Automated Let's Encrypt certificates
Once your domain is verified, SSL certificates are requested and installed automatically without manual ACME configuration.
Networking
Containers in a project communicate securely over an isolated internal network. Nothing touches the public internet until you explicitly open a port — complete with SSL, load balancing, and edge firewalls.

Traffic path
Public traffic terminates TLS at our regional edge proxy, clears firewall checks, and routes safely to exposed containers.
Project private network
Nothing exposed automatically
Newly deployed containers stay private until you deliberately map a public port.
Free SSL system subdomains
Every container instantly gets a secure default URL like <container>-<project>.<region>.hubfly.space.
Non-HTTP traffic support
Map dedicated public host ports for TCP/UDP traffic — ideal for databases, gRPC, and game servers.
Cloudflare proxy integration
Optionally proxy traffic through Cloudflare for additional DDoS protection.
Custom domains
Once verified, custom domains can attach to containers or load balancers with automated SSL certificates.
| Method | Key | How it works | Best for |
|---|---|---|---|
| DNS TXT record | dns_txt | A unique token set as a TXT record on your domain apex | Apex and wildcard domain verification |
| CNAME pointing | cname | Points directly to <project>.<region>.hubfly.space | Quick subdomain setup |
| HTTP file check | http_file | Serves a challenge file under /.well-known/hubfly-challenge/ | Domains backed by an existing web server |

Once your domain is verified, SSL certificates are requested and installed automatically without manual ACME configuration.
Issue wildcard certificates using ACME DNS-01 challenges so every subdomain is covered under a single cert.
*.yourdomain.com
Background workers auto-renew certificates 30 days prior to expiration, eliminating SSL downtime and calendar reminders.
Automatically redirect all incoming HTTP traffic to secure HTTPS with a simple toggle switch.
Load balancing
Group containers into load balancers, pick your routing algorithm, and set target weights for canary deployments.
| Algorithm | Key | Behaviour |
|---|---|---|
| Round robin | round_robin | Distribute incoming requests sequentially across healthy targets |
| Least connections | least_conn | Route requests to whichever target currently has the lowest active connections |
| IP hash | ip_hash | Hash client IP addresses for persistent, sticky session routing |

api-v190%api-v2 (canary)10%Health checks probe each target container. Failing instances are removed from the pool automatically until healthy.
HubTunnels
Tunnels multiplex up to 64 streams over a single encrypted WebSocket connection. Access is authenticated with short-lived tokens, keeping private databases hidden from public internet scans.
hubfly-cli
No public ports required
Connect to internal databases or microservices locally without opening public firewall ports.
Multi-container tunneling
Manage active tunnels to multiple project services simultaneously from our CLI or TUI.
Background daemon mode
Run local tunnels persistently in background daemon mode across restarts.
Edge proxy
Our edge proxy runs at the front of every region so caching, rate limiting, and threat filtering apply before traffic touches your app code.
Cached content is served instantly while edge nodes refresh assets in the background, keeping pages fast even if origin services lag.
Clear cached assets instantly by site, path pattern, or domain via dashboard or API with immediate global edge impact.
Block suspicious IP ranges outright or restrict internal admin tools to your corporate office network.
Protect sensitive API endpoints and authentication routes from brute force attacks using configurable rate limits.
If a backend service fails, edge circuit breakers trip and return 503 errors instantly, preventing cascading outages.
Every response includes a request ID and Server-Timing metadata, giving you complete visibility into proxy and backend latency.
