Burp Suite has been a staple of web application security testing for years. But as APIs become the primary attack surface for modern products, many security engineers and development teams are looking for tools that go further — offering automated OWASP API Top 10 coverage, role-aware testing, OpenAPI-native scanning, and seamless CI/CD integration. This guide covers the top 10 Burp Suite alternatives worth evaluating in 2026.

This article was created with AI assistance and reviewed by the DastPilot team.

Quick Comparison

1. DastPilot — Best for Role-Aware API DAST

DastPilot is purpose-built for automated API security testing. It reads your OpenAPI or Swagger specification and fires real attack payloads against your live API — covering every category in the OWASP API Security Top 10 without manual configuration.

What sets DastPilot apart from every other tool on this list is role-aware security testing. Most scanners fire requests as a single anonymous or authenticated user. DastPilot understands that modern APIs serve multiple user roles — admin, customer, partner, read-only — and tests authorization boundaries between them. This is how it catches BOLA (Broken Object Level Authorization) and BFLA (Broken Function Level Authorization) that single-user scanners miss entirely.

What makes role-aware testing different

Consider a typical e-commerce API. An admin can view all orders; a customer can only view their own. A standard scanner logs in as one user and checks if the endpoint returns data. DastPilot logs in as a customer, then attempts to access another customer's order using the admin's resource IDs — and flags it when the API incorrectly allows it. This cross-role, cross-resource testing is the only reliable way to catch BOLA at scale.

Key features

• Full OWASP API Top 10 coverage — all 10 categories, every scan
• Role-aware BOLA and BFLA detection across multiple user contexts
• SQL, NoSQL, SSTI, and command injection fuzzing based on spec field types
• JWT tampering, expired token acceptance, and broken auth testing
• Mass assignment and sensitive data exposure detection
• OpenAPI 3.x and Swagger 2.0 native — no manual endpoint configuration
• Automated scheduled scanning with CI/CD integration
• Detailed findings with exact payloads, CVSS scores, and remediation guidance
• Finding lifecycle tracking — opened, fixed, and reopened across scan runs

Pricing

$2.00 per API definition per month. No tiers, no feature gating, no contracts. 30-day free trial with no credit card required. Built for startups and growing teams who need enterprise-grade coverage without enterprise-grade pricing.

Best for

Engineering teams and security engineers who ship APIs and need automated, role-aware DAST that runs in CI/CD without manual setup. Especially strong for teams using OpenAPI specifications as their source of truth.

2. OWASP ZAP — Best Free Open-Source Option

OWASP ZAP (Zed Attack Proxy) is the most widely used free security scanner in the world. Maintained by the OWASP Foundation, it supports both manual and automated testing with an intercepting proxy, active/passive scanning, and a rich plugin ecosystem.

ZAP is excellent for learning, research, and teams with budget constraints. However, it is primarily a web application scanner — API-specific coverage requires additional configuration, and role-aware testing is entirely manual. For teams that need automated OWASP API Top 10 coverage out of the box, ZAP requires significant setup work.

Key features

• Active and passive scanning for web vulnerabilities
• Intercepting proxy for manual request manipulation
• OpenAPI support via plugin
• CI/CD integration through Docker and API
• Extensive scripting support (ZEST, Python, JavaScript)

Best for

Security researchers, students, and teams with tight budgets who are comfortable with manual configuration and don't need automated role-aware API testing.

3. Akto — Best for Traffic-Based API Discovery

Akto is an API security platform that automatically discovers APIs by monitoring network traffic, then tests them for OWASP API Top 10 vulnerabilities. Its traffic-based discovery is particularly useful for organizations with large, undocumented API surfaces.

Akto integrates with CI/CD pipelines and provides risk scoring. It is strong on API discovery and continuous monitoring, though role-aware testing depth is more limited compared to spec-driven approaches.

Best for

Teams with large, complex API estates who need automated discovery alongside security testing, particularly in staging and production environments.

4. Acunetix — Best for Web Application + API Combined Scanning

Acunetix is a commercial scanner known for speed, accuracy, and proof-based scanning that reduces false positives. It covers both web applications and APIs, making it a strong choice for organizations that need to test traditional web apps alongside REST APIs.

Acunetix supports OpenAPI, Swagger, and GraphQL. Its proof-based approach verifies vulnerabilities before reporting them, which reduces noise. However, it is primarily a web scanner with API support added on — not an API-first tool — and role-aware testing is not a native capability.

Best for

Enterprise security teams that need to scan both web applications and APIs from a single platform, with strong compliance reporting requirements.

5. Invicti (Netsparker) — Best for Enterprise Automation at Scale

Invicti, formerly Netsparker, is an enterprise-grade web application security scanner built for large-scale automation. Its proof-based scanning verifies vulnerabilities automatically, and it integrates deeply with enterprise CI/CD and ticketing systems.

