Build your own ___.
The products you rent today — an app builder, a serverless database, a sandbox platform — are pools of VMs behind a load balancer with a nice interface on top. Heyo Web Services gives you the same pieces as open source, on hardware you own: Firecracker microVMs built from Dockerfiles, app-lb for routing, scaling, TLS and security, plus CI, observability and an MCP server so your agent can drive all of it. Here are three you can build this week.
Build your own Lovable
Describe the app, let your agent write it, and let
it ship it too. With the heyo MCP server connected,
your agent checks the deployment spec, calls
applb_deploy to build your Dockerfile
and roll it out, and hands you back a URL —
behind your own load balancer, with TLS, the SIEM
and observability already on.
# Give your agent the heyo MCP server claude mcp add heyo \ -e HEYO_API_KEY=heyo_api_… \ -- node /path/to/hws/mcp/dist/index.js # Then ask for what you want > Build ./Dockerfile and ship it at shop.example.com
Build your own Neon
Serverless Postgres, on your metal. pg-fc runs one
Firecracker microVM per database behind a single
pooler on :6432. Connect with a new
database name and its VM is created; leave it idle
and it stops, moving to cheaper storage tiers until
the next client connects.
# The dbname picks the database — and its VM psql "host=127.0.0.1 port=6432 user=postgres dbname=tenant1" # -> VM pg-tenant1 psql "host=127.0.0.1 port=6432 user=postgres dbname=tenant2" # -> VM pg-tenant2
Build your own Daytona
Sandboxes for your agents are just deployments with
no public route. Create one, run commands in it,
open a shell, keep it around or let it sleep, and
expose it on a hostname when there is something to
show — from the heyctl CLI, the
hws Rust crate, or your agent over
MCP.
# An agent sandbox, start to finish heyctl create deployment sb-7f3a9c --no-route --port 8080 --size medium --disk-gb 8 heyctl scale sb-7f3a9c --idle-action retain heyctl exec sb-7f3a9c --cwd /workspace -- git status heyctl set route sb-7f3a9c --host sb-7f3a9c.example.com # expose it later
Build your own cloud
Open source, on hardware you own, driven from your agent. Pick a case and start.
