Snyk API & Web (formerly Probely) alternatives: 7 tools compared

1. AttackerView

AttackerView is a managed security testing service for web apps: it scans your app from the outside, crawls behind your login, connects findings into attack chains, and runs AI pentests with real exploit tools. Every finding comes with proof.

AttackerView or Snyk API & Web (formerly Probely)?

Snyk API & Web is the better pick if you mainly scan APIs inside a Snyk shop, or want a free DAST plan with a 14-day full trial. AttackerView is the better fit if you want published pricing, attack chains and AI pentests without an Enterprise contract.

2. Aikido Security

Aikido Security is a developer-focused application security platform that covers code (SAST, SCA, secrets), cloud, attack surface (DAST and AI pentesting) and runtime protection in one product.

Pricing

Free plan; Basic €300/mo, Pro €600/mo, Advanced €900/mo for 10 users (European prices; $350, $700, $1,050 in USD) source

Free plan or trial

Yes:free-forever Developer plan: 2 users, 10 repos, 1 domain; no paid-plan trial listed source

AI pentesting

Yes:autonomous agents; scoped pentests from $50, typical assessment about $4,000, continuous testing by quote; Pro and Advanced include monthly credits source

Who should pick it

Aikido is the stronger pick if you want one platform across code, dependencies, cloud and runtime, wired into your IDE and pull requests. AttackerView is the better fit if you want deep testing of the running web app from the outside, with time-boxed AI pentest runs, at a price that does not grow with team size.

3. Astra Security

Astra Security is a compliance-oriented pentest platform that combines a DAST scanner, AI and human-led pentests, and API and cloud scanners, sold per target to teams that need a pentest report for an audit.

Pricing

Per target: DAST from $69/mo ($199/mo for unlimited scans); pentests $2,999 to $9,999+ a year source

Free plan or trial

No free plan listed; one-week DAST trial for $7 source

AI pentesting

Yes:autonomous AI pentest for web apps and APIs, plus human-led pentests source

Who should pick it

Astra is the better pick if an auditor or enterprise customer needs a human-led pentest report and certificate, which AttackerView does not sell. AttackerView is the better fit if you want continuous testing across all your apps on one monthly plan, with time-boxed AI pentest runs, rather than a price per target.

4. Detectify

Detectify is a Swedish DAST and external attack surface management platform whose vulnerability tests come from a crowd of 400+ ethical hackers, built for AppSec and security teams.

AI pentesting

AttackerView is the better fit for a startup that wants authenticated testing, AI pentests and audit evidence at a published monthly price.

5. Intruder

6. Nuclei

Nuclei is ProjectDiscovery's open-source (MIT) vulnerability scanner driven by YAML templates, which your team installs and runs. ProjectDiscovery also sells a hosted Cloud platform and Neo, a separate AI pentesting product.

AttackerView is the right pick if you want testing managed for you: type a URL and get authenticated testing, AI pentests, monitoring and audit evidence without operating anything.

7. Pentest-Tools.com
