Core toolkit

A familiar security testing workflow

Arkium keeps the product shape obvious for Burp users while organizing the work around modern Web and API assessments.

  • Proxy

    Intercept and inspect HTTP/WebSocket traffic.

  • Repeater

    Replay, modify, and iterate on requests.

  • Scanner

    Discover vulnerabilities with automated and guided testing.

  • Extensions

    Extend workflows with community and custom plugins.

  • Projects

    Organize findings, sessions, and assessments.

Product workflow

Built by security researchers. Designed for real assessments.

Manual testing stays visible and controllable: inspect every request, replay exact steps, organize projects, automate repeatable checks, and use AI assistance only where it improves the workflow.

Representative Arkium desktop workflow: proxy capture, request/response editing, repeater iterations, scanner findings, and project context in one assessment workspace.

Testing workflow

Manual testing first. Automation when it helps.

Start with the core tools, automate repeatable checks, then use AI assistance for review, summarization, and test ideas without giving up control.

  • Proxy inspection

    Capture HTTP, HTTPS, and WebSocket traffic with precise scope controls and readable request history.

  • Request replay

    Modify, resend, diff, and iterate on requests from a focused Repeater workflow.

  • Automation workflows

    Automate repetitive checks, auth flows, fuzzing runs, and release regressions without hiding the underlying traffic.

  • Project collaboration

    Share sessions, findings, evidence, and review context with pentest and AppSec teams.

  • Extensible architecture

    Connect scanners, notifiers, custom checks, and internal tooling through community and private plugins.

  • AI assistance

    Summarize responses, draft payload ideas, and suggest test cases while keeping the tester in control.

Migration

Why switch from Burp Suite?

Arkium is not framed as a replacement for expertise. It is a modern desktop toolkit built for today’s Web and API assessment workflows.

Arkium vs Burp Suite
  • Modern interface

    A cleaner workspace for proxy traffic, request editing, findings, and project context.

  • Better workflow organization

    Keep captures, repeater sessions, scanner results, evidence, and notes tied to the same assessment.

  • Built-in automation

    Turn repeated checks into reusable workflows without losing visibility into requests and responses.

  • Team collaboration

    Share projects, review findings, and keep AppSec and pentest teams aligned.

  • Extensible architecture

    Add community plugins, private extensions, and internal integrations as your testing process grows.
