Skillbay is a curated marketplace of AI agent skills (SKILL.md packages) that publishers and developers can browse, install, buy, or sell. Each skill includes human review and before-and-after examples, and the site exposes a JSON API and MCP server for integration.

Echologue is a local-first private voice journal app that converts quick voice notes and short entries into structured, askable memories so you can query your own history with grounded AI-powered recall.

Jotbus is an encrypted shared scratchpad for coding agents. Developers use it to pass notes and files, hand off work, and request reviews across agents and machines without copying context between terminals.

sellbonds.now is a non-custodial on-chain marketplace that lets autonomous AI agents issue and sell USDC-denominated bonds (each bond as its own smart-contract market) so agents can raise and repay capital directly on-chain without accounts or middlemen.

Oodle Agent Observability provides agent/LLM observability at scale with S3-backed columnar storage, fast search (<1s P99), out-of-the-box AI-powered insights, and flat ingestion-based pricing designed to retain 100% of traces affordably for debugging and optimizing production agents.

Moadim is an open-source loop engine that schedules and runs AI agents (Claude, Codex, Hermes, NanoClaw, Pi) against a repository or task on a recurring schedule in isolated workbenches with watchdogs and built-in HTTP/MCP interfaces.

Adchestra connects your Google marketing accounts (Google Ads, Analytics 4, Tag Manager and read-only Search Console) to any AI agent, letting the AI analyze live data, propose plans and automate approved campaign changes via a hosted MCP connector — all with a no-code setup.

Sylix is presented as a free AI code editor built in Rust, positioned as an alternative to Cursor and highlighting BYOK (Bring Your Own Key) for privacy.

Armature provides product analytics and evaluation for agent sessions that occur in AI clients (Claude, ChatGPT, etc.), capturing user intents, agent reasoning, and API calls so teams can replay sessions, surface top use cases, and identify issues.

Tines 3B is an enterprise-grade platform that provides a secure, governed environment for teams to build, run, and manage AI-native agents, apps, and automations while preserving IT and security visibility and control.

Titan is a Mac desktop AI assistant that can see your live screen, act in the apps you use, draw on screen to explain things, and remember preferences. You can give it quick requests by voice or hand off longer jobs to run while you continue working.

Sidekick by OpenHand is a desktop AI companion for telehealth visits that explains medical terms, suggests questions during the conversation, and organizes visit highlights and next steps afterward. It is currently available through a limited, free early-access program for Mac and Windows.

Agenmatic.ai is an AI-powered lead capture and engagement platform for service providers that monitors Reddit and 40+ communities in real time to detect buyer intent, draft context-aware replies, and track conversations through to conversion.

Docs.dev is a deployable documentation template that runs as a Cloudflare Worker in your account, using your GitHub repo as the source of truth and agent-powered drafting (e.g., Claude Code or Codex) to generate reviewable docs branches that your team publishes via commit.

OnlyBots.chat is a public chat board where AI bots pay to post messages for humans; posts show an amount paid, rooms have a floor price for pinned/top spots, and creators can send bots to participate.

Robot Football League (RFL) is an open, daily-streamed competitive league of simulated two-a-side Unitree G1 humanoid robots. It provides an open-source engine, rules, reference clubs and public match telemetry so developers, researchers and teams can run matches locally and qualify to have their code run on real robots.

Xalgorix is an autonomous AI pentesting platform that runs exploit-verified security tests against web apps and repos, reproduces findings with working exploits, and provides remediation guidance, CI gating, and auditor-ready reports.

Parley is coordination infrastructure for autonomous AI coding agents that provides durable message delivery, human-in-the-loop escalation, file-claim soft-locks, and an append-only flight recorder for auditability, aimed at teams running agent fleets.

AuditBadger is an AI-assisted compliance workspace that helps small teams and startups prepare for and maintain SOC 2 and ISO 27001 programs by generating policy drafts, mapping controls, tracking evidence, and producing an auditor-ready workspace.

TamedTable is a source-available AI-first ETL tool that lets you load tabular data, issue natural-language commands to clean, enrich, classify, validate, and reshape data, and then replay or export those transformation recipes (browser and CLI).

A ModelBias.ai experiment page showing results for the prompt “Public or private healthcare” across 100 trending AI models (three runs each). The page summarizes the consensus (provider-balanced) answer — Public Healthcare — and offers methodology, tech stack details, and a free downloadable dataset.

Language Model Builder is a free macOS app and interactive textbook that teaches how language models are built and lets you train small GPT-style models locally on Apple Silicon Macs.

Lanes Link (Personal Context MCP) is a private, self‑hostable middleware control plane that connects your accounts, memories and skills to every AI agent you use via a single endpoint and configurable Access Profiles.

ChatOSS is a native desktop workspace for agentic coding that runs open-source models locally via Ollama or in the cloud, letting AI agents write code in your repositories, plan and track tasks on an integrated Kanban board, and run a suite of extendable apps.
