ByteRover CLI

Interactive REPL CLI for AI-powered context memory

ByteRover CLI (brv) gives AI coding agents persistent, structured memory. It lets developers curate project knowledge into a context tree, sync it to the cloud, and share it across tools and teammates.

Run brv in any project directory to start an interactive REPL powered by your choice of LLM. The agent understands your codebase through an agentic map, can read and write files, execute code, and store knowledge for future sessions.

Key Features:

• 🖥️ Interactive TUI with REPL interface (React/Ink)
• 🧠 Context tree and knowledge storage management
• 🔀 Git-like version control for the context tree (branch, commit, merge, push/pull)
• 🤖 18 LLM providers (Anthropic, OpenAI, Google, Groq, Mistral, xAI, and more)
• 🛠️ 24 built-in agent tools (code exec, file ops, knowledge search, memory management)
• 🔄 Cloud sync with push/pull
• 👀 Review workflow for curate operations (approve/reject pending changes)
• 🔌 MCP (Model Context Protocol) integration
• 📦 Hub and connectors ecosystem for skills and bundles
• 🤝 Works with 22+ AI coding agents (Cursor, Claude Code, Windsurf, Cline, and more)
• 🏢 Enterprise proxy support

All benchmarks are run using the production byterover-cli codebase in this repository - no separate research prototype.

We evaluate on two long-term conversational memory benchmarks:

• LoCoMo - ultra-long conversations (~20K tokens, 35 sessions) testing single-hop, multi-hop, temporal, and open-domain retrieval.
• LongMemEval-S - large-scale benchmark (23,867 docs, ~48 sessions per question) testing 6 memory abilities including knowledge update, temporal reasoning, and multi-session synthesis.

LoCoMo - 96.1% overall accuracy (1,982 questions, 272 docs).

LongMemEval-S - 92.8% overall accuracy (500 questions, 23,867 docs).

All metrics are LLM-as-Judge accuracy (%). See the paper, or self-hosted PDF for full details.

No Node.js required - everything is bundled.

curl -fsSL https://byterover.dev/install.sh | sh

Supported platforms: macOS ARM64, macOS x64 (Intel), Linux x64, Linux ARM64.

Requires Node.js >= 20.

npm install -g byterover-cli

brv --version

cd your/project
brv

The REPL auto-configures on first run - no setup needed. Type / to discover all available commands:

/curate "Auth uses JWT with 24h expiry" @src/middleware/auth.ts
/query How is authentication implemented?

The web UI supports a local-first development flow for the shared component library.

npm run dev:ui uses the git submodule at packages/byterover-packages/ui so edits to shared UI components hot-reload immediately in Vite.

# Clone with submodules, or initialize them after clone
git clone --recurse-submodules <repo-url>
# or
git submodule update --init --recursive

# Install dependencies
npm ci

# Start or restart the daemon
./bin/dev.js restart

# Start the web UI in local development mode
npm run dev:ui

Notes:

• Edit shared components in packages/byterover-packages/ui/src.
• npm run dev:ui uses the submodule source.
• npm run build:ui uses the installed package path.
• If /api/ui/config or transport bootstrap fails, restart the Vite dev server after restarting the daemon.

ByteRover Cloud is a hosted platform for teams to sync, share, and manage context knowledge across projects and machines. Everything works locally by default - Cloud adds collaboration and persistence without changing your workflow.

Sign in with your ByteRover account via /login (TUI) or an API key (brv login) to get started.

• 🔄 Team context sync — push and pull shared knowledge across teammates
• 📂 Shared spaces — organize context across multiple projects and teams
• 💻 Multi-machine access — sync your context tree across devices with cloud backup
• 🧠 Built-in hosted LLM — start immediately with limited free usage
• 👥 Team management — manage members, spaces, and permissions via the web app
• 📊 Usage analytics — track seat allocation and monthly credit consumption
• 🔒 SOC 2 Type II certified infrastructure with privacy mode

Vocabulary

• Worktree link — a subdirectory pointer to a parent project (brv worktree)
• Source — a read-only reference to another project's knowledge (brv source)
• Origin — where an indexed search result came from (local vs shared)

ByteRover can run from a linked subdirectory without creating a nested .brv/.

• projectRoot: the directory that owns .brv/config.json
• worktreeRoot: the linked worktree directory, or projectRoot when unlinked
• clientCwd: the shell cwd where you ran brv

When you run brv query or brv curate from a linked worktree, implicit defaults use worktreeRoot so scope stays stable even if clientCwd drifts deeper into the package. Explicit relative paths that you pass yourself, such as brv curate -f ./src/auth.ts, still resolve from clientCwd to match normal shell behavior.

Use brv worktree add from the project root to register a subdirectory (or sibling) as a worktree. This creates a .brv pointer file in the target directory that redirects to the parent project — the same pattern git uses for git worktree. Use brv worktree remove to unregister, and brv worktree list to inspect. To search another project's knowledge from here, use brv source add <path> (with brv source list / brv source remove to inspect or detach).
