# Temps vs Fly.io

> Fly.io has no free tier and no monthly fee: it is pay-as-you-go from $2.19/month, since its plans were discontinued on October 7, 2024. Every Fly app runs as a container image deployed with the flyctl CLI; there is no native git-push. Temps is the self-hosted Fly.io alternative: free on your own server, with native git-push deploys (no Dockerfile required) and built-in analytics, error tracking, session replay and uptime monitoring. Fly.io runs in 17 regions; Temps runs where your servers are.

Fly.io runs your app near users. Temps runs it on your servers.

## Short answer

Fly.io has no free tier and no monthly platform fee: new organizations pay as they go, from $2.19/month for the smallest always-on Machine. Fly's own example of a small app with Managed Postgres is about $44/month, and adding Sentry Team, Plausible and LogRocket (about $211/month) takes it to roughly $255/month. Temps is free and self-hosted, with the four observability tools in the binary and databases on the same machine, so the cost is the machine. What Fly.io has that Temps doesn't: Things a single VPS cannot do: 17 regions with Anycast routing, and Firecracker Machines that auto-stop when idle so you pay only while they run.

## TL;DR

| Dimension | Temps | Fly.io | Better fit |
| --- | --- | --- | --- |
| Free tier | Free forever, self-hosted | Discontinued Oct 2024 | Temps |
| Cost, full stack + observability | Free (included) + your server | ~$255/mo | Temps |
| Global region coverage | Wherever your servers are | 17 regions, edge-native | Fly.io |
| Scale-to-idle compute | Long-running containers | Firecracker Machines that auto-stop when idle | Fly.io |
| Docker-based deploys | Yes | Yes | Tie |

## Key differences

- **Fly.io: no free tier, no monthly fee — pure pay-as-you-go:** Fly.io discontinued its free allowances and sold plans (Hobby, Launch, Scale) on October 7, 2024. New organizations are pay-as-you-go with no monthly platform fee; the only free thing is a trial of $1 in credit that lasts 7 days or until it's used up, whichever comes first. The smallest always-on Machine is $2.19/mo, and billing is per second for what runs. Temps is MIT / Apache 2.0 — self-host free on any VPS you provide.
- **Native git-push vs CLI-driven deploys:** Fly.io deploys through the flyctl CLI ('fly launch' can generate a Dockerfile for common frameworks); git-push workflows require wiring up GitHub Actions. Temps deploys on every git push out of the box, autodetecting your framework with no CI configuration.
- **Full observability built in:** Fly.io provides Prometheus metrics but has no error tracking, session replay, or analytics. Temps ships Sentry-compatible error tracking, privacy-first analytics, rrweb-based session replay, and 60-second uptime monitoring — all in the same binary as the deployment engine.
- **Self-hostable with Pingora:** Fly.io is cloud-only. Temps is MIT / Apache 2.0 — install on any server. Temps uses Pingora (Cloudflare's open-source Rust proxy, handling over 1 trillion requests per day) for routing, and worker nodes join one control plane over a private network you provide.

## Pricing

| Item | Temps | Fly.io |
| --- | --- | --- |
| Free / getting started | $0 (self-hosted, MIT / Apache 2.0) | None — only a $1 / 7-day trial |
| Entry paid | Free — your own VPS | From $2.19/mo (smallest always-on Machine, pay as you go) |
| App + DB + Redis | Your own VPS (all included) | ~$44/mo (Fly's example: app + Managed Postgres), plus Redis via Upstash |

Fly.io has no free tier and no monthly platform fee. Machines are billed per second, from $2.19/month for the smallest always-on size in the cheapest regions, plus volumes, bandwidth and any managed database. A Temps server costs only the server, with databases, monitoring, analytics and error tracking included. Every Fly.io rate is in the Fly.io pricing guide under Further reading.

## Choose Temps if

- You want native git-push deploys with no Dockerfile required
- You need built-in analytics, error tracking, session replay, and uptime monitoring
- You prefer flat predictable pricing with no per-second billing
- You need self-hosting for compliance, data sovereignty, or vendor lock-in avoidance
- You want managed databases and email included, not billed separately

## Choose Fly.io if

- You need Anycast edge deployment across 17 regions
- You want Firecracker Machines that auto-stop when idle and start on request
- You want managed Postgres with automatic failover on the same platform (from $38/mo)
- You prefer granular pay-per-second billing for bursty, low-traffic apps
- You want the longer track record: Temps is pre-1.0 (v0.1.0 prereleases), newer and smaller, which is also why it bundles the observability Fly.io leaves to other vendors

## Migrating from Fly.io (easy)

Fly.io apps are container images, so they deploy unchanged on Temps, and fly.toml settings map to Temps project settings. Re-create secrets in Temps (import them with `bunx @temps-sdk/cli environments vars import .env`), move Postgres with pg_dump and restore into a Temps-managed service, and move Upstash Redis with DUMP/RESTORE. Fly volumes have no direct equivalent for app containers: move that data to managed Postgres or S3, or use a Docker Compose project with named volumes. Machines in several regions become Temps worker nodes joined over a private network you provide (a VPC, VPN or Tailscale). Most apps move in an afternoon.

## FAQ

### Does Fly.io have a free tier in 2026?

No. New Fly.io organizations have no free tier and no monthly free allowance. They get a free trial of $1 in credit that lasts 7 days or until it's used up, whichever comes first, and need a credit card after that. Fly.io stopped selling plans and free allowances on October 7, 2024. Source: fly.io/docs/about/pricing.

### How much does Fly.io cost in 2026?

Fly.io has no monthly platform fee — you pay for what you use. The smallest always-on Machine is $2.19/mo, Managed Postgres starts at $38/mo, volumes are $0.15/GB/mo, and outbound data is $0.02/GB in North America and Europe. Fly's own example of a small web app with Managed Postgres comes to about $44/mo. The old Hobby, Launch and Scale plans were discontinued on October 7, 2024; optional support is $29/mo (Standard) or $199/mo (Premium).

### Does Fly.io require Docker?

Every Fly.io app deploys as a container image, but you don't have to write the Dockerfile yourself — 'fly launch' can generate one for common frameworks. There is no native git-push workflow: deploys go through the flyctl CLI, and continuous deployment requires wiring up GitHub Actions. Temps deploys on git push out of the box, autodetecting Next.js, Vite, Python, Go, Rust and Java apps without a Dockerfile (Ruby, PHP and plain Node.js servers use a preset you choose).

### What are the best Fly.io alternatives in 2026?

The top Fly.io alternatives in 2026 are Temps (self-hostable, built-in observability, free), Railway (usage-based), Render (flat workspace plans), and self-hosted options such as Coolify and Dokploy. Temps is the only one that's self-hostable under MIT / Apache 2.0 and includes error tracking, analytics, session replay, and uptime monitoring at no extra cost.

### What is Temps' reverse proxy — how does it compare to Fly.io?

Temps uses Pingora, the open-source Rust reverse proxy Cloudflare built to replace Nginx across its global network. Pingora handles over 1 trillion requests per day on Cloudflare's infrastructure. Fly.io uses a managed Anycast-based proxy. Temps embeds Pingora directly — no separate proxy container, no extra configuration.

### How does Temps handle multi-node deployments compared to Fly.io?

Fly.io distributes workloads across 17 regions via Firecracker VMs and Anycast routing. Temps adds worker nodes to one control plane with `temps join` over a private network you provide (a VPC, VPN or Tailscale), authenticated with mTLS, and schedules apps across them. You can run multi-server clusters on any VPS provider; Temps has no Anycast routing or built-in multi-region network.
