tidev

A terminal-based AI coding assistant built in Rust. Tidev reimplements the interaction model of OpenCode with a focus on performance and memory efficiency.

Disclaimer: This project is early in development. The database structure and UI may iterate quickly and produce incompatible changes. Run at your own risk.

Features

• Multi-Provider LLM Support -- Anthropic (Claude), OpenAI Chat Completions, and OpenAI Responses. Configurable presets with fallback providers and models.

• Specialized Sub-Agents -- Six agent roles for delegating tasks: General (default), Explorer (code search), Librarian (documentation), Oracle (architecture review), Designer (UI/UX), and Fixer (fast implementation). Each agent has a tailored system prompt and tool set.

• Built-in Tool Set

  • File operations: read, write, edit, apply_patch
  • Code search: list, glob, grep
  • Shell command execution with permission control
  • Session management: task delegation, todo tracking, question prompts
  • Web integration: search (Exa) and page fetching

• Model Context Protocol (MCP) Support -- Connect to MCP servers via child process or streamable HTTP. MCP tools are automatically discovered and available with namespaced permissions (mcp:<server>:<tool>).

• Git Snapshot & Revert -- Automatically track file changes in the workspace using git. View diff statistics and revert changes when needed.

• Permission System -- Granular tool permissions per session mode (Read, Search, Write, Edit, Execute, Session).

• Usage Statistics -- SQLite-based tracking of token consumption (input, output, cache) and request counts with time-bucket aggregation (hour, day, week, month).

• API Balance Checking -- Query account balances for DeepSeek and SiliconFlow providers directly from the UI.

• Session Persistence -- All conversations are stored in SQLite. Sessions, workspaces, messages, tool events, and reverts survive restarts.

Performance

Significantly lower memory usage and binary size compared to OpenCode:

Experimental: Gateway Mode

A gateway mode is under active development that runs tidev as a persistent server with bot integrations (like OpenClaw):

• Telegram -- Polling-based bot with file attachment support and user allowlist.
• QQ -- Bot integration using the QQ channel API with sandbox mode.

Both platforms can run simultaneously via a shared channel orchestrator. Gateway mode uses a dedicated system prompt and manages separate chat-to-session mappings.

Run with:

tidev gateway

Note: Gateway mode is experimental. Configuration, reliability, and feature coverage are still evolving.

How to Pronounce It?

I'd like to pronounce it as "tide-v", but "ti-dev" should also be fine.

Install from crates.io

1. cargo install tidev
2. Run tidev in your working directory.

Install from Source

1. Ensure the latest Rust stable toolchain is installed. https://rust-lang.org/
2. Clone the repository and cd tidev.
3. cargo install --path .
4. Run tidev in your working directory.

Configuration

• Config file: ~/.config/tidev/config.toml
• Auth file: ~/.local/share/tidev/auth.json
• Session database: ~/.local/share/tidev/sessions.sqlite3

Provider presets in the repository root (presets.toml) are merged with user configuration at runtime.