Invicti is well-suited for large organizations with hundreds of web applications and APIs to scan. The pricing reflects this — it is one of the more expensive options on this list and is primarily designed for enterprise security programs rather than startup or mid-market teams.

Best for

Large enterprises with mature security programs that need scalable, automated scanning across many applications with deep SDLC integration.

6. Astra Pentest — Best for Compliance-Driven Teams

Astra Pentest combines automated scanning with manual security review, producing reports suitable for compliance audits (SOC 2, ISO 27001, GDPR, PCI-DSS). It covers both web applications and APIs, and its dashboard makes it easy to track remediation progress.

The combination of automation and human review adds depth, but also adds turnaround time. For teams that need a compliance artifact alongside their security testing, Astra is a strong option.

Best for

Startups and mid-market companies preparing for compliance certifications who need both automated scanning and a human-reviewed pentest report.

7. Detectify — Best for External Attack Surface Monitoring

Detectify is a cloud-based external attack surface management platform that continuously monitors web applications and APIs for misconfigurations and vulnerabilities. Its modules are built and updated by a community of ethical hackers, giving it fast coverage of newly discovered vulnerability patterns.

Detectify is strong for external surface monitoring but does not test internal APIs or provide the depth of role-aware testing that API-first tools offer.

Best for

Teams that want continuous external monitoring of their public-facing attack surface with minimal setup and fast updates for new vulnerability patterns.

8. Qualys WAS — Best for Enterprise Asset Management Integration

Qualys Web Application Scanning is part of the broader Qualys Cloud Platform, making it a natural fit for organizations already using Qualys for vulnerability management. It provides cloud-based scanning at scale with strong compliance reporting.

Qualys WAS is primarily a web application scanner. API coverage exists but is not its primary strength, and the platform can be complex to configure for teams new to the Qualys ecosystem.

Best for

Large enterprises already invested in the Qualys platform who want to extend their existing vulnerability management program to web applications and APIs.

9. IBM AppScan — Best for DAST + SAST Combined

IBM AppScan is an enterprise application security platform that combines DAST, SAST, and IAST capabilities. It can test both source code and running applications, providing coverage across the full SDLC. AppScan is particularly strong in regulated industries like finance and government.

The breadth of AppScan comes with complexity — setup and tuning require significant investment, and the pricing is enterprise-tier. For teams that only need API DAST, it is likely more than required.

Best for

Large regulated enterprises that need a unified DAST + SAST platform with deep compliance policy controls and government-grade security requirements.

10. Nessus — Best for Infrastructure + Network Vulnerability Scanning

Nessus by Tenable is one of the most widely deployed vulnerability scanners in the world, covering operating systems, networks, databases, and applications. It is not an API security tool — it does not test OWASP API Top 10 vulnerabilities or understand OpenAPI specifications — but it is included here because many teams use it as part of a broader security program alongside a dedicated API scanner.

Best for

Infrastructure and network security teams that need broad vulnerability coverage across systems, servers, and databases. Pair with a dedicated API DAST tool for application-layer coverage.

How to Choose the Right Burp Suite Alternative

Start with your primary use case

Burp Suite is a manual web application testing tool. If you are replacing it, ask what you actually need: automated scanning, API-specific coverage, CI/CD integration, compliance reporting, or external surface monitoring. Different tools excel at different things.

Prioritize API-first tools if APIs are your primary surface

Most tools on this list started as web application scanners and added API support later. If your primary attack surface is REST APIs defined by OpenAPI specifications, choose a tool built for that from the ground up. DastPilot, Akto, and Astra are the strongest API-first options.

Require role-aware testing for authorization coverage

BOLA and BFLA are the top two categories in the OWASP API Security Top 10 — and they are almost impossible to detect without testing across multiple user roles. If your API serves different user types with different permissions, role-aware testing is not optional. DastPilot is currently the only tool on this list with role-aware testing built in as a first-class capability.

Evaluate CI/CD fit before pricing

A scanner that does not fit your pipeline will not get used. Prioritize tools with documented CI/CD integration for your stack and test the integration before committing to a contract.

Match pricing to team size

Enterprise-tier tools like Invicti, IBM AppScan, and Qualys WAS are priced for large security programs. Startups and growing teams will find better value in per-API pricing models (DastPilot) or freemium options (OWASP ZAP, Akto).

Final Thoughts

Burp Suite remains a valuable tool for manual web application testing and security research. But for teams that need automated, continuous API security testing — especially with role-aware coverage across multiple user contexts — it is not the right fit.

The tools above each serve different needs. For teams shipping APIs with OpenAPI specifications and needing automated OWASP API Top 10 coverage with role-aware BOLA and BFLA detection, DastPilot is the strongest purpose-built option. For teams on a budget, OWASP ZAP provides a solid free foundation. For compliance-driven teams, Astra Pentest adds the human review layer that audit reports require.

The right choice depends on your team size, API architecture, compliance requirements, and how deeply security needs to integrate with your delivery pipeline.
