goose
an open source, extensible AI agent that goes beyond code suggestions - install, execute, edit, and test with any LLM
-
OpenFang is an operating system for autonomous agents. Not a framework. Not a wrapper. An actual OS, written from scratch in Rust by RightNow AI. 137,728 lines of code across 14 crates. Compiles to a single 32MB binary with zero external dependencies. This is not something someone cobbled together over a weekend.

Project mention: Docker Sandboxes – Disposable, isolated sandboxes for AI agents | news.ycombinator.com | 2026-08-09
it's been mentioned on this thread already, we think https://github.com/superradcompany/microsandbox/ is the closest OSS to it and we have a great DX and improving.

Project mention: MCP new specs in Practice: Testing the Stateless Revolution on AWS AgentCore Gateway | dev.to | 2026-08-01
AAIF's agentgateway is the open-source counterpart to managed gateways like AgentCore. My next post will compare how agentgateway v1.3 and AgentCore Gateway each handle MCP 7-28 -- same protocol, different deployment models, different tradeoffs.

sentrux
Real-time architectural sensor that helps AI agents close the feedback loop, enabling recursive self-improvement of code quality. Pure Rust.
Project mention: Sentrux – AI keeps writing bad code. Built a feedback sensor that grades it live | news.ycombinator.com | 2026-03-12 -
moltis
A secure persistent personal agent server in Rust. One binary, sandboxed execution, multi-provider LLMs, voice, memory, Telegram, WhatsApp, Discord, Teams, and MCP tools. Secure by design, runs on your hardware.
Project mention: OpenClaw Is a Security Nightmare Dressed Up as a Daydream | news.ycombinator.com | 2026-03-22I'm on my 3rd "claw" variant (currently https://github.com/moltis-org/moltis). I had the same issues you had. Moltis is better (at the moment).
-
webclaw
Fast, local-first web content extraction for LLMs. Scrape, crawl, extract structured data — all from Rust. CLI, REST API, and MCP server.
GitHub repo

amazon-q-developer-cli
✨ Agentic chat experience in your terminal. Build applications using natural language.
Project mention: Measuring Chat Count After Hitting the Amazon Q Developer (Claude Sonnet 4) Pro Limit | dev.to | 2025-08-30 -
-
BitFun
Cross-platform desktop AI agent for coding, documents, and desktop work, built around a Rust Agent Runtime. Supports stateful Agentic Mini Apps, custom Agents, MCP, Skills and Hooks, plus a self-hostable relay for cross-device control.
Project mention: A Remote Coding Agent Can Deadlock on a Local Permission Dialog | dev.to | 2026-08-12The implementation is open source here: https://github.com/GCWing/BitFun

weave
Entity-level git merge driver. Resolves false conflicts git invents when independent agents edit the same file. ~95% reduction vs. line-based merge. (by Ataraxy-Labs)
Project mention: Weave: Merging based on language structure and not lines | news.ycombinator.com | 2026-06-13This tool does not work. I wanted it to work. I wanted to automate merges with AI supervision. No dice. Silent corruption that wouldn't go away no matter how many issues I filed. Unacceptable. Had to disable it. https://github.com/Ataraxy-Labs/weave/issues?q=is%3Aissue%20...

Project mention: Show HN: Object-storage native graph engine with Git-style workflows | news.ycombinator.com | 2026-06-25
-
Project mention: Query Markdown as a Database with mq-db: SQL, mq, and Interval Indexes | dev.to | 2026-06-03
mq-db takes a different approach: it parses every Markdown element into a typed block, builds interval and secondary indexes, and exposes the result through SQL and a jq-inspired query language called mq.

Project mention: Your AI Agent Just Ran rm -rf / — How to Stop It Before It Happens | dev.to | 2026-03-13
shellfirm is an open-source tool that intercepts dangerous shell commands before they execute. It ships with 100+ built-in patterns covering 9 ecosystems — filesystem, git, Kubernetes, Terraform, AWS, databases, Docker, and more.

hyper-mcp
📦️ A fast, secure MCP server that extends its capabilities through WebAssembly plugins. (by hyper-mcp-rs)
i had this same vision when i created hyper-mcp with modular plugin system via WASM plugins. Too bad, the community moves on from MCP to CLI with coding agent
https://github.com/hyper-mcp-rs/hyper-mcp

macro
Macro is a unified workspace for teams: email, chat, docs, tasks, agents, calls, and CRM — @-linked together with shared AI memory. (by macro-inc)

Elasticsearch is a distributed search and analytics engine that stores data as JSON documents and lets you run fast full‑text search, aggregations, and log or metrics analysis across large datasets. Elasticsearch, prior to 7.11, used Apache License 2.0, a permissive license allowing commercial use, modification, and distribution with minimal restrictions. In January 2021, Elastic announced that starting with version 7.11, it would be relicensing its Apache 2.0 licensed code in Elasticsearch to be dual licensed under SSPL (Server-Side Public License) and the Elastic License, a strong copyleft license that requires anyone offering the software as a service to open-source the entire service stack. In August 2024, the GNU Affero General Public License was added to Elasticsearch version 8.16.0 as an option, making Elasticsearch free and open-source again. Elastic argued that large cloud providers were taking the open‑source Elasticsearch, offering it as a commercial managed service (e.g., Amazon Elasticsearch Service) and capturing much of the value without sufficient reciprocity. The license change was positioned as protecting Elastic’s SaaS/Elastic Cloud business and long‑term sustainability. OpenSearch was launched by AWS and partners as a fork later in 2021, based on Elasticsearch 7.10 and Kibana 7.10, the last Apache‑2.0 versions. Today, OpenSearch is no longer just an AWS side‑project; it is governed by the OpenSearch Software Foundation, a Linux Foundation project that provides vendor‑neutral governance and long‑term stewardship. Premier foundation members include AWS, SAP, and Uber, all of whom either run OpenSearch in production, build products on top of it, or contribute engineering resources. Among the benefits of switching to OpenSearch:

probe
AI-friendly semantic code search engine for large codebases. Combines ripgrep speed with tree-sitter AST parsing. Powers AI coding assistants with precise, context-aware code understanding. (by probelabs)
Project mention: Get Shit Done: A Meta-Prompting, Context Engineering and Spec-Driven Dev System | news.ycombinator.com | 2026-03-17how big is the codebase? how often is the agent writing to memory? you might be able to get away with just appending it to the project's CLAUDE.md? you might also want to check out https://github.com/probelabs/probe

flow-like
Flow-Like: Strongly Typed Enterprise Scale Workflows. Built for scalability, speed, seamless AI integration and rich customization.
Project mention: Flow-Like – Local-first workflow automation with WASM nodes (Rust) | news.ycombinator.com | 2026-04-02
