Seven alternatives to Anthropic's Claude Tag, grouped by the shape of the product rather than a feature count, with what each one is good at and where it stops.
We build AgentConnect, an open-source platform for running multiple agents alongside a team, so we have an obvious interest in this comparison. We have tried to make it useful anyway: every claim below links to a vendor's own documentation, the section on where AgentConnect falls short is not decorative, and there are several cases listed where we think Claude Tag or another product is the better choice.
Claude Tag is good. Most teams that go looking for an alternative are not unhappy with the model — they have hit a boundary in the product around it. The useful question is which boundary, because each one points at a different category of replacement.
The short version: the main alternatives to Claude Tag are AgentConnect, OpenTag, and Buzz if you want open source and self-hosting; Viktor if you want one assistant across a wide SaaS surface; Devin if the work is mostly code; and Raft or Grok Bot if you are willing to adopt a separate app. To pick between them, count the roles you need, then count the places you need them. One role in one Slack workspace is what Claude Tag is built for. More than one role, or more than one place, and you are shopping for a different shape of product.
We asked the same five questions of each one:
We did not benchmark output quality. Every product here can call a frontier model, and on a given task the difference between them is mostly the context and tools you gave the agent, not the wrapper around it. Benchmarking wrappers against each other would produce a number we could not defend.
When these facts were checked. We verified the Claude Tag, Viktor, Grok Bot, and Devin entries against vendor documentation on 2026-10-29. The OpenTag, Buzz, and Raft entries were last verified in August 2026. Pricing and product shape move quickly here, so follow the links before you budget: Devin retired two plans during 2026, and xAI added shared Bots and Slack support to Grok Bot in late October. Both changes broke an earlier draft of this article.
Three different products get searched for under similar names, and they are not substitutes for one another:
@Claude in a channel and it
works on the task asynchronously, using the tools an administrator granted it. This is
what this article compares.The confusing part is that these overlap. Anthropic describes Claude Tag as "the beginning of an evolution of Claude Code", and several products below run coding agents inside team chat, which puts them in both searches. If what you actually want is a coding agent in your terminal, this list is not for you.
Worth being precise about, because several alternatives are worse at these things.
Anthropic also reports that 65% of its product team's code is created by its internal version of Claude Tag. That is a vendor's self-reported figure about its own engineering culture, and it does not establish what the product will do for a team with a different codebase and different review norms — but it does suggest the pattern is being used seriously rather than demoed.

Teams leave Claude Tag for six reasons, and each is a product boundary rather than a model weakness:
Feature matrices in this category tend to mislead, because the products are not variations on one design. They are four designs, and most of the frustration we hear about comes from a team adopting the wrong shape rather than the wrong vendor.
1. One assistant in your chat tool. A single capable entity that lives in Slack or Teams, connects to many SaaS tools, and does tasks conversationally. Claude Tag, Viktor. Best when the work is broad and generalist, and one well-configured assistant is the point.
2. A roster of agents in your existing tools. Several named agents with distinct roles, models, tools, and permissions, working in the conversations and repositories a team already has open, and able to call one another. AgentConnect, Grok Bot. Best when different jobs genuinely need different configuration.
3. A router from chat to a coding agent. Chat is the trigger surface; the real work is a coding task that runs elsewhere and reports back. OpenTag, Devin. Best when the work is almost entirely "change this code".
4. Its own workspace. The product brings its own app, and the team moves part of its work there. Raft, Buzz. Best when you want a purpose-built surface and are willing to add one.
A useful rule falls out of this. Count the roles, then count the places. One role in one place: shape 1, and Claude Tag is a strong default. Several roles that need different models, tools, or access: shape 2. One kind of work, mostly code: shape 3. Willing to change where people work: shape 4.

