AI code reviewer that catches what others miss
PRFlow is Graphbit's code review agent built on a Rust-core, Python-first agent framework — designed for production review workflows rather than the lightweight comment bots most teams have already grown tired of. Token-based pricing with a generous launch allocation, observability and resilience baked in, and multi-LLM orchestration so you can route the actual reasoning to whichever model is best per file type. A serious option for engineering orgs that want an opinionated reviewer plugged into CI without giving up control of cost or model choice.

Anthropic's CLI agent reads your entire codebase, plans multi-file changes, runs tests, and executes complex engineering tasks autonomously from the terminal. Built for engineers who want AI that understands a full project in context rather than autocompleting in isolation — agentic by design and unusually good at not breaking things. Included with Claude Pro ($20/mo) and Max ($100/mo or $200/mo) subscriptions with weekly usage allowances, or pay per token via the Anthropic API.
Build and deploy full-stack web apps from the browser by describing what you want. Bolt writes the code, installs the packages, and runs the server — no local environment required and no setup time. Strong for rapid prototyping and for non-developers who need something working fast rather than a codebase they'll be maintaining long-term.
VS Code extension with Plan/Act modes giving fine-grained control over how autonomously the AI operates. Supports any LLM provider and costs only API tokens with no markup — with file editing, terminal access, browser use, and MCP integration built in. Five million developers and growing fast; the open-source alternative with genuine capability.
