Vendor type	commercial	commercial
Pricing	usage	subscription
Strengths	+ Multi-surface workflow across CLI, editor plugins, web, and mobile remote control + Pay-as-you-go pricing with no markup for individual users + Extensible via plugins and MCP servers + Independent, self-described profitable company focused solely on the agent	+ Multi-surface platform spanning CLI, desktop, web, and headless CI/CD exec mode + Model routing across providers instead of single-vendor lock-in + Deep extensibility with MCP, custom droids, skills, hooks, and plugins + Multi-agent Missions for coordinated feature development
Tradeoffs	− Closed source, unlike terminal-agent alternatives such as OpenCode or Aider − Opinionated model selection managed by Amp rather than freely user-configured − Fast-changing product and branding (recently consolidated Amp Neo back into Amp)	− No free tier; entry starts at the $20/month Pro subscription − Usage is capped by rolling rate limits within each subscription tier − Enterprise-oriented platform breadth can be heavyweight for solo developers
