ProtoPeek v0.6.1 brings protocol inspection, network evidence and resumable downloads into six desktop workspaces: Home, Inspect, Network, Publish, Files and Settings.

What changed

  • Inspect services: gRPC reflection and proto/protoset workflows, improved typed templates and schema paths, saved HTTP requests with fuzzy search, WebSocket/SSE sessions and Cap’n Proto bootstrap RPC over TCP or verified TLS.
  • Understand the network: single-host TCP port scans, authorized private discovery, optional Nmap scans, Windows IPv4/IPv6 ICMP paths, optional country/ASN attribution and bounded packet metadata from PCAP/PCAPNG or installed dumpcap.
  • See this device: native Linux/Windows socket ownership, explicit traffic monitoring and unsent handoffs into protocol and publishing tools.
  • Use installed network tools: Tailscale peers, diagnostics and reviewed CLI actions; Cloudflare Tunnel host/config inspection, version checks and guarded service controls.
  • Download locally: Windows x64 now includes pinned aria2 1.37.0 inside the executable. Destination browsing, queue/history persistence, filename conflict handling, progress, pause/resume and restart recovery are improved.
  • Keep the desktop practical: left workspace navigation, vertical protocol/settings tabs, independent scrolling, local draft/preferences storage and visible loading, cancellation and save failures.
  • Check websites: explicit TLS/header evidence, five fixed HEAD path checks and separate historical certificate-name lookup. Results preserve uncertainty rather than assigning a security score.

Release reliability

This release supersedes the v0.6.0 candidate. It uses Go 1.26.8, including the upstream fix for the Windows runtime crash found during CI. Stable and edge publishers now select their exact intended tags, and the source-archive contract reads the complete listing.

Windows installation fixed

The documented pipeline now works in Windows PowerShell 5.1 and PowerShell 7, including from System32. It fixes architecture detection, successful native stderr during binary checks and empty ownership markers. Installation is per user and includes a Start-menu shortcut with a stable local browser origin.

Unix:

Both installers verify the selected archive against checksums.txt. Archives provide protopeek and pp, manuals and third-party notices. The separate aria2 source companion accompanies the Windows x64 bundle.

Capabilities and requirements

  • Closing the browser leaves downloads running while ProtoPeek stays open. Restarting the server restores recoverable jobs for explicit resume. Up to 16 connections is a limit, not a guaranteed 16× speed increase.
  • Linux, macOS, Windows ARM64 and Windows 32-bit use installed aria2. Configured and PATH engines take priority over the Windows x64 bundle. The bundled upstream Windows engine does not support TLS 1.3-only servers.
  • Nmap, dumpcap, Tailscale and cloudflared integrations require those local tools and their OS permissions. Cap’n Proto source compilation requires capnp; compiled schemas work without it.
  • macOS native hop probes and socket/counter activity remain unsupported. Packet inspection is bounded metadata, not full Wireshark decoding or decryption. Country/ASN labels do not prove a datacenter, inter-router latency or return path.
  • Headscale, NetBird, integrated sign-in/elevation, deeper packet decoding, HTTP environment profiles and Cloudflare configuration writes remain roadmap work.

Verification

760 frontend tests, Go tests across Windows/Linux/macOS, installer checks across platforms, container smoke, generated asset checks and archive/checksum/SBOM contracts are part of the release gates. Local static checks also pass. Browser acceptance covers successful requests, failures, cancellation and persistence; native live capture and automated file-picker acceptance remain limited by installed tools and Chrome extension permissions on the review host.
