🪐 LastBrowser VS Opera One

Local-first & MCP instead of proprietary Aria

Opera One locks users into a closed ecosystem with proprietary Aria AI and telemetry data. LastBrowser focuses on Local-first data sovereignty, the open Model Context Protocol and integrated Windows developer tools.

LastBrowser

Local-first & Local
  • ✓ Local-first: Storage only locally in %APPDATA%.
  • ✓ Model Context Protocol (MCP): Connect external databases and tools via an open standard.
  • ✓ Flexible model choice: Configure available providers or use local Ollama models.
  • ✓ Real ConPTY terminal: PowerShell/CMD right in the sidebar (Ctrl+`).
  • ✓ Multi-account Spaces: Clean partitioning of login sessions.

Opera One

Proprietary & Cloud-bound
  • ✕ Closed source: Proprietary browser with unclear data flow to corporate servers.
  • ✕ Proprietary Aria AI: Limited model choice with no open tool connection.
  • ✕ No local models: No offline operation via local LLMs (e.g. Ollama).
  • ✕ No terminal: Pure consumer focus with no command-line integration.
  • ✕ Telemetry & sponsoring: Numerous preset ad and partner links.
