Rolling Your Own APM with Claude: Real Wins, Real Tradeoffs

Rolling Your Own APM with Claude: Real Wins, Real Tradeoffs

Ryan and Brendan talk through the growing pains of AI-assisted development — including fatigue, increased confidence in bigger code changes, and what happens when you stop paying for expensive APM tools and just build your own. Ryan walks through how he used Claude to identify memory pressure, fix N+1 queries, and cut his Heroku costs significantly in just a few days. They also dig into the real tradeoffs: maintenance burden, over-optimization, and why you still need to understand what Claude is telling you before you run anything on a live database.

Scott Werner Returns

Scott Werner (Sublayer) returns to discuss how rapidly AI and agentic coding have is changing.  The hosts and Scott dig into why niche tools are increasingly getting replicated by developers and hobbyists with "good enough" custom solutions — while complex enterprise platforms may actually have more staying power. Scott shares what he's seeing at the Artificial Ruby meetups. They also cover Stripe's "forward deployed" AI role, the reality of AI consulting, growing trust in AI-written code, and orchestration tools like Fabro [https://fabro.sh/] for defining repeatable AI workflows. 01:03 Early Agentic Coding Days 04:49 SaaS Is Dead Debate 10:28 Enterprise vs Homegrown Systems 12:52 Forward Deployed Builders 15:20 Architects Still Matter 19:33 Personal Software vs Production 23:22 Stripe Forward Deployed AI Role 26:16 AI Adoption and Consulting Window 29:42 Games and What Software Becomes 33:20 Burnout and Pairing Lessons 36:06 Learning to Trust AI Output 38:57 Requirements Over Code Style 43:02 Multi Project AI Workflow 45:36 Software Factory Orchestration 54:40 Process Thinking and QA 56:41 Skills and Non Determinism LINKS - Sublayer Website [https://www.sublayer.com/] - Scott's Blog (Works on My Machine) [https://worksonmymachine.ai/] - Ryan's Website [https://www.frisch.fyi/] - Brendan's X/Twitter [https://x.com/brendanwb] - Brendan's Bluesky [https://bsky.app/profile/brendanwb.bsky.social] Questions or comments, email us at railsbusinesspod@gmail.com Send us Fan Mail [https://www.buzzsprout.com/2435951/fan_mail/new]

Is Data the Moat for Your Business?

The hosts explore whether “data is the new moat” in SaaS and argues that data alone—especially customer data—is rarely defensible as extraction and migration get easier. Instead, moats increasingly come from clear product vision, differentiated approaches, integrated systems, and how well apps enable AI and humans to interact with structured data. They contrast niche SaaS with broad platforms like HubSpot and Salesforce, discuss pricing model changes driven by AI costs (moving beyond per-seat to metered/credits), and predict reduced reliance on traditional UIs as chat and CLIs become efficient interfaces for AI-to-backend communication. 00:00 Data as a Moat 01:52 Niche vs Platform SaaS 02:45 Integrations and UX Moats 05:31 AI Changes Pricing Models 06:48 Geocoding Data Example 08:35 When Not to Use AI 10:43 Why CLIs Are Rising 14:25 Future Without Interfaces 18:43 Data Product vs Customer Data 21:28 Opinionated SaaS Wins 23:19 AI Change And Strategy 23:48 Defensibility And Platform Risk 25:19 Building A Command Center 27:30 Top Tools In The Stack 27:52 Do You Still Need UIs 30:36 Second Brain For Priorities 33:37 Frameworks And Memory Systems 36:02 SaaS Moats In An AI World 39:23 AI Beyond Tech Businesses 41:35 Business Takeaways And Wrap LINKS * Ryan's Website [https://www.frisch.fyi/] * Brendan's X/Twitter [https://x.com/brendanwb] * Brendan's Bluesky [https://bsky.app/profile/brendanwb.bsky.social] Questions or comments, email us at railsbusinesspod@gmail.com Send us Fan Mail [https://www.buzzsprout.com/2435951/fan_mail/new]

Do Pull Request Reviews Still Matter in the Age of AI?

The hosts once again discuss the recurring theme of AI’s impact on development workflows.  They discuss various topics, including:  * Increased PR volume from AI-assisted coding and whether traditional pull request reviews are still necessary.  * Should AI be used earlier for pre-PR review and stronger CI guardrails for performance and security.  * What is the role of automated testing, and are they even more important as code generation accelerates? 01:05 PR Reviews Under AI Load 02:38 What PR Review Is For 05:02 Human Review What Remains 08:36 AI Pre Review And PR Purpose 11:01 Guardrails CI Performance Security 12:39 TDD Tests As Behavior Spec 15:53 AI Versus Automation In Pipeline 19:17 Testing Evolution Unit Vs System 20:32 Feature Specs And Functional Review 21:35 Bugs vs Defects Focus 23:37 Smoke Tests for Upgrades 24:44 Controller Tests Debate 27:40 Test Pyramid and Frontend Gap 28:37 Refactoring for Unit Tests 30:57 AI Coding Raises Review Stakes 34:00 Claude MD Friction 35:54 Wrap Up and Testing Habit LINKS * Justin Searls Podcast [https://www.youtube.com/watch?v=60S_U2jCDOg] * Working Effectively with Legacy Code Book by Michael Feathers [https://www.amazon.com/Working-Effectively-Legacy-Michael-Feathers/dp/0131177052] * Professional Rails Testing: Tools and Principles Book by Jason Swett [https://www.amazon.com/Professional-Rails-Testing-Tools-Principles/dp/B0DJRLK93M/ref=sr_1_1?crid=1A1ATFUTEYQPU&dib=eyJ2IjoiMSJ9.wZqHxKrtw7kHFqbnq0cJFGb39AG0-L-JIs5n2E8mhvjGjHj071QN20LucGBJIEps.Igt2xtW3jqDiVfsKd117j5ffdxrdq0BBdEObr0XkdPQ&dib_tag=se&keywords=jason+swett&qid=1777520728&s=books&sbo=RZvfv%2F%2FHxDF%2BO5021pAnSA%3D%3D&sprefix=jason+swett%2Cstripbooks%2C144&sr=1-1] * Ryan's Website [https://www.frisch.fyi/] * Brendan's X/Twitter [https://x.com/brendanwb] * Brendan's Bluesky [https://bsky.app/profile/brendanwb.bsky.social] Questions or comments, email us at railsbusinesspod@gmail.com Send us Fan Mail [https://www.buzzsprout.com/2435951/fan_mail/new]
