Backyard AI is the pick for readers who want AI character chat and roleplay running on their own machine without configuring a frontend. The free desktop app for Windows and Mac needs no account, no credit card, and no manual setup of backends like koboldcpp or text-generation-webui β€” install it, pick a character from the built-in Character Hub or a community roleplay model like Fimbulvetr 10.7B, and start chatting entirely offline. Readers without a capable GPU can pay for Backyard Cloud ($7–$35/month) to run larger hosted models instead. Readers who want deep prompt-template control, group chats, or a fully open-source stack should compare it with SillyTavern or Loci AI.

Backyard AI (backyard.ai), formerly named Faraday.dev, is a free, closed-source desktop app for Windows and Mac built specifically for AI character chat and roleplay. It runs open-source models β€” Llama, Mistral, Gemma, and community-tuned roleplay fine-tunes such as Fimbulvetr 10.7B β€” entirely on your own hardware, with no account and no credit card required for local use. Its Character Hub gives you thousands of user-created personas to chat with out of the box, and an optional paid Backyard Cloud tier adds hosted inference for readers without a capable local GPU. The practical question is not whether local roleplay is possible β€” SillyTavern and RisuAI already prove that β€” it is whether Backyard AI's point-and-click simplicity is worth its closed-source model and curated character library compared with the more open, more configurable frontends covered elsewhere on this site.

Backyard AI Review (2026): Local AI Character Chat and Roleplay

Key Takeaways

  • Backyard AI (backyard.ai), formerly Faraday.dev, is a free, closed-source desktop app for Windows and Mac focused on AI character chat and roleplay.
  • Local mode is free, needs no account, and runs entirely offline once a model is downloaded β€” models include Llama, Mistral, Gemma, and community roleplay fine-tunes like Fimbulvetr 10.7B.
  • Character Hub is the standout feature: thousands of pre-built, user-created AI characters and personas, ready to chat with immediately.
  • Optional Backyard Cloud tiers (Free/$7/$18/$35 per month) add hosted inference on larger models β€” Midnight Rose 70B and Magnum 72B on the Pro tier β€” for readers without a strong local GPU, plus mobile and web access that syncs with desktop.
  • Hardware guidance: Fimbulvetr 10.7B and similar 8B–13B roleplay merges run comfortably on a 16 GB VRAM gaming GPU; the largest community models want 24 GB+ VRAM or 36 GB+ unified memory on Apple Silicon.
  • Backyard AI trades customization for simplicity: no group chats, no open-source frontend code, and a curated (not unlimited) local model list, compared with SillyTavern.
  • The referral program pays account bill credit for referrals, not cash commission β€” do not confuse it with a traditional affiliate program.

What Backyard AI Is

Backyard AI is a desktop application, formerly named Faraday.dev, built by a small independent team around one goal: making local AI character chat and roleplay approachable for readers who do not want to assemble a backend (koboldcpp, text-generation-webui, Ollama) and a separate frontend (SillyTavern, Agnai, RisuAI) themselves.

The app is free and closed-source β€” unlike SillyTavern, RisuAI, or Agnai, the frontend code is not published for community audit or modification. In local mode it needs no account, no credit card, and no internet connection once a model is downloaded.

Its centerpiece feature is the Character Hub: a built-in library of thousands of user-created AI characters and personas. Instead of writing a character card from scratch (the standard SillyTavern workflow), most readers start by browsing the Hub and picking one that already fits the kind of conversation or story they want.

Local mode supports voice interaction alongside text chat, and advanced settings expose lorebooks, author's notes, custom context size, sampler settings, and grammars for readers who want more control once they are comfortable with the basics.

πŸ“ In One Sentence

Backyard AI is a free, closed-source desktop app for Windows and Mac that runs open-source LLMs locally for AI character chat and roleplay, with an optional paid cloud tier for hosted inference.

πŸ’¬ In Plain Terms

Think of it as a roleplay-focused alternative to Ollama plus a chat interface, pre-packaged with thousands of ready-made characters β€” you skip the backend/frontend split that SillyTavern requires.

How Local Mode Works

Local mode is the free, offline path: install the app, download a model, and chat without sending anything to a server.

  • Model selection. Backyard AI ships with a curated set of open-source models optimized for character chat β€” Llama and Mistral base models, Gemma variants, and community roleplay fine-tunes such as Fimbulvetr 10.7B, which was built specifically for character consistency and narrative voice rather than general assistant tasks.
  • No account required. Local chat works without signing up, entering payment details, or connecting to Backyard Cloud. Everything runs and stays on the machine you installed the app on.
  • Character Hub browsing. Pick a pre-built character card from the Hub, or import/write your own β€” the same underlying local model powers every character, but the character card supplies personality, backstory, and tone.
  • Advanced controls when you want them. Lorebooks (persistent world/character facts injected into context), author's notes (steering instructions), custom context window size, sampler settings (temperature, top-p, repetition penalty), and grammars (structured output constraints) are all available in local mode without needing Backyard Cloud.
  • Tethering to a desktop. Readers running Backyard AI on a phone or lighter machine can tether to a more powerful desktop running the full app, offloading inference to that machine while keeping the chat interface on the lighter device.