What it is. The open-source, multi-agent alternative to Claude Tag. You give each agent a role, and people and agents work together in the conversations the team already has open — Slack, Telegram, Discord, Lark — and in GitHub, GitLab, Gitea, and Linear. Agents can call one another, keep their own memory and skills, and start work from a message, issue, pull request, webhook, or schedule. Each agent's runtime, model, workspace, tools, machine, and sandbox policy are configured independently, so a triage agent and a security reviewer are two agents rather than two deployments. Claude Code, Codex, Grok Build, DeepSeek, Pi, or any ACP-compatible agent run side by side, and swapping one does not rebuild the workflow around it.
Best for. Teams that need more than one kind of agent, that work across more than one platform, or that want agent execution on infrastructure they operate. Common patterns: issue and incident triage in a shared thread with the right specialists pulled in; support that starts in Telegram, involves engineering from a trusted Slack workspace, and returns the answer where it started; recurring operations that run on a schedule and escalate exceptions to a human; and customized code review where a general reviewer runs on every pull request and an architecture or security reviewer joins only when the change warrants it.
Limits. You operate it, which is real setup work, and there is no ambient mode — agents start from a mention, an event, or a schedule rather than volunteering. The fuller list is below.
Pricing. Free under Apache-2.0 and self-hostable with Docker Compose or the official Helm chart; you pay your own model providers. A hosted Cloud is available if you would rather not operate it.
What it is. An open-source router. A mention in Slack or Lark dispatches work to a coding agent, and the result comes back to the originating thread. It supports multiple coding-agent executors, which is not the same thing as a team of agents with distinct roles — the executors are interchangeable workers behind one entry point.
Best for. Teams whose use case really is "run a coding agent from chat", who want something small and self-hosted, and who do not need per-agent roles or access boundaries.
Limits. Telegram, Discord, and Teams are previews. GitHub and GitLab work through manual webhook configuration. No per-agent sandbox policy.
Pricing. Free, self-hosted.
What it is. An AI coworker that lives in Slack and Microsoft Teams, aimed at business operations rather than engineering specifically. Its pitch is breadth of integration — it advertises 9,800+ connected tools — and it does work in those tools rather than returning drafts.
Best for. Operations, sales, marketing, and support teams who want one capable assistant across a very wide SaaS surface, and who are not trying to run differently configured agents.
Limits. It is one assistant, not a roster, and the model choice is Viktor's rather than yours — its pricing page describes credits as reflecting model work across Anthropic, OpenAI, and others, not a setting you pick per task. Credit consumption is the budgeting risk: Viktor's own pricing page puts quick tasks at 100–300 credits, complex workflows at 500–1,500, and full projects at 2,000–5,000, so a 40,000-credit month covers a wide range of actual work depending on what you ask for.
Pricing. Free to start with up to $100 in credits and no credit card. Team is $100 per month for 40,000 credits shared across the workspace with no per-seat charge, and unused credits roll over. Enterprise is custom. (Viktor pricing)
What it is. Block's open-source agent workspace, with its own app and built-in Git. Multi-agent, and open about which runtime it talks to.
Best for. Teams that want an open-source, self-hosted agent environment and are happy to adopt a new surface rather than work inside Slack.
Limits. You are adding an app, which is the cost of shape 4 — work that happens there is not in the channel where the rest of the team is talking. Remote container deployment is supported, but local agents are not sandboxed by default, which matters if you are reasoning about blast radius.
Pricing. Free, self-hosted.
What it is. A hosted agent platform with its own workspace and messaging, supporting multiple agents and multiple providers.
Best for. Teams that want a managed, purpose-built environment and do not have a self-hosting requirement.
Limits. Closed source and hosted only. Agents are not sandboxed per agent, and there is no separate control over which agents may discover or call one another.
Pricing. See vendor pricing.
What it is. xAI's persistent Bots — named AI teammates with jobs and compounding
context, each working on a cloud computer with a browser, filesystem, and terminal. Bots run
in parallel, message each other, share context in group chats, and hand off ownership of a
task. A Bot can be shared with a Cursor team and brought into that team's Slack, where
teammates mention it in channels and threads; you can also start work by tagging @bot on X.
