DeepScan catches runtime errors in JavaScript, TypeScript, React, and Vue.js beyond what linters find. See its pricing, GitHub integration, and features.
DeepScan is a static analysis tool focused specifically on JavaScript and TypeScript code quality, built by a South Korea-based team registered under a formal business license (Business Registration No. 120-87-15657). Rather than relying solely on syntax pattern matching like a typical linter, DeepScan performs semantic analysis and data-flow examination to trace how values move through code and flag issues that would only otherwise surface at runtime.
The tool supports JavaScript, TypeScript, Node.js, React, Vue.js, and Astro codebases, and is used by organizations including Samsung SDS and CureApp according to its marketing materials. It positions itself as a complement to, rather than a replacement for, traditional linters like ESLint.
DeepScan's core strength is semantic, data-flow-aware analysis that can catch bugs such as unreachable code, incorrect variable usage, and other logic errors that syntax-only linters typically miss. It integrates directly with GitHub, automatically syncing with repositories and reviewing pull requests as part of a team's existing workflow.
The platform tracks issues and historical code quality trends over time through team dashboards, and offers plugins for SonarQube, common CI/CD servers, and editors including VS Code and IntelliJ, letting developers see flagged issues without leaving their normal tools.
DeepScan is free for unlimited public repositories, including JavaScript and TypeScript analysis, automatic GitHub syncing, a code quality grading system, and 3 months of historical trend data, making it a no-cost option for open-source projects.
For private repositories, paid plans start at $9 per seat per month for one private project on GitHub.com, rising to $19 per seat per month for up to 5 private projects, both with a 14-day free trial and roughly a 16% discount for annual billing. Organizations that host code on their own infrastructure can get custom Enterprise pricing with self-hosted deployment.
Yes, for unlimited public repositories. Private repositories require a paid plan starting at $9 per seat per month.
DeepScan performs semantic and data-flow analysis to catch runtime-level bugs, while ESLint focuses more on syntax and style pattern rules; many teams use both together.
Yes, it automatically syncs with GitHub repositories and can review pull requests as part of the workflow.
Yes, through its Enterprise plan, which supports running the analysis on an organization's own servers.
