so one cron job function per day ? or one cron job for the whole account ?
It’s per cron job, not one cron job for your whole account.
As of Vercel’s current limits, the Hobby plan allows up to 100 cron jobs per project, and each individual cron job can run at most once per day. Vercel removed the old per-account Hobby limit of 2 cron jobs in January 2026. Vercel+1
So on one free Vercel project you could have, for example:
/api/cron/publish-posts → once daily
/api/cron/cleanup → once daily
/api/cron/send-digest → once daily
/api/cron/update-stats → once daily
/api/cron/check-expiry → once daily
Potentially up to 100 separate scheduled jobs, each firing once per day. Vercel
The restriction is that you cannot make one of those jobs run multiple times per day:
0 8 * * * ✅ once daily
0 14 * * * ✅ another cron, once daily
0 * * * * ❌ same cron runs hourly
*/15 * * * * ❌ every 15 minutes
So for your apps, the free tier is actually pretty generous if your scheduled work is daily. You could have 20 different daily automation functions in the same project without paying for Pro. The main catch is Hobby cron timing has approximately ±59 minutes precision, rather than firing at the exact minute. Vercel
can chatgpt sites have cron jobs?
Not natively, at least not currently during the ChatGPT Sites public beta.
OpenAI’s current Sites documentation does not expose a Cron Jobs or scheduled-functions feature. It specifically notes that some background services and hosting patterns are not supported by the Sites runtime. OpenAI Developers+1
There are two things that sound similar but are different:
FeatureChatGPT SitesVercelServer-side/API logic✅✅Persistent database✅ D1✅ external DB etc.File storage✅ R2✅Native cron scheduler**❌ Not currently documented/supported**✅HTTP/HTTPS endpoints✅✅Background scheduled processes⚠️ Limited/not supported✅
ChatGPT Sites itself is actually more capable than a purely static host. It can provision D1 relational storage up to 10 GB and R2 object storage, for example. OpenAI Developers But there isn't currently an equivalent of:
0 0 * * *
→ run /api/daily-task
Since Sites supports HTTP/HTTPS, you could potentially structure it like:
External scheduler
↓
https://your-chatgpt-site.com/api/cron
↓
Site server logic
↓
D1 database
So something external could hit an authenticated endpoint on the Site once per day. OpenAI confirms HTTP/HTTPS are supported by the Sites runtime. OpenAI Developers
There is also ChatGPT Scheduled Tasks, but that's a separate ChatGPT automation system rather than a cron service belonging to your deployed Site. Paid ChatGPT plans can currently run recurring Scheduled Tasks as frequently as once per hour. OpenAI Help Center
So for an actual SaaS/app where you need things like expire listings, publish scheduled posts, refresh statistics, process queues, or perform database cleanup, I would still consider:
Vercel + its cron → cleaner production architecture
while
ChatGPT Sites → great for lightweight apps where most actions happen from user requests
until OpenAI adds native scheduled/background jobs to Sites.
Yes. 100 cron jobs is a per-project limit, and Vercel explicitly removed the old per-team cron limits in January 2026. Vercel+1
So on Hobby:
Project A: up to 100 cron jobs
Project B: up to 100 cron jobs
Total across those two projects: 200 cron jobs
And Hobby accounts can currently have up to 200 projects, although all the normal account usage and anti-abuse limits still apply. Vercel
The important restriction remains that each Hobby cron schedule can run only once per day. So 200 cron definitions does not mean Vercel officially gives you a supported 200-times-per-day scheduler for one workload. Vercel
But purely from the documented limits: yes, 2 projects × 100 = 200 cron jobs.
what's the project limit in each vercel account ?
Currently, Vercel’s documented project limits are:
PlanProjectsHobby, free200 projectsProUnlimitedEnterprise****Unlimited
That 200-project Hobby limit applies to the Hobby account/team. Vercel
So in theory, on one Hobby account:
200 projects × 100 cron jobs per project = 20,000 cron definitions.
But that does not mean Vercel intends Hobby to be used as a 20,000-runs-per-day scheduler. You'd still be subject to the shared Hobby usage limits, including 1 million function invocations, 4 CPU-hours, 360 GB-hours provisioned memory, fair-use rules, and each cron definition being restricted to once daily. Vercel
One other useful detail: Vercel currently allows only one Hobby team per account. Vercel
So for your normal setup where each micro SaaS gets its own Vercel project, 200 is a pretty generous ceiling.
how do i check my limit usage
For Vercel, the easiest place is the team-level Usage page, not inside an individual project.
Go to your Vercel dashboard, select your Hobby team/account, then click Usage in the sidebar. Vercel shows your current allotment and consumption for things like function invocations, CPU, memory, Edge Requests, image optimization, and other resources. You can also filter the Usage page by a specific project to see which app is consuming the quota. Vercel+1
For Hobby, some useful limits to watch are currently:
ResourceHobby limitProjects200Cron jobs100 per projectFunction invocations1,000,000Active CPU4 CPU-hoursProvisioned memory360 GB-hoursEdge Requests1,000,000Deployments created100/day
One distinction: Usage does not necessarily give you a nice “37 / 200 projects” meter the way it does for compute usage. For project count, go back to the team's Projects page and look at your project list. The hard documented ceiling is 200 on Hobby. Vercel
And for cron jobs specifically, open:
Project → Settings → Cron Jobs
That will show the cron jobs configured for that particular project. Since the 100 limit is per project, you'd inspect each project's cron list separately.
If your concern is mainly whether you're getting close to exhausting the free Hobby resources, Usage → Function Invocations + Active CPU + Edge Requests are probably the three I'd watch most closely.
