Name: Stoneforge
Author: Stoneforge

Feature comparison

Feature	Stoneforge	Cursor AI
Architecture

Parallel agents	Unlimited, each in isolated git worktrees	Up to 8 in-IDE agents, plus cloud-based background agents
Agent-agnostic	Yes, works with any CLI-based coding agent	Supports multiple model providers via BYOK, but agents run inside Cursor
Workflow
Task management	Yes, plans, priorities, dependencies, automatic dispatch	Background agents can run multi-step tasks; no built-in dependency system
Automatic merge & review	Yes, Steward agents handle merge and review	Background agents push PRs; merging is manual
Inline code editing	No, agents work autonomously in terminal	Yes, inline suggestions, tab completion, chat
Cost & Control
Pricing	Free and open-source	Free tier, Pro $20/mo, Pro+ $60/mo, Ultra $200/mo, Teams $40/user/mo
Self-hosted	Yes, fully local	IDE runs locally; some AI features are cloud-dependent

Cursor AI vs Stoneforge: IDE copilot vs orchestration layer

Cursor AI and Stoneforge occupy different parts of the AI development workflow. Cursor AI is where you write and edit code with AI assistance. Stoneforge coordinates multiple AI coding agents working on separate tasks in the background. Most teams would use both, not choose between them.

Cursor AI: the AI-powered IDE

Cursor AI is a VS Code fork with deep AI integration. It provides real-time code completion, inline chat, multi-file editing via Composer, and an agent mode that can make changes across your codebase. Since version 2.0, Cursor AI also supports running up to 8 parallel agents in-IDE and cloud-based background agents that clone your repo, work in a VM, and open a PR when done.

Cursor AI is a polished, mature product with a large user base. Its interactive editing experience is strong, and the learning curve is minimal if you already use VS Code.

Stoneforge: multi-agent task orchestration

Stoneforge is a different kind of tool. It doesn’t provide an editor or code completion. Instead, it manages a queue of tasks, dispatches them to AI coding agents (Claude Code, Codex, OpenCode, or others), and coordinates the results. Each agent works in an isolated git worktree. Steward agents handle merge and review automatically.

Stoneforge is free and open-source. Its strength is structured orchestration: dependency-aware dispatch, role-based agents (Director, Worker, Steward, Daemon), and automatic merge workflows.

Using Cursor AI and Stoneforge together

The two tools complement each other:

Cursor AI for interactive work: exploring code, writing features, debugging, prototyping.
Stoneforge for background work: dispatching a batch of tasks to AI coding agents while you focus on something else.

# While you work in Cursor on the main feature...
# Stoneforge handles supporting tasks in the background

sf task create --title "Update API documentation"
sf task create --title "Refactor database queries for performance"

Where Stoneforge adds multi-agent orchestration

Cursor AI’s parallel agents work within the IDE on prompts you provide. Stoneforge manages an entire task lifecycle outside of any IDE: plans with multiple tasks, dependency ordering, automatic agent dispatch, and Steward-managed merge review. If you’re coordinating a sprint’s worth of parallel feature development across many AI coding agents, that structure helps.

If you’re working interactively on one thing at a time, Cursor AI’s built-in agent mode is likely all you need.

When to choose Stoneforge

Choose Stoneforge when you need structured task orchestration across multiple AI coding agents. If you have a backlog of tasks with dependencies, want automatic dispatch and merge, or need to coordinate agents from different providers, Stoneforge handles that. It pairs well with Cursor AI: use Cursor AI for interactive coding and Stoneforge for background orchestration.

When to choose Cursor AI

Frequently asked questions

Cursor AI vs Stoneforge: which should I use?

They serve different purposes and work well together. Cursor AI is an AI-powered IDE for interactive coding with real-time assistance. Stoneforge is an orchestration layer that dispatches multiple AI coding agents to work on separate tasks in parallel. Use Cursor AI when you want hands-on AI help while writing code, and Stoneforge when you want to run several agents on different tasks at the same time.

Can I use Stoneforge with Cursor AI?

Yes. Stoneforge orchestrates agents in the background while you use Cursor AI (or any IDE) for your own work. They don't conflict. Stoneforge works in isolated git worktrees, so its agents never touch your working tree.

Is Stoneforge a Cursor AI replacement?

No. Stoneforge is not an IDE and doesn't provide code completion or inline editing. It's an orchestration layer for coordinating multiple AI coding agents. Cursor AI is where you write code interactively; Stoneforge runs agents on separate tasks in the background.

Does Cursor AI support parallel AI coding agents?

Yes, Cursor 2.0 added parallel agent support with up to 8 in-IDE agents and cloud-based background agents. The difference is scope: Cursor AI's agents work within the IDE on a single prompt or task. Stoneforge manages a queue of tasks with priorities, dependencies, and automatic dispatch across any number of agents, with built-in merge and review workflows.

What can Stoneforge do that Cursor AI can't?

Stoneforge manages a full task lifecycle: plans, priorities, dependencies, automatic dispatch to AI coding agents, and Steward-managed merge and review. It also works with any CLI-based agent (Claude Code, Codex, OpenCode), not just one IDE's built-in models. Cursor AI offers a much richer interactive coding experience that Stoneforge doesn't try to replicate.
