Gumloop vs Sim

Gumloop

• Teams that want non-engineers to build their own agents
• Companies that prefer unlimited seats on one shared credit pool
• Agents that answer in Slack or Microsoft Teams

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

Gumloop

• There is no free plan: new accounts get a one-time 14-day Pro trial that requires a card and converts to paid unless canceled.
• Pro credits do not roll over, and agents stop at 20,000 credits a month unless pay-as-you-go is switched on.
• Bringing your own model API key removes token costs but raises the orchestration fee from 8% to 16%.
• Role-based access control, SCIM and SAML, audit logs, the admin dashboard and data exports are limited to Enterprise.

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.

Gumloop

Agents on your tools and data

Agents work across more than 300 connectors and shared company knowledge, with a choice of 35+ models or your own model API keys.

Triggers, schedules and API

App triggers and recurring schedules start agents automatically, and a REST API can run them from other systems.

Skills

Agents write reusable playbooks called skills, which can be shared across a team and synced with GitHub.

Slack, Teams and Gmail

Agents can be @mentioned in Slack channels and threads, brought into Microsoft Teams chats and channels, and used to draft and triage mail in Gmail.

Sharing and permissions

An agent built by one person can be shared with an individual, a team or the whole organization at owner, editor, viewer or use-only level.

Usage-based credits

Model tokens, compute and paid tool calls are billed at list price in credits worth $0.005 each, plus an 8% orchestration fee, or 16% when you bring your own model keys.

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.
