Peeknext

Peeknext is a fast, native text and code editor for macOS, built around low-latency editing, large-file performance, and local workflows.

Built on a native C++ editing core, Peeknext stays responsive when working with large source files, logs, and documents containing millions of lines. It includes multi-cursor editing, split views, synchronized document views, project-wide search, context-aware autocomplete, syntax highlighting, and customizable keybindings.

Peeknext is fully scriptable with Python, allowing users to create custom editor commands and automate repetitive tasks. Inline commands support shell execution, Python evaluation, and AI assistance directly within the editor.

Optional local AI features provide code completion and inline chat through Ollama. Peeknext also works alongside external coding agents such as Claude Code and Codex, automatically reloading files modified outside the editor.

Peeknext works entirely offline, requires no account, and includes no telemetry, tracking, or background downloads.

Available for macOS on Apple Silicon. Free for non-commercial use, with licenses available for professional and business use.
