A CODE EDITOR FOR AGENT WORKFLOWS—WITH KNOWLEDGE BUILT IN

A living knowledge base, built into your code editor.

FiboCode weaves code, docs, and graphs into a living knowledge base inside the editor, then brings that shared context to the Agent CLI you choose—so you and your agents can understand, navigate, and change code together.

Understanding grows with the code.

Why Fibo

Inspired by the Fibonacci spiral.

FiboCode is named after the Fibonacci spiral: a complex system often starts from a tiny pattern, then expands, settles, and connects until it grows into a full codebase.

Every complex system begins with a small pattern.

Information Flow

From understanding to editable source.

FiboCode keeps code, docs, and graphs connected, so understanding stays close to the code you can change:

Explore Codebase Understanding
  • Code remains the source of truth.
  • Docs make behavior and intent readable.
  • Graphs make relationships visible and navigable.
  • Tags carry context across code, docs, and graphs.
Terminal Workflow

Keep your terminal. Bring more context.

Use the Agent CLI you already trust. FiboCode adds workspace-aware file search, symbol context, image paste, and clickable paths directly inside the terminal, so your terminal workflow becomes richer without becoming different.

Using Claude Code or Codex? Install Fibo Skills for the full spec-driven workflow.

  • Search workspace files and insert absolute paths.
  • Look up symbols of open files and insert locations.
  • Paste images so agents get screenshots and error context.
  • Click paths in terminal output to jump back to the editor.
Agent CLI Review

IDE-grade review for any Agent CLI.

Keep your favorite command-line agent. FiboCode adds an IDE-grade review surface on top of its changes: diff, hunk, history, rollback, and quick inspection.

Spiral Evolution

Record how the code evolves—in Markdown.

FiboCode uses Markdown—a format both humans and AI can read and write with ease—to record specs, designs, plans, change explanations, and code analysis. Kept alongside the code, these records form a traceable history of the codebase that agents can carry into the next change.

Explore Markdown knowledge workflows
  • Spec captures acceptance criteria from fuzzy intent.
  • Design and plan turn specs into traceable decisions and tasks.
  • Diff records explain real code changes hunk by hunk.
  • Analysis docs keep file and directory understanding up to date.

Fibo makes code understanding simpler — for humans and agents.
