Built in Rust. Tested. Workspace-scoped. No excuses.
Full-screen terminal interface built with Ratatui. Chat panel, agent sidebar, approval queue — all keyboard-driven.
All operations are sandboxed to your project workspace. No wandering outside. What happens in the workspace stays in the workspace.
11 modules: file ops, git power tools, code quality, dev workflow, AI power tools, external integrations, UX tools. Every tool you need, built in.
Builder, Planner, Architect, Guardian, Checker, Docs, and Vibe Coder — each with defined identity and behavioral contract.
Aggressive obedience rules tailored per model: CloudStrong, LocalMedium, LocalSmall, Precise, VibeCoder, and TestResearch.
llama3.2 is HARD-LOCKED to TestResearch preset. Cannot be overridden. Blocked from production coding. Test/internet/research only.
Preconfigured servers: filesystem, GitHub, fetch, memory, SQLite, Playwright, Chrome DevTools, Figma, Postman, Google Workspace, and more. Dynamic tool discovery at startup.
Review every change before it lands. Diff view, approve/reject/edit — you stay in control of your codebase.
CLI parsing, provider configs, agent definitions, workspace validation, preset detection, RAG chunker, model discovery, license system, feature gates, MCP — tested and green. Run cargo test yourself.
Major cloud, local self-hosted, Chinese providers, aggregators, and specialty endpoints. Set your API key, pick a provider, go.
3-level text compression (lite/medium/ultra) to slash token usage. Estimate savings before sending. Decompress when needed.
Persistent cross-session memory. Store decisions, conventions, preferences. Recall by query. Never forget what you told it.
Relevance-scored file search. Code structure summarization. Finds the right files for your task without flooding context.
Dependency-graph task planning. Plan execution rounds, dispatch independent tasks in parallel, batch operations.
Reusable prompt templates with {{variable}} substitution. Built-in templates for code review, commits, debugging, testing, docs.
Automatic model tier selection. Simple tasks → fast model. Architecture → heavy model. Save cost without thinking about it.
Red-green-refactor cycle with automatic test/build/lint verification. Never ship without tests again.
Generate C4 architecture diagrams (context, container, component) as Mermaid. Visualize your system from 30,000 feet.
Automated code review: diff analysis, file scanning, security checks. Catch issues before they ship.
Feature/release/hotfix branch workflow with automated merge. Standard git flow, zero friction.
Persistent markdown plans in .fevercode/plans/. Track tasks, mark progress, resume across sessions.
Project overview: file counts, language breakdown, dependency analysis, health checks. Know your codebase at a glance.
BSL 1.1 license, feature gates, Pro/Team/Enterprise tiers. License activation, analytics, audit logs — revenue infrastructure built in.
Small local models (Phi4 1.5B) match top LLMs through iterative document retrieval. Index workspace docs, query with `/mastermind`, get cited answers.
`/discover` queries your provider's `/models` endpoint automatically. No more guessing model names. Works with Ollama, Z.ai, OpenAI, and all 53 providers.
Vague request detected? FeverCode asks 1-3 focused questions, collects answers, and checks readiness before generating a plan. No more guessing user intent.
DarkAero, EgyptianPortal, Matrix, Ocean, Monokai, SolarizedDark, Nord, Dracula, GruvboxDark, RosePine. Switch with `/theme`.
Agent constitution for Ra, Thoth, Ptah, Maat, Anubis, Seshat, and Vibe Coder. Each agent has a defined identity and behavioral contract.
Output truncation, secret redaction, and session logging. Keep token usage lean without losing critical information.
JSONL event log and compact summaries. Resume where you left off with full conversation history preserved.
macOS, Linux, and Windows installers. One command to get FeverCode running — pending first release.
cargo install fevercode and pre-built binaries for Linux, macOS, Windows. One command, zero friction.

Three operating modes. You choose how much autonomy FeverCode gets.
Read-only. FeverCode analyzes your code, answers questions, suggests changes — but touches nothing. Safe as a conversation.
Proposes changes through the approval queue. Every edit, every file operation passes through your review before applying.
Full autonomy within the workspace boundary. FeverCode executes plans, writes code, runs tests — all without waiting for approval.
Regardless of mode, FeverCode never operates outside your project directory. No home directory access, no system files, no escapes. The workspace boundary is enforced at the architecture level — not a config flag you can toggle off.
The pipeline from prompt to production. Every step is auditable.
Where we are. Where we're going.
