Back when we introduced MCP support , we ended on a teaser: Phase 3 would tackle Sampling —letting servers request completions from the host instead of only exposing tools and resources to it. NodeLLM 1.17 delivers on that, and pairs it with a second, unrelated but overdue improvement: precise control over how tool calls execute, now available consistently in both core and the ORM persistence layer. 🔄 MCP Sampling: Closing the Loop Sampling inverts the usual MCP direction. Instead of the client asking the server for tools, the server asks the client to run an LLM completion on its behalf. This lets an MCP server offer LLM-powered capabilities—summarization, classification, drafting—without needing its own API key or provider integration. createLLMSamplingHandler answers those requests using a real NodeLLM instance, so a server's tool ends up powered by whatever model you configure client-side: import { createLLM } from " @node-llm/core " ; import { MCP , createLLMSamplingHandler } from " @node-llm/mcp " ; const llm = createLLM ({ provider : " openai " }); const mcp = await MCP . connect ( { command : " node " , args : [ " ./sampling-server.mjs " ] }, { sampling : createLLMSamplingHandler ( llm , " gpt-4o-mini " ) } ); const tools = await mcp . discoverTools (); // The server only advertises sampling-backed tools once it sees // the client declared sampling support during the handshake. If you need full control over how a sampling request is answered—routing by model hint, injecting your own guardrails—pass a plain handler function instead of { llm, model } . It receives the raw sampling/createMessage params and returns a CreateMessageResult , so you decide exactly how (or whether) to answer. ⚡ Concurrent Tool Execution When a model returns several independent tool calls in the same turn, NodeLLM has always executed them one at a time. That's safe by default, but wastes time when the calls don't depend on each other—three weather lookups for three different cities, s
The State of Changelog Tools for Indie SaaS in 2026
If you're a solo founder or small team shipping on GitHub, at some point someone asked you: "what changed in the last release?" And if you're honest with yourself, your answer was probably a Notion page nobody reads, a GitHub releases tab your users don't know exists, or "I'll get to it." A changelog sounds like a low-priority vanity feature. But here's what I've learned building a SaaS: when you ship frequently and users don't know what changed, they churn quietly — not because the product got worse, but because they never noticed it got better. Why Headway stopped being the answer For years, Headway was the indie-hacker answer to this problem. Beautiful in-app widget, dead simple setup, priced reasonably. A lot of us put it in our sidebars and called it done. The problem: Headway hasn't shipped a meaningful update since roughly 2020. No GitHub sync. No AI generation. No email notifications to push updates out to users. The integration ecosystem it was built for has moved on, and the product hasn't. Search "Headway alternatives changelog" and you'll find threads on Indie Hackers and Reddit full of people actively looking for something else. That's not a dead category — it's one where the go-to tool has been abandoned and nobody decent has filled the gap at the indie-hacker price point. What's actually available in 2026 Here's an honest look at the main options: Tool Price AI generation GitHub sync Email digest In-app widget Headway $29/mo No No No Yes AnnounceKit $79-129/mo Partial No Yes Yes Beamer $49-499/mo No No Yes Yes Shiplog $19/mo Yes Yes Yes Yes A few things worth noting: AnnounceKit is well-built and widely used. If you're a funded team or have a larger user base that needs NPS surveys and user segmentation, it earns its price. For a bootstrapped founder, $79/mo for a changelog widget is hard to justify before you're at serious MRR. Beamer is similarly full-featured and similarly priced for growth-stage SaaS teams. Their entry tier has gotten more reasona
AI-DLC: Giving Structure to AI-Assisted Development
