Introducing: ✨ Agent Experience (AX) Tier List ✨ One question prompted this: Can an agent sign up for a service on its own? We scanned dozens of providers to see where they stand in terms of login flow, bot protection, paywall and sign-up Here's what agents can actually sign up for, fully autonomously as of Sep 17, 2026: @mastra, @clerk, @WorkOS, @IntrospectionAI, @Netlify, @AnchorBrowser, @ElectricSQL, @sanity_io, @vercel, @neondatabase, @upstash Others like @modal, @supabase, @daytonaio, @resend, @mintlify, @agentmail, @ExaAILabs, @langfuse require at least one step that involves a human in the loop Full list is on 2027.dev/axlist All signup flows are shown in their respective tiers: S (fully hands off), A (just confirm), B (copy a key), C (figure it out) and D (blocked) DM me for your full report 👋 And if you want to be added here, send a tool request :) cc @calcsam @abhiaiyer, @tweetsbycolin, @_Dapp, @biilmann, @JavaSquip, @nicknisi, @grinich, @MelkeyDev, @andrewqu, @andrelandgraf, @andyhattemer, @kmelve, @enesakar, @cahidarda, @cpenned, @zenorocha + more builders

We're hosting a roundtable discussion on the OpenAI/Hugging Face attack in SF on Sep 23rd. Some preliminary reading is required - super excited for this one! Registration link incl. reading list below 👇

Final day of @clerk Growth Shop: measurement and testing. As onboarding moves into the CLI, traditional web attribution only tells part of the story. We’ve begun to map a new funnel & started evals with @gauge_sh & @2027dev to understand performance & find where agents get stuck. This frames the attribution challenge clearly without feeling uncertain & gives us forward momentum for measurement framework.

Hot take: we need to prompt our agentic users to navigate products the same way we prompt agents to build them in the first place The future of UX (which, inevitably, is AX - Agent Experience) is all about steering agents onto a happy path, so they can achieve the desired outcome on behalf of humans It’s not enough to just ship docs/llms.txt/CLI. With non-deterministic users like AI agents, gathering data about what they frequently do and creating guides to steer them towards a happy path are the way to go (hint: error messages are a guide too) It’s easier said than done, and I shared some of our thinking and demoed @2027dev at the @convex Agentic Builders Night last week! In the fast moving space we’re in, the most valuable best practices are usually in rooms at in-person meetups like this Thanks @waynesutton for having us, and honored to have shared the stage with @thescottfan of @ParadigmStudy, @gary_qz of @Trae_ai, @danieltian at @PhotonHQ and @pederzh of @manufact ✨ See you at the next one!

Looking forward to tonight’s Agentic Builders Night at @convex with speakers from @bondaicommunity @ParadigmStudy, @Trae_ai, @PhotonHQ, @manufact & @2027dev covering coding agents, autonomous agents, agent-native interfaces, and reactive backends: 1. Scott Fan (@thescottfan), founder of @ParadigmStudy and maintainer of @openclaw 2. Gary Qi (@gary_qz), Developer Operations Manager at @Trae_ai 3. Daniel Tian @danieltian, Co-Founder @PhotonHQ 4. Balázs Némethi (@nembal), founder of @agentcommunity_ 5. Luigi Pederzani (@pederzh), co-founder of @manufact (@ycombinator S25) 6. Mika @heymikasagi co-founder and ceo of @2027dev Join us: luma.com/convex-yrhb

3.5 months later, we’re in a new beautiful office! who wants to come hang and cowork? thinking of hosting a cowork day soon :)

We haven’t hosted a demo night at WorkOS in a while. Who wants to show the latest stuff they’ve been building? We’ll order pizza and drinks. 🍕

GPT 5.6, Grok 4.5 and Fable 5 are now live on 2027.dev✨ You can run Agent Experience evals in different model x harness setups, including this week's latest releases + see where agents face friction Excited to see how the newest additions of @openai, @grok and @claudeai stack up when using devtools 🫡

New category drop on the Arena: ✨AI agent frameworks✨ Agent Experience (AX) update as of 06/26: 1/ @LangChain LangGraph 2/ @vercel AI SDK 3/ @crewAIInc 4/ @mastra For context: we evaluate how easy it is for AI agents to get started with devtools, fully autonomously With AI agents becoming the primary consumers of docs and APIs, AX is the natural evolution of DX more on on 2027.dev/arena DM me or @2027dev for the full report! What tools / categories should evaluate do next? 🔥 cc: @hwchase17 @j_schottenstein @jakebroekhuizen @joaomdmoura @calcsam @abhiaiyer @jesse_miller @andrewqu @rauchg @nickoates_ @31Carlton7 @smthomas3
