Needs work

This is how AI agents (not browsers) experience supabase.com. The score weights five categories of machine-readability; the ticks on the arc are the 30 individual checks behind it.

Top fixes

Checks tagged “emerging” are 2026 agent-protocol standards most of the web hasn’t adopted yet — adopting early is an edge, not a defect.

failCanonical URLDiscoverability

No <link rel="canonical"> tag in <head>. Agents use canonical URLs to dedupe and cite.

Fix · Next.js: Set alternates.canonical in the Metadata API (generateMetadata) for each route.

failJSON-LD presentStructured data

No JSON-LD blocks found. Add a <script type="application/ld+json"> with a schema.org type for this page.

Fix · Next.js: Emit JSON-LD from a Server Component or the Metadata API: a <script type="application/ld+json"> with Organization / Article / Product for the page.

failText-to-markup ratioReadability

Visible text is 0.7% of HTML weight (8830/1312250 bytes). Low. Markup may be crowding out agent-usable text.

Fix: Heavy ad or navigation markup crowds out agent-usable text. Aim for a text-to-DOM ratio above 15%.

warnLink response headersDiscoverability

A Link: header is present but carries none of canonical/alternate/describedby — the relations agents consume.

Fix: Emit `Link:` headers for canonical, alternate-language, and describedby relations. Agents that fetch HEAD-only or stream-render rely on these.

warnHeading hierarchyReadability

Heading issues: 1 skipped level(s).

Fix: Use a single H1 and avoid skipping heading levels (H1 → H3).

failMCP server cardemergingDiscoverability

No valid MCP Server Card at /.well-known/mcp/server-card.json. Publish one so agents can discover your tools without HTML scraping.

Fix: Publish an MCP Server Card describing the tools your site exposes. Agents discover capabilities via `/.well-known/mcp/server-card.json`. See modelcontextprotocol.io for the schema.

Qualifies for certificationBronze

This score clears the Bronze threshold (70+). Certification turns it into a dated, publicly verifiable attestation — a verification URL, an embeddable badge, and weekly monitoring for a full year. Scores under 70 can’t buy this, which is what makes displaying it mean something.

How industry leaders are building with Supabase More customer stories Firecrawl Switched from Pinecone to Supabase Vector to boost efficiency and accuracy. We looked at the alternatives and chose Supabase because it&#x27;s open source, it&#x27;s simpler, and for all the ways we need to use it, Supabase has been just as performant — if not more performant — than the other vector databases.

Caleb Peffer, CEO, Firecrawl Read the story → Rally From first line of code to fully licensed fintech in three months. We could not have built this company without Supabase. If I had to go and build all these components myself, we wouldn&#x27;t even have launched. Thiago Peres, Founder &amp; CTO, Rally Read the story → Hyper An AI-native marketing platform with agents that operate across the entire workflow. I will get on a podcast and talk about how much I love Supabase. With Supabase we can move fast and build things that delight our customers without having to worry about infrastructure. Elliot Fleck, Co-founder, Hyper Read the story → E2B Secure, scalable execution of AI-generated code in the cloud. Supabase empowers us to focus on innovation rather than infrastructure.

Join us on Discord @nerdburn It’s fun, feels lightweight, and really quick to spin up user auth and a few tables. Almost too easy! Highly recommend. @adeelibr @supabase shout out, their MCP is awesome. It&#x27;s helping me create better row securities and telling me best practises for setting up a supabase app @SteinlageScott I love @supabase&#x27;s built-in Advisors. The security and performance linters improve everything and boost my confidence in what I&#x27;m building! @patrickc Very impressed by @supabase&#x27;s growth. For new startups, they seem to have gone from &quot;promising&quot; to &quot;standard&quot; in remarkably short order. @TyronBache Really impressed with @supabase&#x27;s Assistant. It has helped me troubleshoot and solve complex CORS Configuration issues on Pinger. @BowTiedQilin Working with @supabase has been one of the best dev experiences I&#x27;ve had lately. Incredibly easy to set up, great documentation, and so many fewer hoops to jump through than the competition. I definitely plan to use it on any and all future projects. @shadcn Supabase is really good. ⚡ @MinimEditor I’ve always used Supabase just as a database. Yesterday, I helped debug a founder’s vibe-coding project built with React + React Router — no backend server. The “backend” was entirely Supabase Edge Functions as the API. First time using Supabase this way. Impressive. @adm_lawson Love supabse edge functions. Cursor+Supabase+MCP+Docker desktop is all I need @Aliahsan_sfv Okay, I finally tried Supabase today and wow... why did I wait so long? 😅 Went from &#x27;how do I even start&#x27; to having auth + database + real-time updates working in like 20 minutes. Sometimes the hype is actually justified! #Supabase @orlandopedro_ Love @supabase custom domains makes the auth so much better @gokul_i First time running @supabase in local. It just works. Very good DX imo. @yatsiv_yuriy Supabase is the best product experience I&#x27;ve had in years. Not just tech - taste. From docs to latency to the URL structure that makes you think &quot;oh, that&#x27;s obvious&quot; Feels like every other platform should study how they built it @supabase I love you @sdusteric Loving #Supabase MCP. Claude Code would not only plan what data we should save but also figure out a migration script by checking what the schema looks like on Supabase via MCP. @dadooos_ Run supabase locally and just wow in silence! I am impressed! This is the kind of tooling I would want for my team. Open source from day one Supabase is built in the open because we believe great developer tools should be transparent, inspectable, and owned by the community. Read, contribute, self-host.

Track this score

Get this report by email, then a heads-up when supabase.com’s agent-readiness actually changes — a check regressing, or the composite dropping.

Two things never trigger an email: a score change caused by us publishing a new rubric, because that is a different instrument rather than a change to your site, and movement explained only by timing-derived checks, which shift run to run on a site nobody touched.

Want it on your own schedule, with Slack or a webhook instead of email? Score-drift monitoring is on every paid plan.

This score says whether an AI agent could read supabase.com. AI traffic analytics says whether one actually came — and which pages turned it away.
