Architectural decay in AI-assisted coding happens fast. As code agents like Claude Code and Cursor generate multiple edits across dozens of tool-calls in a single session, violations of project structure can slip through undetected until they accumulate into technical debt. Archlint addresses this by moving architectural validation from the CI pipeline into the agent's editing loop, catching violations the moment they occur so corrections happen immediately rather than weeks later during code review. The tool works by declaring a project's layer structure and dependency rules upfront—defining which components can import from which others—then validating every edit the agent makes against those rules in real time. It supports six languages: Python, TypeScript and JavaScript, Go, Rust, Java, and C#, with import resolution sophisticated enough to handle real-world complications like tsconfig path aliases, Python src/ layouts, and Go module paths. The system doesn't require an architectural blueprint; teams new to Archlint can run its initialization tool to generate rules from their existing directory structure and import patterns, then refine them in minutes. What distinguishes Archlint is its positioning as a guardrail for AI agents rather than a general architecture linter. The product's own telemetry shows an 86 percent self-correction rate—meaning the agent detects violations and fixes them within the same session 14 times out of roughly 16 when drift is introduced. This metric captures something important: the tool's value isn't primarily about stopping bad code but about catching it early enough that remediation is trivial. The implementation is spare. Archlint is pure Python with no external dependencies, keeping deployment friction low and the attack surface minimal. It integrates with both Claude Code and Cursor, delivering per-edit feedback in Claude Code and end-of-turn summaries in Cursor. For teams adopting it into existing codebases with established architectural violations, the baseline mode allows rules to be adopted gradually—flagging only new drift rather than demanding immediate compliance with historical violations. The product is sold at a flat $20 price, making it accessible to individual developers and teams. For organizations where architectural integrity matters—teams managing microservices, plugin architectures, or domain-driven designs where layer violations compound into significant problems—the cost justifies itself through prevented rework.
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.
