize data from all of them for dashboards or workflow automation.
Multi-Platform Notifications: You need to send messages or retrieve updates across Slack, Discord, and Microsoft Teams simultaneously. The Chat Unify API handles all three with a single API call pattern.
Cross-Platform Project Tracking: Your organization uses different PM tools across teams. BundleUp's PM Unify API lets you fetch issues from Jira, Linear, and Asana through one standardized endpoint, making cross-team reporting simple.

Frequently Asked Questions

What is BundleUp?

BundleUp is a unified API platform that lets developers connect their applications to 100+ third-party services through a single, standardized API. Instead of building individual integrations for each service, you write one integration and BundleUp handles provider-specific differences behind the scenes.

What integrations does BundleUp support?

BundleUp supports integrations across multiple categories including Chat (Slack, Discord, Microsoft Teams), Git (GitHub, GitLab, Bitbucket), Project Management (Jira, Linear, Asana), CRM, and Drive. The platform covers 100+ integrations total.

What is the difference between the Unify API and the Proxy API?

The Unify API provides normalized, standardized responses across different providers, so you get the same data format regardless of which service you're querying. The Proxy API lets you make direct HTTP requests to the underlying provider's native API through BundleUp, which is useful when you need access to provider-specific features not covered by the Unify API.

Does BundleUp support AI assistants?

Yes. BundleUp includes Model Context Protocol (MCP) support, which allows AI assistants and agents to access your connected services directly. Both Proxy MCP and Unified MCP interfaces are available.

What programming languages does BundleUp support?

BundleUp currently offers an official Python SDK (bundleup-sdk) available on PyPI. The platform's APIs are also accessible via standard HTTP requests, so you can use any language that can make REST API calls.

How does authentication work?

BundleUp uses API keys for authentication. You can obtain your API key from the BundleUp Dashboard. The platform handles OAuth flows, token management, and rate limiting for third-party connections, so you don't need to manage those yourself.

How much does BundleUp cost?

Free Plan ($0/month): Includes 500,000 requests per month, 1 day of logs, unlimited connections and integrations, plus access to Proxy API, MCP API, and Unified API.
Pro Plan ($29/month): Includes 1 million requests per month (plus $5 per additional million), 2 weeks of logs, removal of BundleUp branding, unlimited connections and integrations, and full API access.

How do I get started with BundleUp?

BundleUp provides end-to-end tutorials and getting started guides in its documentation at docs.bundleup.io. You can install the Python SDK, obtain an API key from the dashboard, and begin connecting to integrations right away.
