Glean and its alternatives at a glance
| Agent | Best for | Starts at | Better than Glean at | Checked |
|---|---|---|---|---|
| Glean | Large and mid-market enterprises whose biggest AI-agent blocker is fragmented, permission-sensitive knowledge scattered across 100+ internal tools, and who want employees building department-specific agents on that indexed knowledge without writing code. | On quote source | 19 October 2026 | |
| Salesforce Agentforce | Salesforce service, sales, field-service and employee-support teams that need agents to act on CRM records and have Salesforce admin or developer capacity. | Free, then $5/user per month source | Debugs and fixes, Writes tests | 3 September 2026 |
| LangChain | Engineering teams building a bespoke, production-grade agent who want the largest integration ecosystem plus real stateful control. | Free, then $39/seat/month source | Ships it, Done-for-you service | 18 September 2026 |
| Sim | Dev teams wanting an open-source, API-first workspace to build and deploy AI agents | Free, then $25/seat/month source | Reviews code, Whole-codebase work | 3 September 2026 |
| Agno | Python developers who want an Apache 2.0 SDK with memory, knowledge, learning, guardrails and a Control Plane they run inside their own cloud account, and who are comfortable running Docker or a cloud deploy template themselves. | Free, then $150/month source | Reviews code, Ships it | 17 October 2026 |
| OpenClaw | Developers and self-hosters who already run their own infrastructure and want one personal AI agent that reaches WhatsApp, Telegram, Slack, Discord, Signal and iMessage instead of a separate app. | Free source | Ships it, Agent permissions | 21 September 2026 |

Salesforce Agentforce
Salesforce's platform for building, deploying and monitoring AI agents on top of CRM data.
From FreeWhy it's on this listFor readers whose knowledge and workflows already live inside Salesforce rather than spread across 100+ disconnected systems -- a genuine angle Glean's own fields do not name, but its own live-CRM-record integration supports directly. Agentforce agents call Salesforce Flows, Apex and MuleSoft APIs directly against live CRM records, it is genuinely model-agnostic (GPT-5.x, Claude and Gemini alongside Salesforce's own Einstein models), and it has real scale behind it -- 10,000+ agents built in its Dreamforce launch week alone. The tradeoff: consumption pricing has already changed shape multiple times since its October 2024 launch, full cross-system context requires the separately-priced Data Cloud, and full cross-system context requires the separately priced Data Cloud, so this is a lateral move for CRM-native reach rather than a verifiably cheaper one.
Where it improves on Glean
- +Debugs and fixes · YesVibes runs the test or deployment, reads the failure and iterates toward a fix rather than stopping at the error.Source ↗
- +Writes tests · YesApex test classes and LWC Jest tests are generated alongside the code, with a dedicated QA Validator sub-agent for coverage.Source ↗
- +Ships it · YesIt deploys metadata to the org itself, and through the Salesforce DX MCP Server's DevOps Center tools it commits and opens pull requests; deploy and delete stay approval-gated by default.Source ↗
Trade-offs against Glean
- −Open models · PartlyThe Salesforce-managed model list names only Anthropic, OpenAI/Azure OpenAI, Google Vertex, Amazon and NVIDIA (beta), with no Llama or Mistral, so open-weight models arrive only through the customer's own BYOLLM connection.Source ↗
- −Self-hosted · NoAgentforce runs on Salesforce's own public-cloud infrastructure, and even default model inference is operated inside the Salesforce Trust Boundary; no on-premises or customer-VPC deployment is offered.Source ↗
- −Bring your own key · PartlyOwn inference via BYOLLM from four providers with your own credentials, but requests still route through Salesforce's Models API; own encryption keys require the Salesforce Shield add-on, and the agent runtime always stays on Salesforce.Source ↗
- 02
TaleVerified
Open-source project workspace where teams assign tasks to AI coding agents running in sandboxes.
From FreeWhy it's on this listDone-for-you service · PartlyYou run the software, but the Enterprise plan adds professional operation, installation and maintenance, with consulting and custom development charged hourly rather than a built-for-you agent.Source ↗
Where it improves on Glean
- +Self-hosted · YesSelf-hosting is the Community edition's only deployment mode and remains an option on Enterprise, on your own hardware or in Tale's cloud.Source ↗
- +Open source · YesThe platform is published under the MIT licence with its repository on GitHub, and the vendor states all product features are included in Community.Source ↗
Trade-offs against Glean
- −Runs autonomously · PartlyAn agent completes a task unattended and posts its report, but it must stop at In review and cannot approve its own result, so a person or a separate reviewer agent closes the loop.Source ↗
- −In your editor · PartlyThere is no Tale IDE extension; instead opencode and Claude Code are pointed at Tale as a model provider and MCP tool server from your own editor.Source ↗
- −Certifications · PartlyRuler GmbH holds ISO/IEC 27001 covering Tale Enterprise and offers a GDPR/FADP DPA with a custom DPA on Enterprise, but no SOC 2 report is published.Source ↗
- 03
LangChain
Open source agent frameworks plus LangSmith, a hosted platform to trace, evaluate, deploy and govern agents.