AI coding assistants are great at writing code and terrible at knowing when to write it. Ask one to build a feature and it will happily jump straight to implementation, skipping the questions a good engineer asks first: what exactly are we building, why, what are the risks, and how should it be broken down? The result is fast output that often solves the wrong problem. AWS's AI-DLC (AI-Driven Development Life Cycle) is an attempt to fix that gap. It's an open-source set of workflow rules — released by awslabs — that steer AI coding agents through a disciplined software development process instead of letting them freewheel. Importantly, it isn't a tool you install or a service you pay for. It's a methodology delivered as a bundle of markdown rules that your existing coding agent reads and follows. The core idea: methodology over tooling One of AI-DLC's stated tenets is "methodology first." The whole thing ships as plain markdown rule files that you drop into whatever your agent already uses for project instructions — CLAUDE.md for Claude Code, .cursor/rules/ for Cursor, .github/copilot-instructions.md for GitHub Copilot, .amazonq/rules/ for Amazon Q, steering files for Kiro, and so on. There's nothing to run. The agent loads the rules and its behavior changes. This makes AI-DLC deliberately agnostic . It doesn't tie you to a specific IDE, model, or vendor — any coding agent that supports project-level rules can use it. The philosophy is that a good development methodology should outlive any particular tool. A three-phase adaptive workflow At its heart, AI-DLC organizes work into three phases that mirror how thoughtful software actually gets built. The Inception phase answers what to build and why . This is where the agent does requirements analysis, creates user stories when they're warranted, sketches the application design, breaks work into units that can be built in parallel, and assesses risk and complexity before a line of code is written. The Construction phase
How I built a real-time whale tracker for Polymarket using Node.js and a CLI
The 2026 World Cup has $3.89 billion bet on it across Polymarket. That's not retail money — that's whales. I built WhaleTrack to track exactly what those big wallets are doing. Here's the stack: Backend: Node.js server fetching live data via Bullpen CLI Frontend: Vanilla JS, real-time updates Data: Polymarket CLOB API via Bullpen Analytics: Google Analytics for traffic tracking The hardest part wasn't the code — it was getting users. Pure SEO and content distribution (Reddit, Twitter, IH). The site is live at whaletrack.app — would love feedback from devs on the UX and performance. Happy to open source parts of it if there's interest.
Privacy Isn't a Checkbox — It's Architecture
Privacy isn't a checkbox. It's not a statement in your terms of service. It's not a toggle in your settings app. Privacy is architecture. And most apps get this backwards. The Architecture Test Here's a simple test for any app that claims to be "privacy-first": If your server goes down, can anyone still access user data? If the answer is yes, your privacy is a policy question — not a technical guarantee. You've built a system where trust in the company replaces trust in the code. Every photo cleaner that uploads your images to a server has already failed this test. The moment data leaves your device, privacy becomes something you promise rather than something you enforce . What On-Device Processing Actually Means When we built Swipe Cleaner, we made one architectural decision that defined everything else: zero data leaves the phone . This means: No cloud processing of photos No API calls that transmit image data No server-side storage of any kind Every scan, every classification, every cleanup happens locally The app is 4.7 MB. That's it. There's nothing to hide because there's nowhere to hide anything. Why Architecture Beats Policy Companies spend millions on legal teams writing privacy policies that their architecture contradicts. They collect data "to improve the service" while the service could have been designed to not need that data in the first place. Policy-based privacy Architecture-based privacy "We promise not to misuse your data" "We can't misuse data we never have" Requires ongoing trust Verifiable by anyone Can change with an update to ToS Requires rewriting the entire app Compliance-driven Principle-driven The Trust Problem Here's what I've learned building privacy-focused tools: users can't verify your privacy policy. They can't audit your servers. They can't check if you're actually deleting their data after processing. But they can verify that an app never sends their photos anywhere. They can check network traffic. They can inspect the binary. Tha
Add a post-quantum readiness gate to your CI in 5 lines
