Building a Local-First AI, Audio, and Simulation Ecosystem as a Solo Developer

I’m Gary Doman / TizWildin, a solo developer and musician building a local-first open-source ecosystem across audio plugins, AI tooling, browser instruments, deterministic simulation, runtime dashboards, and experimental developer frameworks.

This post is the hub map for the projects I’m building.

The common thread is:

local-first
open-source foundation
receipt-backed systems
deterministic runtimes
audio + AI + simulation
tools that creators and developers can inspect

1. FreeEQ8 — free open-source JUCE EQ plugin

FreeEQ8 is a free open-source EQ plugin built with JUCE.

It is aimed at producers, engineers, and plugin developers who want a practical open EQ project to test, inspect, and improve.

2. Instrudio — browser instrument ecosystem

Instrudio is a browser-based virtual instrument ecosystem.

The flagship instrument is Studio Violin, a physically modelled bowed-string instrument using Helmholtz motion synthesis, H2 correction, Stradivari-style body EQ, sympathetic resonance, MIDI control, and a single-source-of-truth JSON instrument runtime.

3. ARC-Neuron LLMBuilder — local-first AI model lifecycle

ARC-Neuron LLMBuilder is a local-first AI model lifecycle framework.

It focuses on dataset-connected model growth, benchmark receipts, candidate/incumbent promotion, archive-ready lineage, and governed small-model improvement.

Repo:

https://github.com/GareBear99/arc-neuron-llmbuilder-v1.0.0

4. ARC-Core — authority, receipts, and event spine

ARC-Core is the authority/control-plane layer for the wider ARC ecosystem.

It is focused on receipts, event logging, replay/rollback, runtime state, governed actions, and evidence-backed system behavior.

Repo:

https://github.com/GareBear99/ARC-Core

5. ARC Language Module — governed multilingual backend

ARC Language Module is a governed multilingual backend.

It is not just a translator. It models language graph data, runtime routing, readiness, coverage reports, ingestion governance, FastAPI/CLI/SQLite surfaces, and evidence snapshots.

Repo:

https://github.com/GareBear99/arc-language-module

6. ARC-StreamMemory — AI-readable visual memory spine

ARC-StreamMemory turns visual sources into deterministic AI-readable memory modules.

It can work with video files, screenshots, screen recordings, robotics feeds, DAW/plugin sessions, game footage, and UI states.

The direction includes FFmpeg ingest, frame hashes, seeded source spines, AI digests, module attachments, ARC-style receipts, OmniBinary-style chunk maps, Arc-RAR-style bundle manifests, and local viewers.

Repo:

https://github.com/GareBear99/ARC-StreamMemory

7. Proto-Synth Grid Engine — math-first 2D world runtime

Proto-Synth Grid Engine is a deterministic, blueprint-driven, math-first simulation surface.

The idea is:

Geometry = storage
Movement = computation
Entities = executors

It uses deterministic 2D simulation projected into a visually 3D synth-grid interface.

Repo:

https://github.com/GareBear99/Proto-Synth_Grid_Engine

8. ARC Turbo OS — collapsing redundant computation

ARC Turbo OS is a seed-rooted deterministic runtime concept focused on canonical problem graphs, reusable subgraphs, branch-aware execution, ARC receipts, and end-state resolution.

The goal is not magic speed. The goal is to avoid recomputing work that has already been resolved safely.

Repo:

https://github.com/GareBear99/ARC-Turbo-OS

9. Seeded Universe Recreation Engine — deterministic universe timeline

Seeded Universe Recreation Engine is a deterministic seed-based universe simulator.

The project connects universe simulation, Synth Origin, Universe Bridge, ARC receipts, TT-101 doctrine, branch-comparable timelines, and seeded physics/life/civilisation experiments.

Repo:

https://github.com/GareBear99/Seeded-Universe-Recreation-Engine

10. Neo-VECTR Solar Sim NASA Standard

Neo-VECTR Solar Sim NASA Standard is the solar/planet simulation sibling direction.

It is part of the seeded simulation family, focused on solar-system simulation, planetary state, orbital structure, and NASA-style validation framing.

Repo:

https://github.com/GareBear99/Neo-VECTR_Solar_Sim_NASA_Standard

11. AI Desk Meter — local-first runtime dashboard toward MuseMeter

AI Desk Meter is an open-source local-first runtime dashboard.

It syncs with a JSON source of truth and is the open foundation leading toward MuseMeter, a future second-brain / Neural Synth / AI buddy product.

Repo:

https://github.com/GareBear99/ai-desk-meter

12. TT-101 Handbook — doctrine layer

TT-101 Handbook is the doctrine/canon layer for seeded universe handling, emergent life, communication ethics, intervention rules, and signal bridging.

Repo:

https://github.com/GareBear99/TT-101_Handbook

Why these projects connect

The ecosystem is built around a few shared principles:

• Local-first where possible
• Open-source foundation
• Deterministic state
• Receipts and audit trails
• Source-of-truth files
• Replayable memory
• AI-readable modules
• Lightweight runtimes
• Creative tools for musicians and developers
• Simulation systems that preserve lineage

The audio tools prove creative utility.

The AI tools build memory, language, evaluation, and runtime control.

The simulation tools test deterministic world/state ideas.

The dashboard tools make runtime state visible.

Together, they form one larger architecture.

Feedback welcome

I’m looking for feedback from:

• audio developers
• AI developers
• local-first software builders
• simulation developers
• game developers
• Web Audio developers
• Python developers
• JavaScript developers
• open-source maintainers
• people interested in deterministic runtimes and creative tools

This is a solo-dev ecosystem, built in public, with the goal of making useful creative tools and long-term local-first AI infrastructure.
