deepsec
FreeOpen-source coding security harness
About deepsec
Vercel's CLI security harness uses coding agents to trace data flows through large codebases and surface real vulnerabilities with severity ratings — not just static-analysis noise. Pluggable agent backends (Claude, Codex), sandbox-based scaling, and the same engine Vercel runs internally on its own repos. The most credible open-source option for teams that want AI-driven security review without locking into a vendor's cloud.

Alternatives to deepsec
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.