Your codebase almost certainly relies on RSA and elliptic-curve cryptography — TLS, JWTs, SSH keys, signed tokens. All of it is breakable by a large enough quantum computer (Shor's algorithm), and "harvest now, decrypt later" means data you encrypt today can be captured today and decrypted later. Regulators noticed: CNSA 2.0 (US federal + suppliers), DORA (EU financial entities, applies from Jan 2025), and NIS2 now mandate strict cryptographic risk management — which in practice means knowing where your quantum-vulnerable crypto lives, a cryptographic bill of materials (CBOM). Most teams can't answer "where is our RSA/ECC?" off the top of their head. Here's how to make CI answer it for you, on every push, for free. What we're building A GitHub Action that scans your repo, grades its post-quantum readiness A–F , writes a CycloneDX 1.6 CBOM , and — if you want — fails the build when classically-broken crypto (MD5, RC4, 3DES, deprecated TLS) shows up. Step 1 — try it in your browser first (30 seconds, nothing uploaded) Before touching CI, paste a package.json / requirements.txt / cipher list into the in-browser scanner and see your grade. It runs entirely client-side — no upload: https://throndar.ai/cbom Step 2 — add it to CI (the 5 lines) # .github/workflows/pqc-readiness.yml name : PQC readiness on : [ push , pull_request ] jobs : scan : runs-on : ubuntu-latest steps : - uses : actions/checkout@v4 - uses : brandonjsellam-Releone/pq-readiness-scorecard@v1 with : path : . That's it. The Action is self-contained and dependency-free — no npm install , no setup step. On the next push it prints a scorecard to the job summary: Post-Quantum Readiness Scorecard: D (52/100) — Quantum-vulnerable — migrate 3 files · broken-classical 0 · quantum-broken 4 · weakened 1 · resistant 0 Step 3 — see findings in the Security tab (SARIF) The Action emits SARIF 2.1.0. Upload it and every finding shows up as a code-scanning alert: - id : pqc uses : brandonjsellam-Releone/pq-readiness-score
AgentGuard vs Semgrep vs CodeQL: 100 Percent vs 0 Percent on AI Agent Security
I ran the same 39 AI agent security samples through three scanners: AgentGuard, Semgrep, and CodeQL. The Results Scanner Detection Rate False Positives AgentGuard v0.6.4 100% (39/39) 0 Semgrep 0% (0/39) 0 CodeQL 0% (0/39) 0 Zero. Semgrep and CodeQL detected nothing. They have zero rules for AI agent security. AgentGuard has 17 detection rules covering all 10 OWASP ASI categories plus 4 novel attack vectors: Memory Poisoning, Tool Output Trust, Action Chain Amplification, and Multi-Agent Collusion. Real World AgentGuard found 332 critical vulnerabilities across Microsoft AutoGen and LlamaIndex. Issues reported directly: autogen#7917, autogen#7918, llama_index#22245.

Exporting any Bluesky profile's followers with the open API
Every big social network locks audience data behind auth walls and anti-bot systems. Bluesky went the other way. The AT Protocol is open by design, so public profile data (bios, follower counts, full follower and following lists) is queryable through a documented API without logging in. The whole surface is basically two endpoints: GET https://api.bsky.app/xrpc/app.bsky.actor.getProfile?actor=HANDLE GET https://api.bsky.app/xrpc/app.bsky.graph.getFollowers?actor=HANDLE&limit=100 There's also getProfiles for batching 25 handles per call. Follower lists paginate with a normal cursor , which still works on the graph endpoints. Search is a different story, cursor pagination 403s there now, but that's a topic for another post. For one-off lookups, curl is honestly all you need. Where it gets tedious Bulk. Thousands of profiles, follower exports that run into six figures, weekly snapshots for tracking. Pagination, rate-limit backoff, and stitching the pages together is boring code that has to run reliably. I packaged that part as an Apify actor: Bluesky Profile Scraper . Paste handles or profile URLs, optionally turn on follower/following export, and you get JSON or CSV back with a sourceProfile field linking each follower record to the profile it belongs to. $2 per 1,000 records, runs on a schedule if you want snapshots over time. What people use this for Vetting an influencer's real audience before paying them. Exporting who follows a competitor and what their bios say. Charting follower growth from weekly runs. And enrichment: find who's talking about you with a mentions monitor , then profile those authors to see their actual reach. Bluesky is the only major network right now where any of this is straightforward and stable. Worth using while it lasts.
