967: What’s Going to Happen in Web Dev During 2026

Episode Summary

Executive Summary: The hosts forecast that 2026 will be a major year for web development shifts: more GPU/3D-driven experiences, a CSS renaissance, Temporal and other durable-compute workflows, standard-stack and RPC growth, and deeper AI integration across coding, testing, and observability. They also expect more security failures, acquisitions, and a broader push toward personalized software and standardized schemas.

Main Topics: WebGPU, shaders, and 3D experiences: They predict GPU-enhanced sites, shader-driven visuals, dithering, and more immersive web design will become mainstream, making websites feel more original and less generic. Modern CSS becomes truly usable: They argue 2026 will be the year modern CSS features like popover, anchor positioning, scroll animations, and scroll markers are widely adopted and reduce dependence on JavaScript. Temporal and standard stack adoption: They expect Temporal to ship broadly, and for frameworks built on standard web primitives (fetch, URL, request/response, sanitization) to gain traction for portability and simpler code. AI deepens across the dev workflow: They predict AI will move from code generation into end-to-end workflows, planning, testing, debugging, browser automation, and memory/state management for agents. Security incidents and software quality concerns: They foresee more security mishaps and outages due to AI-generated code, understaffed teams, and accelerated shipping, especially in fast-moving web companies. Tooling consolidation and acquisitions: They expect linting/formatting tools to consolidate, with Oxlint overtaking Biome, and more acquisitions of web-tech companies by larger players. Personalized software and MCP UI: They predict more people will build niche software for personal needs, and that MCP UI/custom chat widgets will become a standard way for AI systems to return interactive interfaces.

Key Arguments: Modern CSS is now rich enough to replace many JavaScript-driven UI patterns, especially for popovers, scroll interactions, and component-like styling. WebGPU and shader tools lower the barrier to visually distinctive sites, so 3D and graphical design will differentiate products from the current AI-generated sameness. Temporal and other durable workflow systems fit modern needs better than ad hoc queues because they support pausable, resumable, retryable functions. Standard schema reduces fragmentation by letting tools accept interchangeable validators like Zod or Valibot. AI will become more effective when embedded throughout the whole lifecycle, not just used to write code once. Framework choice matters less as AI tools become better at adapting to standard web APIs and primitives. Security problems will increase because teams are moving faster while relying on AI-generated code and underresourced operations. The ecosystem is likely to consolidate around a few winners in linting/formatting and workflow/durable-compute tooling.

Data Points: Predicted AI benchmark improvement: Svelte 5 reached 100% in a benchmark with Opus 4.5 - Used as evidence that AI is improving at framework-specific code generation GitHub stars: 4.3 thousand - Beads was mentioned as a rising tool for agent memory/work tracking Yearly comparison: 2026 - The entire episode centers on predictions for 2026 CSS feature count mentioned: 8+ features - They referenced many recent CSS additions including popover, anchor positioning, style queries, and scroll-related features AI improvement over the year: massive - They described large gains in coding-agent quality over the past year, though not a numeric statistic Prediction frequency: 4 years - They said they had predicted Temporal shipping for probably four years now Response quality: 80%+ hit rate - A joking reference to their previous prediction accuracy, not a precise measurement

Pivotal Quotes: "I think 2026 will be the year of durable compute." — Wes: A core prediction about pausable, resumable workflow systems like Temporal and similar products "CSS is so good." — Speaker(s): Used while discussing modern CSS capabilities replacing JS-heavy UI patterns "The framework will matter less because the AI tools will simply just pick whatever is going to work the best." — Wes: A central argument about AI reducing framework lock-in and changing how apps are generated

Implications: Web dev in 2026 may shift toward richer native browser primitives, less JS glue, more durable workflows, and AI-assisted end-to-end development. Teams that adopt standards and better tooling could move faster with fewer bugs; laggards may face more security and quality problems.
