Other coding tools in our directory. See all coding tools →
OpenAI Codex CLI
OpenAI's open-source coding agent for the terminal; also runs in the cloud.
opencode
Open-source terminal coding agent that works with many model providers.
Codewhale
Rust agent engine and terminal coding client with model choice, tool approvals and review flows.
Pi
Minimal, extensible open-source terminal coding agent and agent toolkit from Earendil, with a multi-provider LLM API, TypeScript SDK, RPC mode and installable extensions, skills and themes.
Paritok
Paritok is a compression gateway that sits between a coding agent and its LLM. Using its own open-source 4B code-aware model, it shrinks tool output, files and conversation history on the fly without losing what the agent needs, which cuts token bills and lets agent sessions run longer before they hit context limits.
Elephant-Goldfish Model
Elephant-Goldfish Model is an open-source method and plugin from Google for spec-driven development with AI coding agents. A deep-context agent drafts the design, then fresh zero-context subagents stress-test that spec for gaps and wrong assumptions before any code is written, which catches problems that a single long-running agent tends to miss.
