Production-grade coding agent tools in Rust. ~10 MiB. No TUI. Embed it anywhere.
ReloadedCode started as "an OpenCode for servers." Headless, sandboxed, and cheap to host for non-commercial use.
[OpenCode] is a great interactive coding agent, but it's a ~305 MiB TypeScript application that runs as a separate process. What if you need those same tools for a server? A Discord bot? A CI pipeline? A custom product?
ReloadedCode ships the same agent tools as a Rust library. Shell sandboxing. Default-deny permissions. ~10 MiB footprint.
| OpenCode | ReloadedCode | |
|---|---|---|
| Language | TypeScript | Rust |
| Memory | ~305 MiB | ~13 MiB |
| Interface | TUI / Desktop / IDE | Library (headless) |
| Agent format | Markdown + YAML | Similar format |
| Embeddable | HTTP API | Rust crate |
- 10 Built-in tools - read, write, edit, glob, grep, bash, webfetch, todoread, todowrite, task
- Agents similar to [OpenCode] - load agent markdown files with YAML frontmatter
- Multi-agent delegation - orchestrator pattern with depth-limited task chains
- Linux sandboxing - bubblewrap profiles for shell isolation (Public Bot + Trusted Maintenance)
- Path security - restrict file access with allowed directories and glob-based rules
- Model catalog - sync models.dev with ETag caching (~3000 models, ~24 KiB cache)
- Permissions - default-deny with last-match-wins rules and wildcard patterns
- Optimized system prompt - auto-generated, ~2000 tokens full / ~560 search-only
- Async + Sync - every tool compiles as tokio async or blocking. Zero overhead.
- Framework-agnostic core - use the serdesAI integration or bring your own framework
- 15 LLM providers - OpenAI, Anthropic, Google, Groq, Mistral, Ollama, Azure, Bedrock, and more
- Semver-guaranteed API - 6-platform CI matrix, 11 semver surfaces, clippy -D warnings

reloaded-code-serdesai = "0.2"1. Create an agent file (markdown + YAML frontmatter similar to [OpenCode]):
---name: codermode: alldescription: A coding agent that can read, search, and edit files.permission:

You are a coding assistant. Use the available tools to complete the user's task.2. Load the catalog, build the agent, and run:
use reloaded_code_agents::{AgentCatalog,AgentLoader,AgentRuntimeBuilder};use reloaded_code_core::CredentialResolver;use reloaded_code_models_dev::ModelsDevCatalog;use reloaded_code_serdesai::{AgentBuildContext,AgentDefaults};use std::{path::PathBuf, sync::Arc};#[tokio::main]asyncfnmain() -> Result<(),Box<dyn std::error::Error>>{// Load agents from the "agents" directory.letmut catalog = AgentCatalog::new();AgentLoader::new().add_directory(&mut catalog,"./agents")?;// Supports any model from https://models.devlet load_result = ModelsDevCatalog::load().await?;let runtime = AgentRuntimeBuilder::new().catalog(catalog)// Default model if not specified by agent..defaults(AgentDefaults::with_model("synthetic/hf:MiniMaxAI/MiniMax-M2.5")).build()?;let build_context = AgentBuildContext::new(Arc::new(runtime),Arc::new(load_result.catalog),Arc::new(CredentialResolver::new()),);let agent = build_context.build("coder")?;let response = agent.run("Find all TODO comments in src/",()).await?;println!("{}", response.output());Ok(())}| Crate | Version | Description |
