	GitHub Copilot B	Galileo AI B	Symphony A	Claude Code S
Tagline	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.	Prompt to UI design. Figma-ready outputs.	OpenAI's open-source daemon that turns your Linear board into an always-on coding agent factory — tickets go in, pull requests come out.	Anthropic's CLI agent. Opus-powered, operates on your repo directly.
Category	Coding	Design	Agents	Coding
Pricing	Free (limited) + $10/mo Pro + $19/mo Business	Free trial + paid plans	Free (open-source)	Part of Claude Pro/Max/Team plans
Best for	Teams with GitHub already. Devs who don't want to change IDEs.	Designers brainstorming first drafts.	Engineering teams already using Linear + OpenAI Codex who want to stop babysitting agent sessions and instead let the issue tracker drive autonomous coding at scale.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.
Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	Prompt-to-UI with real layouts Exports to Figma Faster than hand-designing from scratch	Fully autonomous ticket-to-PR pipeline: every open Linear issue gets its own isolated Codex agent without manual supervision Fault-tolerant Elixir/OTP architecture automatically restarts crashed agents and manages hundreds of concurrent runs WORKFLOW.md keeps all orchestration policy version-controlled inside the repo, so agent behavior is reproducible and reviewable like code Proven internal results: OpenAI reported a 500% increase in landed PRs on some teams within three weeks Open spec encourages community re-implementations in any language, not just Elixir	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Output needs designer polish Pricing unclear / changes often	Currently only supports Linear as an issue tracker — GitHub Issues and Jira integrations are not yet official Only OpenAI Codex is officially supported as the agent runtime; other model integrations are community-contributed and incomplete Self-hosted, Elixir-dependent engineering preview with no built-in sandboxing — not suitable for untrusted or production environments out of the box	Terminal-based — learning curve Can't be used without Claude subscription
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	B-tier. Useful for first drafts. v0 is the better bet for shipping code.	Symphony is the most architecturally serious 'issue tracker as control plane' approach yet — 15K GitHub stars in weeks confirms the idea resonates — but it's still a rough, self-hosted engineering preview that demands Elixir chops and a Linear-only workflow. (Verdict pending Phi's full review.)	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
