Integrations & Tool CallingNative integrations with 1,000+ services documented across communication (Gmail, Slack, Teams, Telegram, WhatsApp), productivity (Notion, Google Workspace, Airtable), development (GitHub, Jira, Linear), CRM and revenue (Salesforce, HubSpot, Attio, Gong), data and search (PostgreSQL, BigQuery, Pinecone, Perplexity, Exa) and security and IT surfaces (CrowdStrike, Okta, AWS IAM), exposed to agents as tools inside workflows; anything not built in connects through MCP support, Sim documentation introduction and integrations catalog 2026-08-02	Full
Workflow OrchestrationVisual workflow builder with first class control blocks including Router, Condition, Loop, Parallel and a Workflow block for composing sub workflows; agents reason inside Agent blocks and act through tools, and Mothership, the natural language control plane, scaffolds and edits workflows, tables and knowledge bases across the workspace, with API and SDK build paths running alongside the canvas, Sim documentation 2026-08-02	Full
Knowledge Grounding & RAGKnowledge bases are a first class workspace resource with their own documentation section covering connectors, tag based filtering, chunking strategies and retrieval debugging; agents retrieve relevant passages from customer documents to ground answers, Sim knowledge base documentation 2026-08-02	Full
Human Oversight & GuardrailsHuman in the Loop and Guardrails ship as first class core workflow blocks alongside Condition and Wait, and enterprise access control enforces which blocks and model providers each permission group can use at both the UI and execution time, Sim core blocks and enterprise documentation 2026-08-02	Full
Security, Identity & GovernanceStrong documented controls: SAML 2.0 and OIDC SSO across Okta, Entra ID, Google Workspace and ADFS, workspace roles and permission groups enforced at execution time, secrets management, organisation wide audit logs, configurable data retention, and data drains continuously exporting logs to a customer owned S3 bucket. Certification is the gap: SOC 2 and HIPAA are ASSERTED on Sim's own marketing microsite with type unspecified and no trust centre or downloadable report found on sim.ai or the documentation, which grades as asserted rather than verifiable, Sim enterprise documentation and ai4.sim.ai 2026-08-02	Partial
Observability & AuditabilityLogs record every run block by block as a first class workspace resource, with dedicated Logging and Alerts documentation, per run cost visibility, enterprise audit logs tracking configuration and security relevant actions, and data drains streaming workflow logs, audit logs and Mothership data to a customer owned S3 bucket or HTTPS webhook on a schedule, Sim logs and enterprise documentation 2026-08-02	Full
Memory & State PersistenceA dedicated Memory capability is documented alongside agents, Tables hold structured rows that workflows read, write and process as durable state, Variables carry in run state, and Mem0 and Zep ship as external memory integrations; the memory page itself was not opened in this pass so cross session semantics are graded from the surrounding documentation, Sim documentation 2026-08-02	Full
Deployment & Data ResidencyCloud hosted at sim.ai or self hosted with documented Docker Compose and Kubernetes paths, including a fully offline setup with local models through Ollama, and self hosted deployments unlock the entire enterprise feature set through environment configuration; customer controlled hosting is the strongest deployment shape in the index convention, Sim self hosting and enterprise documentation 2026-08-02	Full
Prebuilt Agents, Templates & PacksAgent skills provide reusable packaged capabilities and Mothership scaffolds complete systems from a natural language description, but no template gallery, prebuilt agent library or marketplace is documented anywhere in the documentation navigation after a two pass check, Sim documentation 2026-08-02	Partial
Triggers & Channel CoverageSix core triggers documented as their own section: Start, Schedule, Webhook, RSS Feed, Table and Sim Workspace Events, and deployments expose any workflow to the outside world as an API, a chat interface or an MCP server, Sim workflows and deployment documentation 2026-08-02	Full
Model Flexibility & RoutingFifteen plus providers documented including OpenAI, Anthropic, Google Gemini, Groq, Cerebras, DeepSeek, Mistral, xAI and OpenRouter, bring your own key at base provider pricing with no markup, and local models through Ollama or VLLM at no API cost; enterprise permission groups can restrict which providers are allowed, Sim documentation 2026-08-02	Full
APIs, SDKs & MCP ExtensibilityOpen source under Apache 2.0 with the full source on GitHub, a public API and SDKs, a Function block for custom JavaScript, custom tools, and MCP in both directions: agents consume MCP tools and any workflow deploys as an MCP server, with enterprise custom blocks on top, Sim documentation and GitHub repository 2026-08-02	Full
Testing, Debugging & OptimizationAn Evaluator block ships in the core block set as customer facing evaluation tooling, alongside Guardrails, knowledge base retrieval debugging and block by block run traces; the Evaluator page itself was not opened in this pass so depth is graded from its first class placement in the block set, Sim core blocks documentation 2026-08-02	Full
Browser & Computer UseWorkflows can drive real browsers against interfaces with no programmatic API through first class Browser Use and Stagehand integrations, with Apify and Bright Data alongside; the browser engine is an integrated third party rather than Sim's own, so the capability is delivered but not first party, Sim integrations catalog 2026-08-02	Partial

Pricing

$25/mo (Pro, 5,000 credits)

credits

Public — exactMedium variable costFree tier

Included quota

Pro 5,000 credits per month; Max 20,000; Community 1,000 one time; 1 credit equals $0.005 and every run carries a 1 credit base charge

Cost watchouts

Hosted model keys carry a 1.1x multiplier on base model pricing; SSO and access control require the separate enterprise license in production even when self hosted.

Variable cost rationale

Credit consumption scales with runs and model tokens and AI heavy workflows are dominated by token costs, but BYOK and local models let customers move model spend off Sim entirely and default caps stop runs at plan limits.

Overage / add-ons

Usage is capped at plan credits by default and runs stop; enabling on demand billing or raising the usage limit allows overage billed at the end of the period

Sales call required

Mixed (some tiers require a call)

Free / trial

Free Community plan (1,000 one time credits); free unlimited self hosting
