Deployment options

[michael]

Would still recommend Fly.io as the default, but https://github.com/hunvreus/devpush looks like a great alternative too. May be worth setting up and documenting.

Not a fan of serverless, but potentially the new https://void.cloud/ (with CloudFlare behind the scenes) might be something getting popular in the Svelte community.

The challenge here is read-after-write consistency because D1 writes and reads might have a delay due to syncing replicas across regions.

Deployment Platforms

Category	Fly.io	Koyeb	Nodion	Bunny.net
Type	Edge VM / PaaS	Serverless PaaS	PaaS	Edge platform (containers + scripting + DB)
Compute billing	Per-second VM billing (fly.io)	Per-second compute billing (Koyeb)	Per-second billing (Nodion)	Per-second CPU/RAM usage (docs.bunny.net)
Example instance (closest match)	2 vCPU / 2GB = $11.83/mo (fly.io)	2 vCPU / 8GB = $0.32/hr ($238/mo full) (Koyeb)	2 vCPU / 4GB = €20/mo (Nodion)	No fixed instance (usage-based CPU/RAM) (docs.bunny.net)
Autoscaling	Yes	Yes	Yes	Yes
Scale to zero	Supported (stop machines) (fly.io)	Supported (Koyeb)	Supported (per-second billing implies idle=0) (Nodion)	Not explicitly stated for containers
Database offering	External / managed Postgres	Serverless Postgres (scale-to-zero) (Koyeb)	Managed databases	SQLite-compatible (libSQL) (docs.bunny.net)
Edge compute (functions)	No (VM-based)	No (VM-based)	No	Yes (Edge Scripting billed per CPU time + requests) (docs.bunny.net)
Global deployment	Yes (multi-region)	Yes (multi-region) (Koyeb)	Yes	Yes (40+ regions) (docs.bunny.net)
Bandwidth pricing	$0.02/GB (EU) (fly.io)	100GB free, then $0.02/GB (Koyeb)	€0.02/GB (Nodion)	Usage-based (egress billed separately, CDN pricing applies) (docs.bunny.net)
Included bandwidth	None	100GB/month (Koyeb)	None	None
Storage pricing	$0.15/GB/month volumes (fly.io)	$0.50/GB/month (DB) (Koyeb)	€0.05/GB/month object storage (Nodion)	Separate (storage + DB billed by usage) (docs.bunny.net)
Cold start / idle cost	Stopped machines only pay storage (fly.io)	Scale-to-zero → no compute cost (Koyeb)	Per-second billing → no compute cost (Nodion)	Depends on usage (CPU/RAM billed only when used) (docs.bunny.net)
Pricing model clarity	Fixed presets + usage	Instance tiers + usage	Fixed instance tiers	Fully usage-based (no presets)

Normalized cost scenario

2 vCPU, 2GB RAM (closest match), 1TB egress, 10% usage (≈73h/month)

Cost component	Fly.io	Koyeb	Nodion	Bunny.net
Compute (full month equivalent)	$11.83 (fly.io)	$238.08 (2 vCPU / 8GB) (Koyeb)	€20 (2 vCPU / 4GB) (Nodion)	Not defined (usage-based) (docs.bunny.net)
Compute (10% usage)	$1.18	$23.81	€2.00	Depends on CPU seconds used (docs.bunny.net)
Bandwidth (1TB)	$20 (fly.io)	$18 (100GB free + 900GB × $0.02) (Koyeb)	€20 (Nodion)	Not fixed (egress billed separately) (docs.bunny.net)
Total monthly	≈ $21.18	≈ $41.81	≈ €22 (~$24)	Not computable from docs (no fixed CPU/RAM rates)
Idle cost behavior	Near-zero (stopped machines) (fly.io)	Zero (scale-to-zero) (Koyeb)	Zero (per-second billing) (Nodion)	Zero if no CPU/RAM usage (docs.bunny.net)

---

Notes:

• Bunny compute pricing cannot be converted to a monthly equivalent because it is billed per CPU-second actually consumed, not provisioned capacity. (docs.bunny.net)
• Koyeb does not offer a 2GB RAM / 2 vCPU tier; closest documented tier is 2 vCPU / 8GB. (Koyeb)
• All platforms bill egress separately except Koyeb (partial included). (Koyeb)

Nodion seems like a good alternative to Node. Potentially everything could be handled in one place. Including DNS, so there'd be just one place to set everything up.

They also waive invoices < 5€, so most sites would be hosted for free.
