Mailpit Pricing: Managed vs Self-Hosted
The cheapest managed Mailpit starts at about $14/month. Self-hosted, this stack measures 256 MiB across 1 service, which fits a $5/month flat plan with room left over.
#the numbers
Managed prices as of June 2026, each linked to its source. The self-hosted row is not an estimate: the RAM figure is what this stack allocates in its compose file, and the plan is the smallest one that holds it.
| Option | Plan | Monthly | What you get |
|---|---|---|---|
| Self-hosted on Miget ★ | 512 MiB, 1 vCPU | $5 | the whole stack, flat - no per-user or per-request metering, and the plan holds your other apps too |
| Mailtrap | Testing Basic | ~$14 | ~500 test emails/mo in the sandbox product - the exact job Mailpit does unmetered |
#the difference, plainly
$9/month, or about 64%, against the cheapest managed tier - $108 over a year. Worth stating what that money buys and what it costs, because the honest answer is not "it is just cheaper".
- You gain a bill that does not move with usage, no execution or seat metering, and root on your own data.
- You gain spare capacity: the plan is sized for this stack, and anything else you deploy inside it is free.
- You take on upgrades, backups and the pager. Managed services charge for exactly that, and for some teams it is worth every dollar.
- You should not switch for the saving alone if your team has nobody who wants to own it.
#what it costs on other platforms
Same stack, published rates elsewhere - estimates from each platform's own pricing page, not quotes.
| Platform | Estimated monthly | Why |
|---|---|---|
| Miget ★ | $5 | flat plan, 512 MiB - databases included, no meters |
| Heroku | ~$13 | no volumes; nothing between 1 GB ($50) and 2.5 GB ($250) dynos - 2 GB containers cost far more than shown |
| DO App Platform | ~$10 | no persistent volumes - stateful containers need managed DBs/Spaces (base $5 Spaces included here) |
| Render | ~$7 | per-service instances (0.5 GB $7, 2 GB $25) - every container is its own paid service |
| Railway | ~$3 | usage-based ($10/GB RAM-mo); vCPU billed separately at $20/vCPU-mo on top |
| Fly.io | ~$2 | cheapest sticker price - but burstable shared CPUs (1/16 core; dedicated vCPUs cost ~2-3×), no compose deploys (one app per container, manual wiring), managed DBs billed extra |
#sizing, if you outgrow the small plan
The $5 plan is the smallest that fits. For production traffic you generally want the next tier up, and dedicated vCPU if the workload is CPU-bound rather than idle-waiting.
| Use case | Plan | Monthly |
|---|---|---|
| Fits the stack | 512 MiB, 1 vCPU shared | $5 |
| Comfortable, room for your own apps | 1 GiB, 1 vCPU shared | $7 |
| Dedicated vCPU (production) | 2 GiB, 1 vCPU dedicated | $22 |
A single Go binary that idles around 30 MB - 256 MiB is generous. The 5,000-message cap keeps the volume tiny.
Run Mailpit yourself
The compose file is open source and runs locally with docker compose up. One step to deploy it to
Miget on the $5/month plan, databases included.
