Local web firewall and host switcher

Control web access, review local traffic logs, and test staging hosts on iPhone and iPad.

TraceWall is a local HTTP and HTTPS web traffic control app for iOS. Use allowlist or blocklist rules, inspect recent allow/block decisions, and route a domain to a specific IP address for development, staging, migration, and troubleshooting workflows.

Firewall modesAllowlist or blocklist

Choose whether web traffic is open by default with blocked exceptions, or closed by default with allowed exceptions.

Developer workflowHost switcher for staging

Map a domain to a specific upstream IP address to test deployments before public DNS changes are live.

Local visibilityClear allow/block timeline

Review recent local decisions and create rules from log entries without decrypting HTTPS page content.

Core features

Firewall rules, local logs, and controlled host routing

Blocklist mode

Allow supported web traffic by default and block only domains, IP addresses, or ports added to your rules.

Allowlist mode

Block supported web traffic by default and allow only trusted destinations you explicitly approve.

Rule actions from logs

Tap a log entry to quickly allow or block a domain, IP address, or port from a real traffic decision.

Host switcher

Route a domain to a selected IP address for staging, QA, migration, CDN, or origin-server testing.

Import and export

Back up or move firewall rules, host mappings, and settings as JSON using user-controlled import/export.

Local-first privacy

Rules and logs are stored locally. HTTPS content is not decrypted, and no TraceWall account is required.

Important technical notes

  • TraceWall uses the iOS VPN configuration system for local on-device traffic control.
  • The app is designed for supported HTTP and HTTPS web traffic control.
  • HTTPS page content is not decrypted or inspected.
  • Host switcher behavior depends on the target domain, upstream server, TLS/SNI configuration, CDN setup, and server configuration.
  • TraceWall is a local web firewall and developer testing utility, not a remote anonymity VPN service.
