open-source

A self-hostable SMS relay for AI agents that uses an old Android phone and a prepaid SIM, exposed over MCP so clients like Claude, ChatGPT, and Cursor can send and receive real texts.

Ironsmith is an open-source macOS menu bar app that generates small native SwiftUI apps from prompts, using local or hosted LLMs.

SpadeBox is an open-source sandboxed tools and JavaScript runtime for AI agents, with Rust core plus JavaScript and Python bindings. It provides file, network, and code-execution tools, supports MCP, and includes examples for JavaScript, Rust, and Python.

A 150M ModernBERT-based token classification model that extracts verbatim evidence spans for RAG and related pipelines, reducing the need for an LLM call to highlight answers.

RiskKernel is an open-source, self-hosted reliability runtime for AI agents. It adds hard budgets, kill switches, crash-resumable runs, human approval gates, and OpenTelemetry export, with support for OpenAI, Anthropic, and existing agent stacks.

Linux-only kernel-level audit feed for Claude Code or other matched agent sessions, streaming exec, file, and network activity in real time.

A TypeScript stealth browser runtime for AI agents that drives real Chrome over raw CDP, with MCP support and accessibility-tree based interaction.

Lowfat is a lightweight CLI tool that filters noisy command output before it reaches an AI agent, with plugins, shell integration, and usage stats for token savings.

JetBrains introduces Mellum2, an open-source 12B model built for software engineering workflows, routing, Q&A, RAG, sub-agents, and private deployment.

Open-source C++ and CUDA LLM inference engine inspired by vLLM, with a teaching-focused course that walks through model serving, batching, KV cache, and attention kernels.

Open-source SDK for governing AI agent tool calls before side effects happen, with policy enforcement, approval flows, audit logs, and local execution.

TokenBBQ is an open-source dashboard and CLI that tracks token usage and estimated costs across Claude Code, Codex, Gemini, OpenCode, Amp, and Pi-Agent from local files on your machine.

An open-source 26M parameter function-calling model designed to run on very small devices, with a local quickstart, Python usage, and a playground for testing and finetuning.

Open-source email gateway for AI agents with SPF/DKIM verification, HMAC-signed delivery, webhook and WebSocket fan-out, plus CLI and SDK support.

A local coordinator for parallel AI coding agents. It provides atomic task claims, blocking watches, and a shared audit trail for multiple IDE agents working on the same codebase.

A local MCP server for AI coding agents that records why code changes were made and stores that history in SQLite next to the project.

Open-source platform for governing AI agents across clouds and stacks, with a control plane, sidecar-based data plane, policy enforcement, observability, and audit trails.

An open-source memory governance layer for AI agents. It adds deduplication, conflict detection, decay, archival, and explainable retrieval so agent memory can be managed with more control than passive storage.

Open-source tool for visualizing and analyzing AI agent sessions, with personalization tips, dashboard analytics, and support for multiple coding agents.

Nimbalyst is a visual workspace for building with Codex, Claude Code, and other coding agents. It combines collaborative editors, session management, task tracking, git/worktree tools, and a mobile app for managing agent work on the go.

Open-source, local-first desktop workbench for coding agents. It centralizes tasks, sessions, transcripts, artifacts, diffs, containers, and merge-queue state for agents like Claude Code, Codex, and Cursor.

Subarr is an open-source coordination layer for the *arr subtitle stack. It adds subtitle coverage tracking, audio-language verification, provider success tracking, queue management, Whisper tuning, and post-transcription quality checks for Bazarr/Subgen workflows.

Self-hosted runtime for putting hard budgets, approval gates, observability, and resumable checkpoints around AI agents.

Open-source terminal coding agent in Rust with LLM-native code understanding, shell safety, multi-provider support, and automatic failover.
