Agenta vs Sim

Agenta

• Teams that want to self-host their agent platform under an MIT license
• Paying by usage for a whole team instead of per seat
• Recurring jobs such as research briefs, code review and reports

Sim

• Teams building internal agents that share knowledge bases, tables and logs
• Developers who want a visual builder plus an API and a CLI
• Organizations that need to self-host an open-source agent platform

Agenta

• AI model costs are not included: you connect your own provider credentials and pay the provider directly.
• The Hobby plan stops running agents after 5,000 runs in a month and allows 2 team members and 20 evaluations a month.
• On Agenta Cloud, SSO and role-based access control start at Business ($299 a month); audit logs and custom domains are Enterprise only.
• Running agents on a Claude or ChatGPT subscription works only on a self-hosted deployment, not on Agenta Cloud.

Sim

• The Free plan's 1,000 credits are a one-time grant with no weekly refresh, and it allows 1 workspace and no teammates.
• Every workflow run carries a base charge of 1 credit, even when you bring your own model keys.
• Sim Mailer, KB Live Sync, sandboxes and Slack Connect start at Max; access control and SSO are Enterprise only.
• The desktop app is for macOS only (macOS 12 or later); on other systems Sim is used in a browser.

Agenta

Agents built by chatting

You describe the job in chat and refine the agent's instructions and skills as you go. Prebuilt templates cover engineering, support, sales, knowledge and operations.

Automations and triggers

An agent can run on a schedule or start when an event happens in a connected tool, such as a new pull request. Every run is logged with its duration and estimated cost.

Integrations, MCP and skills

Agents work across more than 1,000 integrations and any MCP server you add. Skills are reusable instruction files that can be swapped without rewriting the agent.

Harness and model choice

Three harnesses ship with it: Claude Code, Pi and Codex. Models come from your own provider accounts, including OpenAI, Anthropic, Gemini, Mistral, AWS Bedrock and Azure OpenAI.

Permissions, approvals and a secret vault

You decide which actions run automatically, which wait for approval and which are blocked. Credentials sit in a vault the agent can use but cannot read.

Tracing, evaluations and versions

Each run produces a trace of its model and tool calls, tokens and latency. Agent changes are versioned and can be compared, and evaluations include LLM-as-a-judge.

Sim

Workflow builder

Agent logic is laid out as connected blocks: agents, API calls, functions, conditions, routers, loops, parallel branches and human-in-the-loop steps.

Building in Chat

Describe a system in plain language and Chat scaffolds the workflows, tables and knowledge bases, which you then open, run and refine in the builder.

Knowledge bases, tables and files

Knowledge bases draw on uploaded documents and on connectors to sources such as Notion, Google Drive, Confluence and SharePoint. Tables hold structured rows, and files store agent inputs and outputs.

Triggers and deployment

Workflows start from a schedule, a webhook, an RSS feed or a table event, and are deployed as an API endpoint, a chat interface or an MCP server.

Logs and cost tracking

Each run is traced block by block, with token counts and cost per model, and alerts can be set on the logs.

Enterprise governance

The Enterprise plan adds SSO and SCIM provisioning, permission groups that decide which models and integrations a group may use, audit logs and data retention settings.
