TaleHall

In active development

Host any tabletop RPG campaign in the browser with instant-wake rooms, locked add-on versions, and optional virtual tabletop bridging.

TaleHall showing its instant-wake browser RPG room router and snapshot storage overview

Current status

Pre-release alpha universal RPG platform continuously bootstrapped by live Containment playtesting; supports native browser rooms or optional Bring-Your-Own-License Foundry bridging and gates prepaid compute credits behind alpha warnings.

Overview

Pre-release alpha tabletop RPG platform continuously bootstrapped by live Containment playtests—running system-agnostic campaigns directly in the browser on scale-to-zero Cloudflare Durable Objects and R2 storage without requiring Foundry VTT, while keeping an optional Bring-Your-Own-License container bridge and explicit alpha payment safeguards.

Why it was built

Game masters lose hours fixing broken add-ons before game night, while traditional cloud tabletop hosts charge round-the-clock volume fees for campaigns that are idle most of the week and lock creators into third-party software and rules licenses.

Why it helps

Pairs Containment's battle-tested browser HUD surfaces with instant-wake Cloudflare Durable Object rooms, low-cost R2 snapshot storage, self-hosted bare-metal container bridging, and a clean-room translation layer that graduates playtested campaigns to royalty-free first-party rules.

What you can do

VTT-independent browser stage supporting multiple RPG rulesets and clean-room first-party Threshold rules with zero third-party license fees
Multi-provider runtime router pairing scale-to-zero Cloudflare Durable Objects + R2 storage with self-hosted bare-metal Docker for optional BYOL Foundry worlds
Continuous anti-drift synchronization with Containment so live weekly campaign playtesting directly upgrades TaleHall's shared player and GM surfaces
Nano-USD credit ledger and Stripe checkout gated behind explicit pre-release alpha and BYOL acknowledgments

Pre-Release Alpha Notice — Not Product-Ready

TaleHall is in pre-release alpha. VTT-independent Cloudflare Durable Objects + R2 room hibernation (cloudflare_do), Helios bare-metal Docker bridges (helios_docker), clean-room First-Party IP Graduation (Threshold 2d10 Tactical Core), and nano-USD credit accounting are wired, while the Story Studio campaign builder remains in active development. All Stripe credit top-ups enforce an explicit Pre-Release Alpha acknowledgment gate.

TaleHall • Core Technology & Feature Architecture

VTT-Independent Universal RPG Engine & 4-Tier Cloudflare DO / Helios Runtime

Multi-system tabletop campaign platform combining scale-to-zero Cloudflare Durable Objects + R2 rooms, Helios bare-metal Docker BYOL bridges, and integer nano-USD credit metering.

Cloudflare DO + R2

Scale-to-Zero Native Browser Campaign Rooms (<50ms Wake)

Runs native browser RPG rooms on Cloudflare Durable Objects with WebSocket hibernation and content-addressed R2 storage ($0.015/GB-month) — cutting idle storage costs by 90% vs legacy VM volumes.

Helios Bare-Metal Bridge

Optional BYOL Foundry VTT Container Pool (AES-256-GCM)

Supports optional Bring-Your-Own-License (BYOL) Foundry VTT v14 container rooms on Helios bare-metal Docker with AES-256-GCM encrypted license vaulting and zero cloud VM markup.

6-System RPG Catalog

System-Agnostic Dice, Sheet & Encounter Descriptors

Provides unified descriptors for Threshold 2d10 Tactical Core, Containment UM5, 5e SRD, Pathfinder 2e Remaster, Blades in the Dark, and Call of Cthulhu d100.

Nano-USD Credit Ledger

Exact 10^9 Integer Metering & Pre-Release Alpha Gate

Meters compute and AI generation in integer nano-dollars (1 USD = 1,000,000,000 nanoUsd) with an explicit Pre-Release Alpha acknowledgment gate on all Stripe checkouts.

Comparison focus

Before: Pinned $0.15/GB-mo VM volumes running 24/7 for a 3-hour weekly game

Hosting campaign worlds on dedicated cloud VMs charges continuous compute and volume fees during the 165 hours a week no one is playing.

// Legacy per-world VM hosting

After: Cloudflare DO WebSocket hibernation (<50ms wake) + $0.015/GB-mo R2

TaleHall runs native browser RPG rooms on Cloudflare Durable Objects with WebSocket hibernation ($0 idle compute) and content-addressed R2 storage (90% cheaper per GB), plus optional Helios bare-metal Docker BYOL bridges.
