What DeepScan does
DeepScan is a Seoul, South Korea-based developer-tools company founded in March 2017 that provides static analysis for JavaScript and TypeScript code. Its core engine uses semantic data-flow analysis and control-flow graph (CFG) analysis rather than AST pattern matching, enabling it to detect runtime errors and code quality issues that conventional linters like ESLint miss. The company supports JavaScript, TypeScript, JSX, TSX, Vue, Astro, and ES6 modules, with a React-specific rule set and a project grading system benchmarked against ~150–200 open-source GitHub projects.
The product portfolio consists of a cloud SaaS (DeepScan) that integrates with GitHub via OAuth and webhooks to perform continuous analysis and pull-request status checks, plus a DeepScan Enterprise suite that packages editor plugins (VS Code, IntelliJ), a SonarQube plugin, and a CLI tool for on-premises analysis behind firewalls. Distribution is hybrid: product-led growth through GitHub OAuth, VS Code Marketplace, and the JetBrains plugin repository, combined with a direct enterprise sales motion for DeepScan Enterprise. The pricing model is freemium (free tier with one private project), monthly SaaS subscriptions (Lite and above), and enterprise licensing on multi-year contracts; pricing is not publicly disclosed.
The company operates as a small, privately held, bootstrapped team of approximately 12 named members in Seoul (Business Registration No. 120-87-15657), with no disclosed venture funding, acquisitions, or parent company. Named customers include CureApp, Samsung SDS, and Jooble alongside several open-source projects (SortableJS, react-async, D2Admin, Seneca, egjs-flicking). The business has maintained a continuous monthly release cadence from 2017 through June 2026 (version 1.71.0) and reports 2,421 days since the last operational incident, indicating long-term product stewardship and operational reliability.

DeepScan product offering
Product offeringCore offering
DeepScan is a cloud-based static analysis platform that inspects JavaScript and TypeScript source code using semantic data-flow and control-flow graph analysis to detect runtime errors and code quality issues that conventional AST-based linters miss. It connects to GitHub repositories via OAuth, performs continuous analysis through webhooks, posts pull-request status checks, and presents multi-level (High/Medium/Low) issue reports with project grades calibrated against open-source benchmarks. The DeepScan Enterprise package additionally provides on-premises deployment (VS Code embedded, IntelliJ, SonarQube, and CLI) so organizations can analyze code behind firewalls without transmitting source to DeepScan servers.
Product overview
DeepScan is a static analysis platform for JavaScript and TypeScript code, comprising a cloud SaaS product (DeepScan) and an enterprise self-hosted suite (DeepScan Enterprise). The cloud product connects to GitHub repositories via OAuth, performs continuous code analysis through webhook-based automation, and reports issues with impact levels and project grades via a web dashboard and GitHub pull request status checks. DeepScan Enterprise is a separate package enabling analysis behind a firewall without transmitting code to DeepScan servers, and includes four integrated tools: the Visual Studio Code Extension (with both open-source and embedded Enterprise modes), the IntelliJ Plugin, the SonarQube Plugin (for integration into SonarQube quality management workflows), and the CLI Tool (for CI/CD pipeline integration). The platform also offers a Demo for instant code inspection and an Open Source Report aggregating analysis results across 200 GitHub projects.

DeepScan competitors and assessment
Company assessmentBroad incumbents
- Checkmarx: Checkmarx CxSAST is an established enterprise SAST platform with multi-language static analysis. It competes for the same enterprise security and code-quality budget as DeepScan, particularly where buyers want a single vendor across the SDLC.
- Veracode: Veracode is a broad application security testing platform with SAST, SCA, and DAST. It competes with DeepScan in the static analysis category but at enterprise/CISO level, with much larger scope across languages and security testing modalities.
- GitHub CodeQL: GitHub's native CodeQL performs semantic code analysis and is integrated directly into the GitHub platform where DeepScan already plugs in. As a built-in capability of the primary distribution channel, CodeQL represents both a competitor and a channel risk for DeepScan.
Direct peers
- ESLint: ESLint is the dominant open-source JavaScript/TypeScript linter that DeepScan explicitly differentiates against. It is free, ubiquitous, and the de facto baseline against which DeepScan positions its value (detecting issues linters cannot). It is DeepScan's primary reference competitor.
- Sonar (SonarQube / SonarCloud): Sonar's SonarQube and SonarCloud are the closest direct competitor to DeepScan — code quality and static analysis platforms with broad language support. DeepScan even integrates into SonarQube via a dedicated Enterprise plugin, confirming overlap in use case (JavaScript/TypeScript quality) and target buyer (engineering teams).
- Codacy: Codacy provides automated code review and quality analysis with GitHub/GitLab/Bitbucket integration. It targets the same developer-team buyer as DeepScan with a multi-language platform and direct overlap in code-review automation and quality dashboards.
- Semgrep: Semgrep offers open-source and commercial static analysis with semantic rule matching across many languages. It competes for the same developer-tooling budget with stronger open-source community traction and enterprise adoption in security-sensitive buyers.
- Snyk Code: Snyk Code provides SAST and AI-powered static analysis inside the Snyk developer security platform. It directly competes for the same buyer (engineering teams buying code quality + security tooling) with broader language coverage and significantly larger commercial footprint.
Emerging players
- Socket (socket.dev): Socket analyzes open-source dependencies and code for security and quality issues from a developer-tooling perspective. While its primary lens is supply-chain rather than first-party code analysis, it competes for overlapping developer-tool budget and security-conscious buyer attention.
- DeepCode (now part of Snyk): DeepCode was an AI-based code review tool focused on JavaScript/TypeScript and other languages, eventually acquired by Snyk. It is a historically comparable point-product in static analysis that validates both the opportunity and the consolidation pressure DeepScan faces.
