Like Claude Code or Gemini CLI — but desktop-native, with deep control over temperature, thinking levels, output tokens, raw SSE diagnostics, and cost analytics. Powered by a Rust backend for lightning-fast orchestration. 12+ LLM providers, 87+ tools, zero telemetry.
Claude Code and Gemini CLI are great. TierBot gives you everything they have — plus the control panels they don't.
Every knob, every diagnostic, every byte — visible and controllable.
Adjust temperature, thinking level (minimal/low/medium/high/max), and max output tokens per conversation. Model-aware validation — unsupported levels auto-reset.
Pick Flex (−50% cost), Standard, or Priority (+speed) per request. The only AI app that lets you control API service tiers directly.
Custom system prompts per workspace profile. Full tools schema control — enable/disable specific tools. Backend-resolved in Rust.
View every raw SSE chunk received from the LLM. Full request payload sent to the API. Response headers. HTTP status codes, TTFB, bytes received — per turn.
Time to first token, tokens per second, and total generation time — measured from the actual API call, not the UI loop. Generation phase isolated from prefill latency.
Per-turn cost breakdown (input/cache/output). Cross-chat spend dashboard with daily bar charts, provider/model breakdown, and 14-day sparklines.
Hybrid calibration with EMA ratio. Parallel map-reduce summarization (3 batches concurrent). Context pressure indicators. Never hit context_length_exceeded again.
Under 700MB RAM for 40M+ token conversations. Lazy-loaded message data. Lightweight tree snapshots. Delta saves. Content-visibility for off-screen messages.
Full message tree with branching, sibling navigation, and edit history. Overwrite or branch from any message. Visual flowchart with spine & lanes layout.
Gemini, OpenAI, xAI Grok, Moonshot Kimi, NeuralWatt, OpenCode, Ollama, OpenRouter, Fireworks, Together, Command Code. Add new providers with one YAML file — zero code changes.
Real MCP client (rmcp) with stdio + HTTP transports. 19 quick presets. External SKILL.md discovery from .agents/, .claude/, .github/. Agent Skills are cache-safe.
File I/O, semantic search, command execution, Python execution, git operations, HTTP requests, YouTube search, web fetch, task management, sub-agent spawning, and more.
Access TierBot from your phone browser. Embedded HTTP+WebSocket server. QR code pairing, PIN auth, real-time streaming sync across devices. Auto-start on launch.
AES-256-GCM encrypted API key storage. File-based user settings (survives DB reset). Zero telemetry. No data leaves your machine except API calls you initiate.
Work on remote servers via SSH. Auto-discovery of ~/.ssh/config hosts. Port forwarding. Remote command audit log. All file tools work transparently over SSH.
Pay once for the app. Bring your own API keys. No subscriptions, no per-token markup.

💡 BYOK: TierBot uses your own API keys. You pay the LLM provider directly — no markup, no middleman. Service tier selection (Flex −50%, Priority +speed) helps you optimize costs on supported providers.
Available for macOS Apple Silicon. Windows and Linux coming soon.

TierBot is an indie app, not yet enrolled in Apple's $99/year Developer Program for code signing. macOS flags unsigned apps downloaded from the browser as "damaged" — this is a Gatekeeper restriction, not an actual problem with the file.
1. Open the downloaded TierBot_0.3.0-beta.dmg and drag TierBot to your Applications folder.
2. Open Terminal (⌘+Space → type "Terminal") and run:
xattr -cr /Applications/TierBot.app
3. Open TierBot from Applications or Launchpad. That's it!
Alternative: Right-click TierBot in Applications → "Open" → click "Open" in the dialog. You only need to do this once.