Best for. Teams on Cursor who want durable, named agents that keep browser sessions and app logins, and whose work is mostly computer use across web tools and SaaS apps.
Limits. Two things to be clear about. First, the collaboration model is one Bot with many private conversations rather than one shared transcript: each person's chat with a shared Bot is private, and the owner and Managers cannot read it. Shared work is visible in Slack channels and threads, not in the app. Second, and more important for a security review: your own Bots do not get a computer each. xAI's documentation states that the cloud computer is attached to your account rather than to an individual Bot, and that files, browser sessions, and app logins on it are reachable by every Bot you run. Isolation between users is strict; isolation between your own Bots is not a boundary. If you were planning to give one Bot production credentials and hold another at a lower trust level, that plan does not work. Shared Bots must run in the cloud — a Bot running on your own computer cannot be shared.
Pricing. Included with every paid individual Cursor plan and the Cursor Teams plan, via a linked SuperGrok subscription, or with a seat on a self-serve Grok Business plan. Usage resets weekly. A shared Bot's reply is billed to the usage of whoever it is answering. (Grok Bot overview, Shared Bots)
What it is. Cognition's software engineering agent, with Slack and Teams integrations that let you start and follow sessions from chat. Connects to GitHub, GitLab, and Bitbucket, with custom Git provider support, plus Linear and Jira.
Best for. Teams buying a managed coding agent, where chat is a convenient front door rather than the collaboration surface. Enterprise controls are mature: SAML/OIDC SSO, centralized admin, teamspace isolation, and deployment into your own VPC.
Limits. It is one product doing one kind of work well. You choose the model but not the agent runtime — it is Devin either way — and sessions are isolated rather than persistent agents, so there is no roster of differently configured teammates that can call one another. Closed source.
Pricing. Free tier; Pro $20/month; Max $200/month; Teams $80/month plus $40/month per full dev seat, up to 200 users; Enterprise custom. Paid plans include a usage allowance that refreshes daily and weekly, with extra usage purchasable at API pricing. Note that Cognition retired its earlier Core and Team plans during 2026, so older comparison articles — and several that are still ranking — describe a lineup that no longer exists. (Devin pricing)

Notes on the rows that are easy to misread:
We would tell you to stay on Claude Tag if:
Work through this in order and stop at the first match.
Is there an open-source alternative to Claude Tag? Yes — AgentConnect, OpenTag, and Buzz are all open source and self-hostable. They are different shapes: AgentConnect runs a roster of agents in your existing chat and code tools, OpenTag routes a chat mention to a coding agent, and Buzz provides its own workspace.
Can I use Claude Tag outside Slack? Not currently. Anthropic describes Slack as where it is starting and says it intends to expand. If you need Telegram, Discord, Lark, or Microsoft Teams today, you need a different product.
Does Claude Tag cost extra? Anthropic has not published a separate price for Claude Tag. It is available in beta to Claude Team and Enterprise customers, and administrators set token spend limits for the organization and for individual channels.
Can I run a non-Anthropic model in Claude Tag? No. Claude Tag works with Opus 4.8. If model choice is the requirement, Devin lets you pick among providers while still running Devin as the agent; AgentConnect, OpenTag, Buzz, and Raft let you change the agent runtime as well as the model.
What is the difference between Claude Tag and Claude Code? Claude Code is a coding agent you run in a terminal or IDE against a checkout. Claude Tag is a Slack teammate that works asynchronously on tasks for a channel. Anthropic positions Tag as an evolution of Claude Code toward team work.
Can more than one agent work in the same conversation? In Claude Tag, no — a channel has one Claude. Of the products compared here, AgentConnect, Buzz, Raft, and Grok Bot all support several agents that can call one another. Buzz and Raft do it in their own app; Grok Bot does it in its app and in Slack; AgentConnect does it across Slack, Telegram, Discord, Lark, and the code hosts as well.
If this was useful and you want to look at the open-source option, star AgentConnect on GitHub — it is the main way other teams find the project.
