Glean alternatives: 8 options compared for teams with agents

Updated 9 min read

The main Glean alternatives are Microsoft 365 Copilot and Gemini Enterprise if your company lives in one suite, Atlassian Rovo or Notion’s Enterprise Search if your docs already live there, Guru for verified answers, and Onyx or PipesHub if you want open source you can host. Each one searches tools you already use. Dexio is a wiki your agents write to, and it sits beside a search tool.

We read every vendor’s pricing page and docs on 21 October 2026. For the hosted MCP servers of Atlassian, Notion and Dexio we also called each one without credentials and read the OAuth metadata it returned, to see whether a coding agent can register itself. We have not run a Glean tenant or benchmarked search quality.

What does Glean do, and why look elsewhere?

Glean indexes the tools a company already uses and answers questions from them with each person’s own access. Its site lists more than 250 connectors, an assistant, an agent builder and enterprise search, and shows no price; the button says “Get a demo”.

Glean’s Enterprise Flex pricing doc describes per-user, per-month seats with a pooled allowance of FlexCredits. Fast Mode queries are unlimited, Thinking Mode queries with standard models are included up to 100 per user per week, and usage past the allowance consumes credits. The same doc lists the MCP server among the developer surfaces whose Client API calls consume FlexCredits. Learned memories start billing on 7 November 2026.

Glean also runs a remote MCP server per tenant, so Claude, Cursor, Codex and other hosts can search Glean with each person’s access. Its MCP guide says Dynamic Client Registration is the usual path, but a tenant can allow any app, allow only approved apps, or turn registration off. New tenants start on Glean’s list of approved apps.

For a small team, two things stand out: there is no public price, so you start with a sales call, and agent traffic is metered on top of seats. In our reading, Glean is built for companies with dozens of tools more than for a 20-person engineering team.

Which Glean alternatives are there?

Alternative What it is Runs Price on the vendor’s site Agents reach it over MCP
Glean (baseline) Enterprise search, assistant, agents Glean’s cloud, or your private cloud Not published Yes, per tenant; registration set by the admin

Which alternatives fit a company already on one suite?

1. Microsoft 365 Copilot

Microsoft sells Copilot inside its business plans. On Microsoft’s small business page, Microsoft 365 Business Standard with Copilot is $23.50 a user a month and Business Premium with Copilot is $32, both paid yearly, with usage-based billing for some advanced AI features. The plans include Copilot in Word, Excel, PowerPoint, Outlook and Teams, and “AI chat grounded in your work data”.

It fits a company whose documents, mail and meetings are already in Microsoft 365, since search comes with tools people already pay for. It fits less well when engineering knowledge lives in GitHub, Linear or Notion. We did not check what Microsoft exposes to outside coding agents.

2. Gemini Enterprise

Google’s editions page lists five editions: Business for 1 to 500 users, Standard, Plus, Pay-as-you-go and Frontline (150 or more Standard or Plus users). Every edition includes permission-aware enterprise search and grounding in data from Google and third-party sources. Pooled storage and indexing runs from 2 GiB a user (Frontline) to 75 GiB (Plus). The page lists no prices.

It is the Google Workspace counterpart to Microsoft’s offer, and the same judgment applies: strongest when the company’s documents are already in Drive and Gmail.

3. Atlassian Rovo

Rovo is Atlassian’s search, chat and agents. Per Atlassian’s Rovo licensing page, it comes with Standard, Premium and Enterprise Cloud plans of Jira, Confluence, Jira Service Management, and the Service and Teamwork Collections. Each Jira or Confluence seat brings 25, 70 or 150 credits a month by plan, and Teamwork and Service Collection seats bring 250, 700 or 1,500. Rovo Search inside Atlassian apps keeps working after credits run out.

Atlassian’s MCP server is at https://mcp.atlassian.com/v2/mcp, and MCP calls that retrieve data or generate insights draw on the same credit pool as Rovo Chat and agents, most at 1 to 10 credits a call. On 21 October 2026, an unauthenticated tools/list returned 401 with a pointer to the server’s OAuth metadata. That metadata lists 40 scopes, 16 of them write or delete scopes across Jira, Confluence, Bitbucket, Loom and other products. Its authorization server advertises a registration endpoint, so a client such as Claude Code can register itself. Our Atlassian MCP guide covers setup.

Pick Rovo if your team writes in Confluence and tracks work in Jira. Look past it if most knowledge sits outside Atlassian.

Notion’s pricing page puts Enterprise Search, in beta, on the Business plan at $20 a member a month, billed yearly. It searches Notion plus connected apps such as Slack, Microsoft Teams and GitHub; Jira, Box, OneDrive, Salesforce and Asana connectors are in beta. Per Notion’s help page, a search can cover every source or be limited to one.