From FreeWhy it's on this listShips it · YesLangSmith Deployment runs agents in production with one-click deploy from Studio and a control-plane API; the free Developer plan shows Deployment as N/A, so shipping starts at Plus.Source ↗
Where it improves on Glean
- +Done-for-you service · PartlyYou run the software yourself on every self-serve plan; only Enterprise buyers get LangChain engineers, architectural guidance and team training alongside the product.Source ↗
- +Agent permissions · YesHuman-in-the-loop interrupts gate agent actions in the framework, dcode gates code execution behind approval modes, and Fleet agents can run as themselves or as the calling user.Source ↗
Trade-offs against Glean
- −In your editor · PartlyLangSmith Studio is the vendor's own agent IDE for visualising and debugging graphs, but no plugin for VS Code, JetBrains or Cursor is documented; dcode is a terminal, not an editor.Source ↗
- −Bring your own key · PartlyYou can bring your own provider keys through the gateway on every plan, or buy inference as Gateway Credits, but Engine refuses your keys and bills its model use as compute units.Source ↗
- −Audit log · PartlyA tamper-resistant log of administrative actions with a UI, an API and 400-day retention exists, but the vendor states plainly it is Enterprise-only: Developer and Plus get nothing.Source ↗
- 04
SimVerified
Open-source AI workspace for building, deploying and running agents across 1,000+ integrations.
From FreeWhy it's on this listReviews code · YesReview Code mode checks out an existing PR read-only and submits a GitHub review with inline comments.Source ↗
Where it improves on Glean
- +Whole-codebase work · YesCreate PR clones the whole repository into a sandbox with full read, shell, edit and git access.Source ↗
- +Ships it · PartlyDeploys what it builds: workflows ship as versioned REST endpoints, with deploy/undeploy/rollback callable from CI. What ships is workflows, not code.Source ↗
Trade-offs against Glean
- −Writes code · PartlyGenerates workflow logic, blocks and schemas from a plain-English description, not application source code.Source ↗
- −In your editor · PartlyNo IDE extension; instead deployed workflows are callable from Cursor, VS Code, Claude Code and Codex as MCP tools.Source ↗
- −Admin controls · PartlyEnterprise Access Control groups restrict which model providers and block types users may run, enforced in the executor; not available below Enterprise.Source ↗
- 05
Agno
Python SDK, self-hosted AgentOS runtime and hosted control plane for running agents as a service.
From FreeWhy it's on this listReviews code · YesCode review over a diff is one of the documented coding-agent patterns.Source ↗
Where it improves on Glean
- +Ships it · PartlyIt ships agents, not arbitrary code: templates include deploy scripts and AgentOS turns a registered agent into a service in your own cloud.Source ↗
- +Done-for-you service · PartlyYou run the software yourself on every plan; hands-on help building your product agent and the ChatGPT and Claude apps is an Enterprise add-on, not the default engagement.Source ↗
Trade-offs against Glean
- −Writes code · PartlyAgno does not author application code itself; its platform template ships coding-agent skills that write and edit the agent code for you.Source ↗
- −In your editor · PartlyThere is no IDE extension; instead a running AgentOS connects to editor-based coding agents such as Cursor, Claude Code and Codex as an MCP connector.Source ↗
- −Pooled budget · NoThere is no shared consumption balance to pool because nothing is metered; seats are per person and usage inside a connection is unlimited.Source ↗
- 06
OpenClaw
Open-source personal agent runtime you host yourself and message from any chat app.
From FreeWhy it's on this listShips it · PartlyA Gateway publication broker creates commits, pushed branches and pull requests from a session; nothing in the docs claims it deploys.Source ↗
Where it improves on Glean
- +Agent permissions · YesExec policy spans deny, allowlist, ask, auto and full modes with approval prompts, allowlist bindings and a deny fallback when no approval UI is reachable, so how much runs unattended is configurable.Source ↗
- +On the command line · YesA global npm CLI plus a CLI-only installer give a full terminal surface, with subcommands for onboarding, gateway, agents, approvals, backup and MCP.Source ↗
Trade-offs against Glean
- −How it meters · NoThe vendor meters nothing at all: no seats, credits, tokens or tasks are billed, and your only running cost is whatever the model provider you connect charges.Source ↗
- −Audit log · PartlyThere is a bounded audit ledger of runs, tool actions and approval decisions, but it is metadata only and the richer execution-identity recording is off by default and must be enabled.Source ↗
- −Single sign-on · PartlyOpenClaw has no built-in SAML or OIDC login; instead it delegates authentication to an identity-aware reverse proxy such as Pomerium or oauth2-proxy and maps the forwarded identity to operator scopes.Source ↗
What to watch for
- GleanSales-led enterprise-only. No self-serve signup or published pricing at any deployment size.
- Salesforce AgentforceBest fit is a Salesforce-first environment. A CRM-neutral team will need separate integrations and may not recover the platform's data and workflow advantages.
- LangChainFast-moving: core abstractions have changed across major versions, so older tutorials can mislead.
- SimDetails here come from the vendor's own site; independent reviews are not available yet.
- AgnoThe 3.2-microsecond / 5.2 KiB figure is measured on Agno's own published harness. Independent, reproducible benchmarks against LangGraph on neutral hardware were not found.
- OpenClawA commenter, not the reviewer, described OpenClaw's memory as breaking down with longer-term usage, based on secondhand reports rather than direct hands-on testing
