+faq:
+  - q: "What's the difference between agentic AI coding tools and regular AI code completion?"
+    a: "Regular AI code completion suggests the next line or block as a developer types. Agentic AI coding tools can plan and execute multi-step changes across a codebase, run commands, and revise their approach after errors without line-by-line approval."
+  - q: "Is Cursor an agentic AI coding tool?"
+    a: "Yes. Cursor is an AI-native code editor with an agent mode for working across a project, rather than only offering inline completion."
+  - q: "Is GitHub Copilot agentic?"
+    a: "GitHub Copilot includes an agent mode in supported IDEs in addition to its original code-completion experience."
+  - q: "What is the cheapest agentic AI coding tool?"
+    a: "Several major tools have free tiers or limited free usage. For sustained use, compare each vendor's current plan, included usage, and overage model because those terms can change."
+  - q: "Can an agentic coding tool work inside a larger business workflow, not just an IDE?"
+    a: "Yes. A coding agent can write code in a project, while an agent-workflow platform can connect that output to other systems such as deployment, tracking, or team notifications."
+  - q: "Does Sim replace Cursor or GitHub Copilot?"
+    a: "No. Sim is an agent-workflow platform rather than an IDE. It fits work where a code step belongs in a broader automated system that also uses other tools, data, and deployment surfaces."

+
+## TL;DR
+
+Agentic AI coding tools plan and execute multi-step coding tasks rather than suggesting one line at a time. A developer can give one a goal such as “add OAuth login to this app”; the tool can inspect relevant files, edit code across the project, run checks, and use the output to revise its approach.
+
+The category contains two groups that are often treated as one:
+
+- **In-IDE coding agents** such as [Cursor](https://cursor.com/), [GitHub Copilot](https://github.com/features/copilot), [Claude Code](https://claude.com/product/claude-code), [Windsurf](https://windsurf.com/), and [Replit Agent](https://replit.com/agent) are designed for writing, refactoring, and shipping code from an editor or terminal.
+- **Agent-workflow platforms** such as [Gumloop](https://www.gumloop.com/), [n8n](https://n8n.io/), [Zapier](https://zapier.com/), and [Sim](https://www.sim.ai/) build broader automations. They can include a code-writing step in a process that also gathers data, sends a message, or updates another system.
+
+That distinction changes the choice. A developer shipping a SaaS product will usually want an in-IDE agent. An operations team automating a multi-app process will usually want a workflow platform. This guide covers both groups and where the line between them sits.
+
+## What makes an AI coding tool agentic?
+
+An AI coding tool is agentic when it can plan a multi-step task, take actions across a codebase, and correct mistakes without a human approving every line. That differs from traditional autocomplete, which predicts the next few tokens as a developer types, or from pasting a question into a chat window.
+
+Three capabilities separate an agentic tool from autocomplete:
+
+- **Multi-step planning.** The tool breaks a goal into file edits, terminal commands, and checks rather than completing one line.
+- **Tool use.** The agent can run terminal commands, execute tests, browse documentation, or call APIs instead of only generating text.
+- **Self-correction.** When a test fails or a command errors, the agent can read the output and revise its approach instead of waiting for a human to diagnose it.
+
+For a broader definition beyond coding, see Sim’s guide to [what an AI agent is](https://www.sim.ai/library/what-is-an-ai-agent-definition-how-it-works-and-examples).
+
+## What's the difference between an AI coding agent and an agent-workflow platform?
+
+An AI coding agent writes and modifies code in a specific project. An agent-workflow platform builds agents that can use code as one action in a larger automated process spanning apps and data sources.
+
+[Cursor](https://cursor.com/), [Claude Code](https://claude.com/product/claude-code), and [GitHub Copilot](https://github.com/features/copilot) are coding agents built around repository work. [Gumloop](https://www.gumloop.com/), [n8n](https://n8n.io/), and Sim are workflow platforms that can connect a code-writing action to a destination such as Slack, a CRM, or a database.
+
+The overlap is real. Sim includes a Function block for custom JavaScript in a workflow, and [Mothership](https://docs.sim.ai/mothership) lets users describe workflows in natural language. But Sim is not a replacement for an in-IDE coding agent when the job is writing and shipping a codebase. It fits when a code-executing step needs to participate in a larger agent that also uses other tools and data. For the distinction between agent-style automation and older rule-based systems, see [AI agents vs. RPA](https://www.sim.ai/library/ai-agents-vs-rpa).
+
+## What are the best agentic AI coding tools right now?
+
+The right pick depends on whether the work is writing code in a particular codebase or orchestrating code generation as part of a broader workflow.
+
+### In-IDE coding agents
+
+- [**Cursor**](https://cursor.com/) is an AI-native code editor built on VS Code, with an agent mode that edits across files, runs terminal commands, and works from markdown-based project instructions. It can use models from OpenAI, Anthropic, and Google depending on the task. Pricing starts with a free Hobby tier; [Pro is $20 per month](https://cursor.com/pricing) with extended agent usage, and Teams is [$40 per seat per month billed monthly or $32 annually](https://cursor.com/blog/teams-pricing-june-2026).