Notion’s MCP server is at https://mcp.notion.com/mcp. On 21 October 2026 it returned 401 to an unauthenticated call, named itself “Notion MCP (Beta)” in its metadata, and advertised a registration endpoint, and its resource metadata lists a single default scope. Per Notion’s list of supported tools, agents can search, read, create and update pages through it; see our Notion MCP guide.

It fits teams that already write in Notion. The search reaches other tools through Notion’s connectors only, so check that yours are on the list.

5. Guru

Guru is a knowledge base built around verification: cards get reviewed and kept current, and Knowledge Agents answer from them with citations. Its pricing page shows no price list; Guru scopes each engagement and includes a team of solution engineers. The page lists more than 100 integrations and “MCP delivery”.

Guru’s MCP help page says AI tools can search, retrieve and update content: create cards, draft edits, move cards and archive them, within each person’s permissions. OAuth is pre-approved for some popular apps; others may need to be allowlisted.

It fits support and enablement teams that need answers someone has signed off. An engineering team that wants agents to record decisions as they work may find the review workflow heavy.

Which open-source Glean alternatives can you self-host?

6. Onyx

Onyx is open-source search and chat over your company’s tools. The repository had 32,703 GitHub stars on 21 October 2026. Code outside its ee directories is MIT; the ee directories are under the Onyx Enterprise License. The hosted Business plan is $20 a user a month, billed yearly, with 40+ app connectors, custom agents and MCP actions. Enterprise is priced by sales.

Onyx is also an MCP server. Its docs list three tools: search_indexed_documents, search_web and open_urls. An admin enables the server on your instance’s /mcp/ URL, and self-hosted instances need HTTPS for OAuth. The tools search and fetch; they do not write back.

Of the two open-source options, Onyx has the larger community (32,703 stars against PipesHub’s 3,843) and a paid hosted plan, so it is the one we would look at first.

7. PipesHub

PipesHub calls itself “the open source Glean alternative”. The repository is Apache-2.0, with 3,843 stars on 21 October 2026, and describes a self-hosted, permission-aware workspace over Slack, Drive, Jira, GitHub, Microsoft 365 and 40+ connectors that agents can “search, grep, navigate and cite”. Its site lists an MCP server and SDKs that expose the knowledge graph to Claude, Cursor and VS Code.

It has fewer than an eighth of Onyx’s stars. It is worth a look if you want Apache-2.0 throughout, since Onyx keeps some code under a separate license.

Where does Dexio fit?

8. Dexio

Every tool above searches what people already wrote somewhere else. Dexio is where agents write what they work out: a hosted wiki of linked markdown pages that Claude Code, Codex, Cursor, Hermes, OpenClaw and other MCP clients read and write. People see what their agents know as a page graph at app.dexio.wiki, and every change is kept with the agent and person behind it. When one agent works out why a deploy fails, it writes the page, and the next agent starts from it.

The MCP server is at https://app.dexio.wiki/mcp. Its authorization server advertises a registration endpoint, so Claude and other OAuth clients can register themselves, and agents that run commands sign in through agents.md and use an API key. Per the pricing page, it is free for one person and $10 (Team) or $20 (Business) a member a month, with no usage charges and agents never counted as members. It is open source under the AGPL.

Where it does not fit: on Free, Team and Business, Dexio does not index your Slack, Drive or Jira, so it does not replace Glean’s search across tools. Everyone in a workspace, and every agent connected to it, can read the whole wiki; for per-person permissions across dozens of tools, use one of the options above. The two combine well, with search for what people wrote and the wiki for what the agents concluded. Our company brain guide compares those setups, and company wiki covers the wiki side.

How do you choose a Glean alternative?

  1. Find where your team’s knowledge lives. If most of it is in one suite or tool, that vendor’s search costs the least to add.
  2. List the agents your team runs. If Claude Code, Codex or Cursor need the same knowledge, check that the alternative has a remote MCP server they can register with. Atlassian, Notion and Dexio advertise client registration; at Glean it depends on the admin.
  3. Price agent traffic as well as seats. Glean meters MCP calls in FlexCredits, and Atlassian charges Rovo credits for MCP calls that retrieve data; Onyx self-hosted and Dexio publish no per-call charge.
  4. Decide where agents write. Every search tool here reads. Notion, Guru, Atlassian and Dexio also accept writes over MCP, and so does Glean for Library items and artifacts once an admin adds that toolset.

To connect an agent that runs commands to Dexio, send it this:

Connect yourself to my Dexio wiki. The steps are at https://dexio.wiki/agents.md: read the whole file, not a summary, and follow them.
