What is Deepscan?

Editorial review

DeepScan is a static code analysis tool designed to improve JavaScript and TypeScript code quality. It goes beyond traditional linting tools like ESLint by employing data-flow analysis to understand the execution flow of your program, accurately identifying potential errors and code issues without requiring the code to be run. This allows developers to catch mistakes early in the development cycle, before they are committed. The platform integrates seamlessly with GitHub, continuously analyzing team projects as commits are pushed. It provides an overall quality status for teams, tracks issues over time even with code changes, and assigns a simple 'Poor', 'Normal', or 'Good' grade to projects to motivate maintaining clean code. DeepScan supports modern web technologies including the latest ECMAScript specifications, React, Vue.js, and Astro, making it suitable for individual developers and teams working on contemporary web applications. DeepScan is ideal for development teams and individual developers who want to maintain high code quality, reduce bugs, and ensure best practices are followed in their JavaScript and TypeScript projects. Its continuous analysis and grading system provide ongoing insights into project health, increasing confidence before code deployment.

Is Deepscan worth the price?

75/100

Deepscan's pricing is fair, offering a generous Free tier for public projects and individual developers.

The Lite and Starter plans at $9 and $19 per seat/month respectively are competitive for small teams needing private project analysis. It's best for individual developers and small to medium-sized teams focused on JavaScript/TypeScript quality.

Hidden Costs & Gotchas

Per-seat pricing can add up for larger teams.

Enterprise plan requires custom quote, potentially high.

No annual discount mentioned, monthly billing only.

How Deepscan Compares to Competitors

Compared to SonarCloud, which offers a free tier for open-source and then charges based on lines of code, Deepscan's per-seat model for private projects at $9-$19 is a clear alternative. While SonarCloud can scale more linearly with code size, Deepscan's fixed per-seat cost might be more predictable for teams with stable sizes. Deepscan's focus on JavaScript/TypeScript is also more niche than SonarCloud's broader language support.

How Deepscan's pricing compares

At $9/mo, Deepscan is the most affordable of its 4 direct competitors.