+- [**GitHub Copilot**](https://github.com/features/copilot) added agent mode inside VS Code and other IDEs, letting it plan changes, edit multiple files, and iterate. [GitHub’s pricing page](https://github.com/features/copilot/plans) lists Pro at $10 per user per month and Pro+ at $39 per user per month; [GitHub’s billing documentation](https://docs.github.com/copilot/reference/copilot-billing/models-and-pricing) explains its usage-based billing and states that one AI credit equals $0.01.
+- [**Claude Code**](https://claude.com/product/claude-code) is Anthropic’s terminal-based coding agent, included with Claude’s paid plans rather than sold separately. [Anthropic’s pricing page](https://claude.com/pricing) lists Claude Pro at $17 per month billed annually or $20 per month billed monthly, with Claude Code access; Max plans start at $100 per month for heavier usage.
+- **Windsurf** pricing is no longer independently verifiable on a vendor-owned Windsurf price page. [Cognition’s Devin pricing](https://cognition.com/pricing), where the product now sits, lists Free, Pro ($20 per month), Max ($200 per month), and Team ($80 per month plus $40 per seat) tiers.
+- [**Replit Agent**](https://replit.com/agent) builds and deploys applications from a prompt in Replit’s browser-based environment. [Replit’s pricing page](https://replit.com/pricing) lists a free Starter plan with daily Agent credits; Core is $20 per month billed annually ($25 month-to-month), includes $25 of monthly credits, and permits up to two agents in parallel. Pro is $95 per month billed annually ($100 month-to-month), includes $100 of monthly credits, and permits up to 10 parallel agents. Enterprise is custom.
+
+### Agent-workflow platforms that can run a coding step
+
+- **Sim** is an Apache 2.0-licensed AI workspace where a code-writing step is one block in a larger workflow. A team can describe a workflow to [Mothership](https://docs.sim.ai/mothership) in natural language, add a Function block for custom code, and deploy the finished workflow as a REST API, hosted chat experience, or MCP server. A workflow built once can be exposed as an MCP tool that a compatible coding agent calls, connecting IDE-based agents to a team’s own automations and data.
+- [**Gumloop**](https://www.gumloop.com/) is a hosted, no-code automation platform. Its own [agentic AI tools roundup](https://www.gumloop.com/blog/agentic-ai-tools) groups Cursor alongside workflow tools such as itself, n8n, and Zapier, illustrating why the category needs a clearer split. That page lists a free tier and paid plans starting at $37 per month.
+- [**n8n**](https://n8n.io/) is a fair-code, self-hostable workflow platform with a visual canvas and its own code step. [n8n’s pricing page](https://n8n.io/pricing) lists cloud Starter at €20 per month billed annually for 2,500 workflow executions and one shared project, Pro at €50 per month billed annually for 10,000 executions, and Business at €667 per month billed annually. Its Business plan includes self-hosting, SSO/SAML/LDAP, and Git-based version control; Enterprise is custom. The self-hosted Community Edition is free under [n8n’s Sustainable Use License](https://docs.n8n.io/sustainable-use-license/).

+
+## Can an agent-workflow platform replace an in-IDE coding agent?
+
+No—not for writing and shipping a codebase. In-IDE agents are designed around codebase context, git workflows, and terminal access that a general workflow platform does not try to replicate.
+
+A workflow platform adds value by connecting a coding agent’s output to the rest of a business process. A Sim workflow can place a completed code change alongside test execution, a Slack notification, and run-level tracing. The actual code work can still happen in an IDE; the workflow coordinates the systems around it. Teams deciding whether they need an agent or a simpler conversational interface can also read [AI agent vs. chatbot](https://www.sim.ai/library/ai-agent-vs-chatbot).
+
+## Are there open-source agentic AI coding tools?
+
+Yes, though “open source” means different things depending on the tool. Many prominent in-IDE coding agents, including Cursor, Windsurf, and Claude Code, are proprietary applications.
+
+Among workflow platforms that can run a coding step, licensing varies more. n8n uses its [Sustainable Use License](https://docs.n8n.io/sustainable-use-license/), which is source-available but has commercial restrictions. Sim’s core is [licensed under Apache 2.0](https://github.com/simstudioai/sim), a permissive open-source license, and Sim provides [self-hosting guidance](https://docs.sim.ai/self-hosting). For a wider comparison of licensing and deployment models, see [open-source AI agent platforms](https://www.sim.ai/library/open-source-ai-agent-platforms).
+
+## Do agentic coding tools support MCP?
+
+The [Model Context Protocol](https://modelcontextprotocol.io/) gives AI clients a standard way to connect to external tools and context. [Claude Code’s documentation](https://docs.anthropic.com/en/docs/claude-code/mcp) and [Cursor’s MCP documentation](https://docs.cursor.com/context/model-context-protocol) describe connecting to external MCP servers for additional tools and context.
+
+Sim supports MCP in both directions: it can connect external MCP servers as tools in a workflow and publish deployed workflows as MCP tools that compatible clients can call. For a full explanation of the protocol, see [what an MCP server is](https://www.sim.ai/library/what-is-an-mcp-server).
