On GCP and Azure, most folks would be better off running serverless containers via Cloud Run or Container Apps (AWS has no direct equivalent that scales to 0 and incurs no cost).
Both of these scale to zero and offer 180k vCPU/s free per month, 360k GB/s free per month. You incur billing only against the active execution time. Cloud Run Jobs has a whole separate free monthly grant as well.
You can run A LOT for free within those constraints. Certainly a blog or website. To prevent cold starts, just set up Cloud Scheduler (also free for this purpose) to ping the container every few minutes.
Use Supabase for a DB or one of the serverless options (if it works for your data use case) like Firestore, CosmosDB and you can run workloads for a few cents per month with an architecture that will scale easily if you need it to.
