Companies Using Render

Everything on this page rests on one signal. Render is identified by a single response header, x-render-origin-server: Render, which comes back from the sites Render serves. As of our October 2026 crawl, TechnologyChecker.io sees that header on 8,749 live domains, with 5,616 of them matched to a company record. Two things decide how to read the list: most of its famous names are API documentation hubs run by ReadMe, and most of the sites leaving Render for Vercel belong to two hosted platforms.

What 8,749 counts

The 8,749 counts Render services with a public web address that our monthly crawl reached in October 2026. That leaves out a large part of what Render sells. Managed Postgres, background workers, cron jobs and private services have no public web surface, so a company running only those is invisible here. Cloudflare appears on 98.56% of Render domains because Render-hosted sites answer through Cloudflare's network; that is a property of the platform, not a choice 98.56% of customers made. Read 8,749 as a floor.

Sales Signal: a Render hit is a strong qualifier, because the header is specific to Render. A miss qualifies nothing.

Growth trajectory: five months of chart

Render's chart runs from 6,172 domains in June 2026 to 8,749 in October 2026. I wouldn't sell that as growth. The set of domains we crawl turns over every month, with dead sites dropping out and new ones added, and our detection widens over time. The count of domains where we have ever seen the header rose faster still, from 6,221 to 11,299, which is what wider coverage looks like. Exits are real too: 2,738 domains have stopped returning the header since we began tracking Render on 16 March 2026, and 1,657 of them now run on Vercel. Our records of Render go back to September 2020, before the chart starts.

"Render's chart went up, its exits went up and its ever-seen count went up faster than either. Three lines moving together at that speed are mostly about what we can see, so I'd quote the level and leave the slope alone." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales Signal: size Render as a list of 8,749 live sites, not as a fast-growing market. Time outreach off platform events, not off the chart's month-to-month steps.

Who is on the list: ReadMe's customers

42 of the 50 companies in our table appear through an API documentation hub built on ReadMe: techdocs.akamai.com, developers.asana.com, docs.gusto.com, developers.klaviyo.com, docs.jfrog.com, developer.ukg.com and so on. Every one loads ReadMe's assets and returns Render's header. Render's own ReadMe case study explains why: ReadMe moved its infrastructure from Heroku to Render and provides API documentation for "5000+ companies (including Akamai, Gusto, Scale AI, and Render)". In our 11 October 2026 check, 1,570 of the 9,267 domains live on Render ran ReadMe.

The eight exceptions are applications, and they are the more interesting rows. Evolve's partner portal (partner.evolve.com) runs on Render, and Render's Evolve case study says Evolve moved its frontends, web apps and APIs off 12 AWS accounts and cut infrastructure costs by 20%. Saritur sells coach tickets on viagens.saritur.com.br, the Labour Party runs its volunteer sign-up there, Lean Solutions Group an ROI calculator, Redington an AI exchange, and Fondazione Don Gnocchi its whole main website.

Sales Signal: for the 42 ReadMe rows, the buyer is a developer-relations or documentation team, and the vendor that picked Render was ReadMe. Don't pitch hosting to Akamai on the strength of techdocs.akamai.com.

Size, age and geography

Of the 5,510 Render companies with a known headcount in October 2026, 56.35% have 1 to 10 employees and 26.15% have 11 to 50. Only 73 have more than 1,000 staff. Founding years are young: 43.3% in the 2010s and 37.61% in the 2020s, 80.91% since 2010 in all. Software Development is the top industry at 16.56% (886 companies), then Technology, Information and Internet at 9.66% and Financial Services at 7.31%, the last mostly fintech API portals such as MoneyGram, Moneris and Pagbank.

By country, the United States has 2,288 matched Render companies, more than six times the United Kingdom's 363, with India (282), France (225), Canada (217) and Germany (188) behind. Nigeria (62) and Mexico (59) both make the top twelve.

Sales Signal: two motions. The 1 to 10 person layer buys self-serve and won't take a call; the companies above 1,000 staff will, but the person to reach usually owns a docs site.

