Security gaps in AI-generated code follow predictable patterns. Disabled row-level security in Supabase, hardcoded API keys, unauthenticated API routes, and missing CORS boundaries show up repeatedly in code scaffolded by Cursor, Lovable, Bolt, v0, Replit, or Windsurf. Generic vulnerability scanners miss these mistakes because they're not looking for the specific architectural oversights that AI generators tend to produce. Vibecheck fills that gap by bundling gitleaks, semgrep, and njsscan into a single workflow, then using Claude to analyze results and explain what actually matters. Rather than presenting raw scan output, it prioritizes findings by severity and business impact. For developers shipping fast, this triage layer saves hours sorting through false positives. Getting started requires no account. Paste a live URL to check headers, TLS, CORS, and cookie flags immediately. Developers who want to scan source code can connect GitHub and run the full suite of 65 checks across 11 categories: secrets and exposure, access control, injection vulnerabilities, and server-side issues. The VS Code extension allows scanning before deployment without leaving the editor. The feature set targets real vulnerabilities in rapidly developed applications. Beyond obvious issues like hardcoded JWT tokens or SQL injection, it catches subtle misconfigurations: NEXT_PUBLIC_ secret exposure, Supabase service role keys in client code, GraphQL introspection left enabled in production, and IDOR flaws from missing ownership checks. The 50 custom checks handle patterns that open-source scanners don't catch. User testimonials reveal substantial value. One developer discovered a completely unsecured Supabase table during a pre-deployment scan. Another runs the scanner against five live products before every deploy, calling it the check they wished existed earlier in their career. The feedback emphasizes that Claude's triage actually reads like human review, not a generic wrapper around existing tools. The freemium approach—allowing live URL scanning without registration and GitHub integration with no cost—targets independent developers and small teams. The Product Hunt and VS Code Marketplace presence indicate a distribution strategy built for developers who already use AI-assisted code generation. For teams shipping applications with AI coding assistants, vibecheck addresses a real blindspot in existing security practices.

Privacy-conscious developers have few good options when it comes to AI-assisted coding tools. Most either bundle Chromium into their downloads, inflating file sizes to 150 MB or more, or require uploading projects to cloud servers. NativeCode addresses both issues by offering a compact, local-first alternative that keeps code on your machine while maintaining a minimal footprint. The product pairs a VS Code-inspired interface built on Monaco with your choice of local models running in Ollama, LM Studio, or any OpenAI-compatible server. The macOS download weighs just 7.11 MB because it leverages the system WebView built into modern operating systems — WKWebView on macOS, WebView2 on Windows — rather than shipping its own copy of Chromium. This design decision translates to meaningful storage savings without sacrificing functionality. Version 2.0 Beta, the latest release, significantly strengthens the core agent. It introduces plan mode for safe refactoring, project memory, reusable skills, pinned context, and self-review capabilities. The agent handles automatic context compaction and can access the web when needed. File and shell tool access is explicitly guarded, revealing a commitment to security over convenience. The tool supports every model its backend reports, with the ability to stream reasoning separately for models that provide it. Users can adjust thinking effort, switch backends or models without restarting conversations, and attach screenshots directly to vision-capable models. This flexibility removes friction when experimenting with different approaches or scaling up to more capable models. The business model is straightforward. NativeCode is free with no subscription requirement, no account creation, and no telemetry. The founder built this specifically because existing options either shipped unnecessary bloat or invaded privacy — frustrations many developers share. What emerges from these choices is a product designed around developer autonomy. It assumes users want control over their models, their data, and their tools, without paying for that privilege through subscriptions or data harvesting. For developers already running local LLM infrastructure or willing to set it up, NativeCode removes a major friction point: the need to choose between privacy, cost, and capability. Whether this approach catches on depends partly on whether developers embrace local inference as a default rather than a niche preference.
