Hexabot is a self-hosted, fair-core AI chatbot and workflow automation platform that helps developers build production-ready AI agents by combining LLM reasoning with deterministic actions, API integrations, memory, RAG, and human handoff. The project is showing early traction with strong GitHub cloning activity, npm CLI downloads, and growing developer interest, while its main proof of usefulness is that hundreds of developers are already cloning and testing it rather than just viewing or starring it. Its long-term goal is to become a reliable foundation for teams and agencies building real AI workflows for customer support, internal operations, lead qualification, and automation use cases where black-box AI platforms are too expensive, risky, or hard to control.

MacPaw Research argues that computer-use AI systems underperform on macOS because public training datasets contain almost no Mac interface data. Their new open-source project, GUIrilla, addresses this by automatically exploring macOS applications and generating structured UI datasets at scale. The release includes GUIrilla-Task, a dataset covering over 1,100 Mac apps and 27,000 tasks, plus macapptree, a Python library for extracting accessibility metadata from Mac applications. Together, these tools aim to improve AI agents, UI understanding models, and developer tooling across the Mac ecosystem.

Free VPNs can improve security on public Wi-Fi, but not all are trustworthy. Here’s how to evaluate privacy, encryption, limits, and safety.

Free VPNs can help secure browsing on public Wi-Fi, but they are not all equally safe. Before downloading one, users should review logging policies, encryption standards, data limits, permissions, and business models. Some free VPNs collect or share user data, while others limit speed or streaming access. For sensitive work, banking, gaming, or heavy streaming, a paid VPN may offer stronger protection and reliability.

LangChain built SmithDB, a purpose-built distributed database in Rust that now powers LangSmith's agent observability. Modern AI agent traces have gotten too big and complex for general-purpose databases, with hundreds of nested spans, multi-modal content, and spans that stay open for hours. SmithDB uses an object-storage-backed LSM architecture built on Apache DataFusion and the Vortex file format, delivering P50 latencies of 92ms for trace tree loads and making LangSmith up to 15x faster. It is not a standalone product you install; it is the new data layer behind LangSmith, and it is already serving 100% of US Cloud ingestion and tracing UI traffic.

Consensus Miami 2026 made one thing clear: AI agents are about to drive up to $5T in commerce by 2030, and the race to power agentic payments is on. x402, Google's AP2, Stripe's MPP, Visa Intelligent Commerce Connect, and Mastercard Agent Pay are all fighting to own the agent-to-merchant checkout moment. But what happens when an agent needs to rebalance, repay, or move value across blockchain networks. Settlement is still up for grabs. SODAX SDK v2 (live May 2026, spans 18 networks, agent-readable docs), is building the execution system for cross-network settlement. Handing builders the tools to deploy and run their application at pace, with agent workflows in mind.
