3 alternatives to Glean in 2026

Glean offers a range of enterprise solutions centered on knowledge discovery and intelligent automation. 

This includes an agent builder that helps organizations create, deploy, and monitor AI agents; an enterprise search platform that can answer questions in plain language using semantic, permissions-aware search; and an AI assistant that operates on top of the search foundation to perform actions on users’ behalf.

To help you determine whether Glean is the right fit for your specific integration and automation needs, we’ll compare it to the best alternative options.

Merge 

Merge offers two products: Merge Unified and Merge Agent Handler. 

The former lets you add hundreds of integrations to your products through a single, unified API; the latter lets you add thousands of enterprise-grade tools to your agents.

Top features

• Merge Unified offers 220+ customer-facing integrations across 7 categories to help you support all of the integrations your customers and prospects need

• Merge Agent Handler offers thousands of pre-built tools across dozens of connectors, but you can also easily modify any tool and auto-generate your own connectors with AI

• Both products offer Merge Link, a UI component that lets users authenticate to a given application, and security features like audit trails and fully-searchable logs to help your team troubleshoot and prevent issues

When to choose Merge over Glean

• You want transparent pricing. Glean currently doesn’t explain their pricing models for any of their products, while Merge outlines how each plan is priced for both Merge Unified and Merge Agent Handler

• Your product needs to support numerous integration use cases. Glean’s product integrations are geared towards supporting enterprise search. This would force you to look for an additional integration vendor if you need to, say, add HRIS connections to automate user provisioning 

• You need to offer intuitive integration linking flows. Unlike Glean, Merge provides clear instructions on authenticating to each app on your behalf. Merge can even provide white-labeled guides to improve your authentication success rate

Composio

Similar to Merge Agent Handler, Composio lets you add thousands of tools to your agents and observe any tool call.

Top features

• Offers Hundreds of MCP servers across categories, from Gmail to GitHub to Slack

• Enables you to build custom agentic flows with Rube, Composio’s AI-powered automation platform, once you’ve connected your agent to a tool(s)

• Provides Python and TypeScript SDKs, plus framework adapters for LangChain and CrewAI to plug tools into existing agent stacks

When to choose Composio over Glean

• You want to test and validate the platform first. Composio’s pricing plans include a free option (“Totally Free”), allowing you to make thousands of tool calls and see if they work as expected across your agentic use cases

• You need visibility on available MCP servers. Unlike Glean, Composio provides an up-to-date library of the MCP connectors and tools they provide on their site, making it easy to evaluate what’s available before deciding to adopt the platform

• You'd prefer a vendor that’s solely focused on one solution. Glean’s team may be stretched thin across its products and their associated features. By contrast, Composio is purpose-built for agent connectivity, so they’re likely better positioned to iterate faster and improve further over time

Workato

Like Glean, Workato offers a wide range of products, from an agent builder product (Workato Genies) to an enterprise search solution (Workato Go) to their core integration platform as a service (iPaaS) offering.

Top features

• Thousands of automation templates to help you ideate and implement workflow automations quickly 

• Lets you convert recipes, or workflow automations, into fully-managed MCP servers through their new product, “Workato Enterprise MCP”

• Workato Genies lets you create custom AI agents from scratch or build off of templates provided by Merge

When to choose Workato over Glean

• Your team is already comfortable with Workato. Workato’s products offer a similar UX. For example, they consistently require you to build and maintain recipes. To that end, if your team already uses a Workato product, you’ll likely experience a faster time-to-value by choosing Workato over Glean

• You need to support use cases beyond enterprise search. Glean offers roughly 100 connectors focused on data and knowledge sources, while Workato provides 1000s of connectors that cover a wide range of business applications

• You’re looking for a full-lifecycle API management platform. Workato supports this product line while Glean doesn’t (and likely won’t any time soon)
