Open-Source AI Sales Agent Runs 24/7 on WhatsApp for Small Merchants

·1 views

A developer built SellBot, an autonomous sales agent that operates inside WhatsApp using open-source AI models and self-hosted tools. The project was motivated by small businesses like a home bakery losing customers who received inquiries while owners were busy and could not reply promptly. Unlike rigid rule-based chatbots, the agent interprets natural-language and multilingual messages, searches a product catalog, checks stock, and calculates prices. It can also generate localized payment requests such as UPI QR codes, JazzCash, and Cash on Delivery. The project was submitted to Hacktoberfest 2026.

ColdCraft Studio Drafts Personalized Cold Emails Locally at No Cost

ColdCraft Studio is a local-first tool for B2B cold outreach that helps freelancers and consultants write tailored pitches without spending long periods on manual research. It scrapes a prospect's website, keeps the main headings and paragraphs, and identifies a relevant talking point. An open-weight model, qwen2.5:3b, running through Ollama on the user's own machine then drafts the email in a structured format. Because the process runs offline, there are no per-email API fees and prospect data stays on the user's computer. The project's creator argues this approach suits indie developers and small businesses that want to avoid cloud AI costs and privacy concerns.

Seven-layer memory architecture for a local AI agent: lessons from building it

The author describes building a seven-layer memory system for a local AI agent called Hermes Sterling, aimed at retaining facts and decisions without loading the full history into every prompt. The design separates always-available Markdown files from on-demand retrieval using SQLite, FTS5, local embeddings and related components. The team framed memory as five distinct problems: persistence, retrieval, provenance, cost and integrity. Its most useful findings came from negative results, including a metric that was mathematically impossible and a timeout shorter than the model's cold load. The article is explicitly a single-environment case study, not a general framework comparison.

Why Building Your Own Authentication Is Harder to Maintain Than to Write

Writing a basic login system is quick, but keeping it secure over time is where the real cost lies. Password hashing settings must be periodically raised as hardware improves, which requires an upgrade path for existing hashes. Data protection keys expire and rotate, and losing them makes protected data permanently unreadable. Token-based systems add certificates with their own expiry and rotation needs, and OAuth security guidance such as RFC 9700 evolves, so implementations can fall out of line without code changes. The article argues that frameworks like ASP.NET Core Identity are reasonable foundations, while the ongoing maintenance burden remains even when using them.

RepoGraph AI uses a FalkorDB graph to rank files for Oppia open-source issues

RepoGraph AI is a tool built for Graph Hacks that takes an issue from Oppia, an open-source learning platform, and ranks the files worth investigating, suggests tests, and shows the graph evidence behind each recommendation. It connects Git history, GitHub issues, and Python code structure in a FalkorDB graph of roughly 25,700 nodes and 39,000 edges, with each link labeled by its source and reliability. The author reports that graph-enhanced search found a relevant file in the top five for 20 of 29 issues, compared with 18 for keyword search, though the gains are modest. The graph alone performed worse than keyword search, and the tool is designed to state when evidence is insufficient rather than give a confident guess. The author frames the project as a test of whether connected historical and structural evidence makes investigation more useful and explainable, not as proof that graphs solve issue localization.
