SONARQUBE ALTERNATIVE
A SonarQube alternative focused on exploitable security bugs
SonarQube is an established platform for code quality and static analysis. If what you need is to find the vulnerabilities an attacker could actually use, Nurbak reasons over your code with its own AI model, checks dependencies and git history, and sends each fix as a pull request.
Create account and connect GitHubWe never store your code. We only write when you ask for a fix PR.
Security, not lint
Nurbak doesn't score style or maintainability. Every finding is a security issue with file, line and a plain-language explanation of the risk.
Logic flaws found by reasoning
IDOR, broken authorization, SSRF and JWT issues depend on how your app works. Our model follows the data across files to find them.
Dependencies, secrets and CI included
Dependency CVEs from OSV, secrets in the whole git history and GitHub Actions, Docker, Terraform and Kubernetes misconfigurations, in the same scan.
Fix PRs with a regression test
One click opens a pull request with the fix and a security test that keeps the bug from coming back.
SonarQube vs Nurbak at a glance
A factual summary based on the information SonarQube publishes on its website (September 2026). Products and plans change, so check sonarsource.com for current details.
| Aspect | SonarQube | Nurbak |
|---|---|---|
| Main focus | Code quality and code security: bugs, vulnerabilities and security hotspots | Exploitable security vulnerabilities in your repo |
| How analysis works | Static analysis with quality and security rules, including taint analysis | Nurbak's own AI model reasons over the code across files |
| Where the code is analyzed | SonarQube Cloud (SaaS) or SonarQube Server (self-managed) | Nurbak's self-hosted model on ephemeral infrastructure, not sent to OpenAI or Anthropic |
| Dependencies (SCA) | Available with the Advanced Security add-on | Included: known CVEs from the OSV database |
| Secrets | Secret detection in the IDE and in the CI/CD pipeline | Secrets in the code and in the full git history |
| Infrastructure as code | Terraform, CloudFormation, Kubernetes, ARM and Ansible | GitHub Actions, Docker, Terraform and Kubernetes |
| Fixes | AI CodeFix: LLM-generated fix suggestions | One-click pull request with the fix and a security regression test |
| Pricing model | Based on lines of code analyzed, with a free tier and an open-source Community Build. See their site for prices | Per repo: USD 79/month for 1 repo, USD 199/month for up to 5, Enterprise above 5 |
Which one should you choose?
Choose SonarQube if
You want quality gates for the whole team: bugs, maintainability and coding rules across many languages, in the IDE and in CI, with the option to self-manage the server. It is a mature tool for that job.
Choose Nurbak if
Your priority is security: finding exploitable vulnerabilities like IDOR or SSRF, vulnerable dependencies and leaked secrets, and fixing them through pull requests, with simple per-repo pricing.
Use both if
You want to keep SonarQube for code quality and add Nurbak as the security layer. They don't conflict: one looks at how maintainable the code is, the other at how attackable it is.
How to try Nurbak next to SonarQube
Create an account and connect GitHub. Public and private repos both work.
Pick a repo. Nurbak's own model analyzes it on ephemeral infrastructure.

Keep your SonarQube setup as is. Nothing needs to be migrated.
SonarQube alternative FAQ
Is Nurbak a replacement for SonarQube?
Not for everything. SonarQube covers code quality and maintainability, which Nurbak doesn't try to do. Nurbak is an alternative for the security side: exploitable vulnerabilities, dependency CVEs, secrets and misconfigurations, with fixes as pull requests.
Does SonarQube do SAST?
Yes. SonarQube presents itself as a SAST tool and finds vulnerabilities and security hotspots with static analysis. The difference is the approach: Nurbak uses its own AI model to reason about how data moves through your app, which targets flaws like IDOR or broken authorization that depend on business logic. More in AI SAST.
Snyk vs SonarQube vs Checkmarx: where does Nurbak fit?
SonarQube combines code quality and security, Snyk's platform includes Snyk Open Source for dependencies and Snyk Code for SAST, and Checkmarx One is an application security platform built for enterprises. Nurbak is for code-first teams that want one scan on their GitHub repos, AI reasoning over their own code, fixes as pull requests and per-repo pricing. See also our Snyk alternative page.
Where is my code analyzed?
On Nurbak's own self-hosted model, on ephemeral infrastructure. The analysis doesn't send your code to OpenAI or Anthropic, and every step is recorded in a hash-chained audit trail. Only if you ask for a fix pull request and give explicit consent is the fix generated with Claude.
How does pricing compare?
SonarQube prices by lines of code analyzed and offers a free tier and an open-source Community Build (check their site for current prices). Nurbak charges per repo, not per developer: the first scan is free with the 3 most important findings in full and 1 free fix PR, then USD 79/month for 1 repo or USD 199/month for up to 5 repos with daily scans. See pricing.
Do I need to migrate anything from SonarQube?
No. Connect GitHub, choose a repo and run the first scan. You can keep SonarQube running in CI and compare the results. To see which categories Nurbak prioritizes, read our OWASP Top 10 2025 guide.
