## Sim AI

Sim is an open-source AI workspace for companies that need to build, distribute and govern AI agents rather than run isolated prompts. It brings four connected products into one environment: Workflows for designing repeatable agent logic, Knowledge Base for grounding agents in internal documents, Tables for structured data agents can read and update, and Files for shared inputs, outputs and artifacts. A Logs product traces every run for debugging and cost visibility.
Teams can build through conversation in Chat, by arranging blocks on a visual canvas, or by writing code and using the CLI. Integration coverage is broad, with 270+ connectors spanning Slack, GitHub, Gmail, Notion, Salesforce, Jira, Linear, Supabase and Stripe, alongside every major LLM including OpenAI, Anthropic, Google, DeepSeek and xAI models. The Knowledge Base automatically syncs sources such as Notion, Google Drive, Confluence, Slack, GitHub and SharePoint, so agents answer from current content instead of stale snapshots.
Governance is the other half of the product. Administrators set permission groups for models, integrations and tools, define organization and per-member spend limits, retain audit records, and configure workspace data retention. Sim Cloud is available alongside self-hosting via Docker or Kubernetes under the Apache 2.0 license, with enterprise features gated by a license. The company publishes a Trust Center covering SOC 2 Type II, ISO 27001 and GDPR, and counts Rivian and eXp Realty as customers.

**Pricing & Plans:** Free forever on Sim Cloud with 1,000 one-time credits, 1 workspace and 5 GB storage. Pro is $25 per user/month (6,000 credits/month), Max is $100 per user/month (25,000 credits/month), and Enterprise is custom. Sim Cloud credits are worth $0.005 each, and the platform is free to self-host under Apache 2.0.

- **Build agents three ways:** Create agents by describing them in Chat, arranging blocks on a visual canvas, or writing code and CLI commands, and deploy the result without rebuilding it.
- **Knowledge Base with live sync:** Sync and auto-update documents from Notion, Google Drive, Confluence, Slack, GitHub and SharePoint so agents ground answers in current company knowledge.
- **Tables and Files:** Agents read and write structured data in Sim Tables and keep files and artifacts organized in one shared store across runs.
- **Execution logs and cost tracking:** Trace every agent run block by block with success rate, latency, execution cost and failure details for debugging and reporting.
- **Enterprise governance and self-hosting:** Manage SSO and SCIM provisioning, permission groups, model and tool access, spend limits, data retention and Docker or Kubernetes deployment.

**Strengths:** Open source under Apache 2.0 with free Docker and Kubernetes self-hosting; Four plans from Free to Enterprise, so teams can start without a sales call; 270+ integrations and every major LLM in one workspace; Knowledge Base auto-syncs from Notion, Drive, Confluence, Slack, GitHub and SharePoint

**Limitations:** Credit-based Cloud pricing can be harder to forecast than flat seat pricing; Enterprise governance features such as SSO, SOC 2 controls and self-hosted enterprise licensing sit above the Free plan; With 270+ integrations and four plan tiers, first-time setup requires deliberate configuration; Small Free plan limits (1 workspace, 5 GB storage, 30-day log retention) push team use toward paid tiers

## StackAI

. What StackAI is

StackAI is an enterprise AI agent platform aimed at IT and enterprise architecture teams. It provides the building blocks to turn a manual, time-consuming process into a working agent in minutes: a visual canvas for composing agents and multi-step flows, modules for storage, vision, text-to-speech and speech-to-text, and code steps in Python or JavaScript when you need custom logic.

Agents are only as useful as the systems they can touch, so the platform ships with 500+ enterprise integrations that let an agent read, write and execute tasks inside your existing CRM, ticketing, document and collaboration tools. Knowledge bases can be grounded in your own material through document upload, web scraping, Google Drive and Notion connectors, with readers for PDF, Word and PowerPoint. Because it is model-agnostic, each step can route to whichever LLM performs best for that job.

Governance is the differentiator. StackAI is certified to SOC 2 Type II, HIPAA, GDPR and ISO 27001, offers SSO, access control and audit logs, and supports human review at critical decision points. It can run multi-tenant, in your VPC or fully on-premise. The company announced that it has been acquired by Asana, adding human-agent workflow management to the picture. Pricing is a $0 Free plan with 500 runs per month, 2 projects and 1 seat, and a custom Enterprise tier for teams that need unlimited scale, dedicated engineers and regulated deployment options.

**Pricing & Plans:** StackAI has a $0 Free plan that includes 500 runs per month, 2 projects and 1 seat with community support. The Enterprise tier is custom-priced and includes a custom number of runs and seats, unlimited projects, all features and data loaders, dedicated infrastructure and solution engineers, on-premise and VPC deployment, access control, SSO, and SOC 2 / HIPAA / GDPR compliance.

- **No-Code Agentic Workflows:** Assemble agents and multi-step flows on a visual canvas with modules for agents, storage, vision, text-to-speech and speech-to-text, then add Python or JavaScript logic when you need it.
- **500+ Enterprise Integrations:** Connect agents to 500+ enterprise systems so they can read, write and execute tasks inside your CRM, helpdesk, document stores and collaboration tools.
- **Knowledge Bases and Data Loaders:** Ground agents in your own material with document upload, web scraping, Google Drive and Notion connectors, and document readers for PDF, Word and PowerPoint.
- **Security, Governance and Deployment Choice:** Deploy in multi-tenant cloud, your own VPC or on-premise, with SSO, role-based access control, audit logs and human review at critical decision points.
- **Model-Agnostic LLM Routing:** Choose the best-performing model for each step of a workflow instead of standardising on a single provider.
- **Ready-Made Agent Templates:** Pre-built agents for SOW intake, service desk replies, anti-money-laundering screening, call compliance extraction and internal L&D Q&A.

**Strengths:** Visual no-code builder gets agents from process to production quickly; 500+ enterprise integrations let agents act inside existing systems; Model-agnostic routing across leading LLMs; SOC 2 Type II, HIPAA, GDPR and ISO 27001 certifications

**Limitations:** Advanced capabilities such as on-prem, VPC deployment and SSO are Enterprise-only; The free plan is tight at 500 runs per month, 2 projects and a single seat; No public self-serve mid-tier pricing between Free and Enterprise; Enterprise focus means more setup and governance overhead than a lightweight automation tool