Where Render sites go: Vercel, and who is moving

When a site stops returning Render's header, the platform it most often turns up on is Vercel. Since 16 March 2026, 1,657 domains moved from Render to Vercel and 83 moved the other way, about 20 to 1. 1,165 of the 1,657 moved in the 90 days to October 2026 and 89 in the last 30. The two-way test holds: of the 2,482 domains that ever ran both, only 672 (27.1%) still do, so the overlap resolved instead of persisting.

Then we opened the domains. A random sample of 40 sites that left Render for Vercel held 17 Hashnode blogs and 12 FunnelCockpit funnel pages; the FunnelCockpit ones had all switched on the same days, 8 to 13 August 2026. Across the whole corridor, 697 of the 1,657 domains are Hashnode blogs and 753 are FunnelCockpit pages. Those site owners didn't choose Vercel; their blogging and funnel platforms did. Roughly 200 domains remain, a mix of personal projects and small company sites.

"Twenty to one sounds like an exodus. Open the domains and it's two platforms, Hashnode and FunnelCockpit, moving their customers to Vercel in a few batches. The real churn to Vercel is the couple of hundred sites left after you take them out." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Nothing else in our data is a switch. Amazon Web Services shows 147 domains out and 90 in, but 1,403 of the 1,653 domains that ever ran both still do. Netlify (22 out, 36 in) and Fly.io (11 each way) trade evenly, and Heroku shows 2 domains out and none back.

Sales Signal: the Vercel list is two partnership stories, not 1,657 leads. For direct-account churn, filter out Hashnode and FunnelCockpit first and work the remaining couple of hundred.

The stack around Render

Across the 9,259 live Render domains in our October 2026 crawl, Next.js leads the front-end frameworks at 37.95%, then React Router (13.96%), React (8.12%), Vue.js (7.2%) and Nuxt.js (5.37%). On the server, Express is on 17.52% and Ruby on Rails on 9.59%, a real Rails cohort rather than noise. Google Analytics runs on 52.3%, Cloudflare Browser Insights on 8.08%, and the privacy-first tools Plausible (2.95%) and Umami (1.91%) appear in the tail, the kind of choice developers make when they deploy their own apps. Firebase shows up as a database on 2.18%.

Sales Signal: don't pitch these teams a platform. Pitch a component that sits behind what they already run, and assume the evaluator is the person who will install it.

Pricing and the free tier

Render's pricing page, checked 11 October 2026, lists four workspace plans: Hobby at $0 a month, Pro at $25, Scale at $499 and Enterprise at custom pricing, each plus compute. A web service runs from Free ($0, 512 MB of RAM) and $7 a month (512 MB, 0.5 CPU) upward. Render's free-tier docs say a Free web service spins down after 15 minutes without traffic and takes about one minute to start again, each workspace gets 750 Free instance hours a month, and Free Postgres databases expire after 30 days.

Sales Signal: a Render site on the free tier is a hobby or prototype by Render's own description. Qualify by company size before spending time on it.

What the reviews add

G2's Render sample is small. Ease of use leads the praise with 3 mentions; resource limitations (2 mentions) and price (1) lead the complaints. Read against the free-tier rules above, those are one complaint from two sides: the free and cheap tiers are small by design, and the step up is when a team asks whether it is on the right platform.

Key takeaways

1. One header, one floor. 8,749 live domains in October 2026; databases, workers and cron jobs are invisible.

2. The big names are ReadMe's customers. 42 of the 50 companies listed appear through ReadMe-hosted API docs.

3. Vercel is where sites go. 1,657 out against 83 back since March 2026.

4. But most of that is two platforms. 697 Hashnode blogs and 753 FunnelCockpit pages moved with their providers.

5. A small, young base. 56.35% of companies have 1 to 10 staff and 80.91% were founded since 2010.

Sales applications

Outreach template: "We noticed [Company]'s developer docs are served from Render through ReadMe. Are you happy with how your API reference performs, or looking at what else your developer portal needs?"

Targeting strategy: filter TechnologyChecker.io for Render, exclude ReadMe, Hashnode and FunnelCockpit, then keep Software Development and Financial Services companies with 11 to 200 employees. What's left is teams that chose Render themselves.

Competitive angle: the couple of hundred domains that left Render for Vercel on their own, outside the two platform moves, changed hosts this year and are the most open to a conversation about the rest of their stack.
