Amazon CodeWhisperer
A free AI coding assistant by Amazon that generates code suggestions and scans for vulnerabilities inside your IDE.
Tool overview
When to consider it: CodeWhisperer is a strong free option for individual developers who want always-on code completion with built-in security scanning – especially if you’re already in the AWS ecosystem. However, if you need deep project-level context awareness or offline usage, you may find it limited.
What it does: Right inside VS Code or JetBrains, it offers full-line and full-function suggestions based on comments and existing code, covering 15 languages. It’s completely free with no usage caps, and includes 50 free security scans per month that flag vulnerabilities like OWASP violations or weak cryptography patterns. Setup takes a few minutes – just install the AWS Toolkit and sign in with an AWS Builder ID (no credit card required). It also powers command-line completions (formerly Fig).
Cost and fit: Free for individual use (official statement); no enterprise pricing info was found in the evidence. Ideal for students, solo devs, and cost-conscious programmers comfortable with cloud-based assistance. Less suitable for teams needing self-hosted models or organizations that require advanced admin controls.
