The best Software Architecture newsletters

A principal engineer at Just Eat Takeaway writes long-form technical articles on software architecture, authentication concepts, and iOS modular design. The excerpts offer reference-style explanations and detailed accounts of real engineering decisions from a large production system.

Software architect Rico Fritzsche argues that layered architectures such as Clean and Hexagonal Architecture treat symptoms of technical dependencies rather than their assumptions. He also explores how entity-centric, CRUD-based systems strain as business processes grow, and how event-based modeling can accommodate that growth.

A weekly newsletter from Packt featuring expert-led deep dives and interviews on software architecture, engineering leadership and AI systems. Readers get practitioner perspectives on topics like AI workflow redesign and governance of agentic microservices, alongside promotion for Packt workshops.

A series-based premium newsletter from Microservices.IO aimed at CIOs and chief architects, arguing that fast software delivery flow emerges from socio-technical architecture. The excerpts cover fast flow, the limits of GenAI coding agents as amplifiers of existing capabilities, and how Team Topologies structures teams to sustain fast flow.

The Coder Cafe, written by a Google software engineer, teaches fundamental software engineering concepts such as testing mental models, distributed judgment, and systems architecture through long, narrative essays. Issues blend clear explanations, historical anecdotes, and personal experience to help engineers build lasting skills that AI cannot easily replicate.

A Tech Lead and Software Architect writes about how business people and developers are building software with AI agents and what that means for domain knowledge, team roles and process design. Recent issues also cover the cost of agentic AI usage and how organisations should own token spend through architecture decisions.

Michelin's internal IT engineering blog publishes practitioner articles on data architecture for tyre telemetry and on experiments with AI coding tools such as Copilot's Auto mode. Readers get measured, first-hand accounts of engineering trade-offs, with concrete traces and experiments rather than marketing.

This newsletter covers system design for backend engineers, with a recent focus on building reliable AI agent systems. Issues use concrete failure scenarios to explain concepts such as agent state, memory, and observability.

A software developer's blog covering Android and Kotlin architecture, including use cases as injectable functions, module naming conventions for Kotlin Multiplatform projects, and encapsulating Jetpack Compose components. Readers get code-backed explanations of practical design patterns with clear recommendations.

A weekly mobile development newsletter pairing one practical themed lesson (e.g. SwiftUI state, AI-assisted refactoring, first Android app) with a roundup of platform and tooling news. It gives readers TL;DR takeaways on iOS, Android, Flutter, React Native and Kotlin Multiplatform.

A practical newsletter for full-stack JavaScript developers aiming to think like architects, covering React, Node, software architecture and production AI systems such as LLM agents and evals. Readers get concrete, code-level guidance like testing LLM judges and debugging agent behaviour, plus occasional promotion of a Node.js book and sponsors.

A practical newsletter on engineering judgment, software architecture and AI for experienced software engineers, mixing weekly tech-trend roundups with interviews and essays on AI capabilities. Readers get condensed takeaways on coding agents, developer productivity research and how LLMs work internally.

Announcements and release notes from the creator of AutoMapper, MediatR and Respawn, plus occasional events on software architecture. Readers get updates on .NET library releases, security fixes, and Vertical Slice Architecture guidance.

A corporate engineering blog from Base-Station Private Limited publishing technical articles on backend architecture, Postgres connection pooling with Node.js, frontend performance tuning and REST API design. Readers get concrete code examples and trade-off framing for infrastructure decisions, though the excerpts read as marketing-adjacent company content.

Ahmad Nassri, a fractional CTO and startup advisor, writes short essays on software architecture, the layered abstractions beneath modern cloud computing, and the evolving role of the CTO as companies grow. Readers get a practitioner's perspective on leadership, team scaling, and technical debt.

A developer's personal blog-style newsletter covering single-page application development, with posts on GitHub-issue-based blog comments and the internals of the Aurelia JavaScript framework. Readers get practical architecture explanations and framework guidance drawn from hands-on experience.

A vendor blog from Ecotone, a PHP messaging framework, publishing tutorials and comparisons on DDD, CQRS, event sourcing and Symfony Messenger. Readers get architecture explanations and benchmark claims, though much of the content promotes Ecotone's own enterprise features.

Software engineer Luke Merrett shares personal notes from PyCon UK 2023, highlighting talks on technical debt and neglect. He also writes practical tutorials on using Mermaid for diagrams as code, including C4 architecture diagrams and Notion integration.

A weekly round-up of system design, architecture and software engineering news, with short summaries of articles from around the web on topics like AI coding agents, infrastructure efficiency and engineering practice. Readers get a quick overview of what is happening in the field and pointers to the original sources.
