Best alternative to Burp Suite

Best alternative to Burp Suite for most teams is a self-service API security scanner that requires no agents, SDKs, or code access. You submit a URL and receive a risk score from A to F with prioritized findings. The scanner operates in black-box mode using only read-only methods (GET and HEAD) plus text-only POST for LLM probes, and completes a scan in under a minute.

The scanner covers 12 categories aligned to OWASP API Top 10 (2023) and maps findings to PCI-DSS 4.0 and SOC 2 Type II. It detects authentication bypass and JWT misconfigurations, BOLA and IDOR via sequential ID enumeration, BFLA and privilege escalation attempts, property over-exposure and mass-assignment surfaces, input validation issues such as CORS wildcard usage and dangerous HTTP methods, rate-limit header detection and oversized responses, PII patterns and API key format leaks, HTTPS and HSTS misconfigurations, SSRF indicators in URL-accepting parameters, inventory issues like missing versioning, unsafe consumption surfaces, and LLM-specific adversarial probes across Quick, Standard, and Deep tiers. It also parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution and cross-references spec definitions against runtime findings.

Authenticated scanning is available from Starter tier onward, supporting Bearer, API key, Basic auth, and Cookie credentials. Domain verification via DNS TXT record or HTTP well-known file ensures only the domain owner can scan with credentials, and a strict header allowlist limits forwarded headers to Authorization, X-API-Key, Cookie, and X-Custom-* headers. The scanner enforces a read-only posture: destructive payloads are never sent, private IPs and cloud metadata endpoints are blocked at multiple layers, and customer data is deletable on demand and purged within 30 days of cancellation.

Delivery options include a Web Dashboard for scanning and score trend tracking, a CLI via an npm package with JSON or text output, a GitHub Action for CI/CD gating that fails builds below a score threshold, an MCP Server for AI coding assistants, and a programmatic API for custom integrations. Continuous monitoring in Pro tier provides scheduled rescans every 6 hours, daily, weekly, or monthly, diff detection across scans with email alerts rate-limited to one per hour per API, HMAC-SHA256 signed webhooks with auto-disable after five consecutive failures, and branded compliance PDF exports.

Free tier offers three scans per month and CLI access. Starter at 99 dollars per month supports 15 APIs, monthly scans, dashboard, email alerts, and MCP Server. Pro at 499 dollars per month supports 100 APIs with incremental charges beyond that, continuous monitoring, GitHub Action gates, CI/CD integration, Slack and Teams alerts, compliance reports, and signed webhooks. Enterprise at 2000 dollars per month adds unlimited APIs, custom rules, SSO, audit logs, SLA, and dedicated support. For most teams, this scanner is the best alternative to Burp Suite because it delivers fast, automated risk scoring without the operational overhead of proxy interception and manual testing.