Trade-Offs: Benefits vs. Limitations

Free local mode, no account

What it means in real use:
Download the app and a model, then chat offline indefinitely at no cost.
Limitation / caveat:
Larger/newer models beyond the curated local list require Backyard Cloud instead.

Character Hub

What it means in real use:
Thousands of ready-made AI characters β€” no need to write a character card to start chatting.
Limitation / caveat:
Quality of community-submitted characters varies; curation is uneven compared to a hand-picked set.

Minimal setup

What it means in real use:
One installer, no separate backend/frontend pairing to configure, unlike SillyTavern.
Limitation / caveat:
Less transparency into what is running under the hood since the app is closed-source.

Local privacy

What it means in real use:
Local-mode conversations are processed on-device; nothing is sent to Backyard Cloud unless you opt in.
Limitation / caveat:
Closed-source code means the privacy claim cannot be independently verified the way an open-source frontend can.

Optional cloud scaling

What it means in real use:
Backyard Cloud lets readers without a strong GPU run 70B-class models (Midnight Rose 70B, Magnum 72B) from any device.
Limitation / caveat:
Cloud tiers cost $7–$35/month and conversations on cloud models are processed on Backyard's servers, not locally.

Advanced controls available locally

What it means in real use:
Lorebooks, author's notes, custom context size, sampler settings, and grammars work without a subscription.
Limitation / caveat:
No group chats and no visual node-based workflow editor β€” SillyTavern extensions go further for power users.

Cross-device continuity (cloud)

What it means in real use:
Backyard Cloud syncs the same characters and chats across desktop, web, iOS, and Android.
Limitation / caveat:
This convenience only applies to the paid cloud tiers, not to fully offline local-mode chat.

Community roleplay fine-tunes

What it means in real use:
Fimbulvetr 10.7B and similar merges are tuned specifically for character voice consistency, not generic assistant behavior.
Limitation / caveat:
These merges reason less reliably than larger frontier or general-purpose instruction models.

Backyard Cloud Pricing

Backyard Cloud is optional β€” local mode covers chat for free indefinitely. Cloud tiers exist for readers who want larger hosted models or cross-device sync without owning a capable GPU.

Backyard Cloud runs a referral program, not a cash-commission affiliate program: referring a friend gives them 50% off their first month, and gives the referrer promotional bill credit (roughly $17.50 per Pro referral, $9.00 per Advanced, $3.50 per Standard) applied to their own account β€” not a cash payout. Pricing verified against backyard.ai on 2026-09-02; confirm current tiers before subscribing since SaaS pricing changes.

Backyard AI on Windows and Mac

Windows

What to expect:
Free installer from backyard.ai. Local inference uses your GPU (NVIDIA CUDA) or CPU/RAM depending on hardware. Full Character Hub and local model library available.
Important note:
A 16 GB VRAM gaming GPU comfortably runs Fimbulvetr 10.7B-class models; CPU-only setups work but respond slower.

Mac

What to expect:
Native app for Apple Silicon. Unified memory lets larger community models run without a discrete GPU, similar to how Ollama and LM Studio use Apple Silicon.
Important note:
36 GB+ unified memory gives headroom for the larger community roleplay merges; base 8–16 GB Macs are limited to smaller models.

Mobile & web (Backyard Cloud only)

What to expect:
iOS, Android, and web apps connect to Backyard Cloud for hosted inference and sync the same characters and chat history with desktop.
Important note:
Mobile/web access requires a Backyard Cloud plan (Free tier included) β€” there is no offline local-inference mode on phone.

Who Should Use Backyard AI

  • Reader new to local AI roleplay. Backyard AI removes the backend/frontend split entirely β€” one installer, one app, immediate access to the Character Hub. This is the easiest on-ramp into local character chat covered on this site.
  • Reader who wants ready-made characters. Browsing thousands of pre-built personas in the Character Hub beats writing a character card from scratch, especially for a first session.
  • Reader without a strong GPU who still wants larger models. Backyard Cloud's Standard/Advanced/Pro tiers give access to 70B-class models (Midnight Rose 70B, Magnum 72B) without buying hardware.
  • Reader who wants cross-device continuity. Backyard Cloud syncs chats and characters across desktop, web, iOS, and Android β€” useful for continuing a conversation started on a PC from a phone.
  • Reader who values simplicity over deep configuration. Lorebooks, author's notes, and sampler settings are available without needing to learn SillyTavern's extension ecosystem.
  • Privacy-conscious reader on a budget. Local mode is free, needs no account, and keeps conversations on-device β€” a reasonable middle ground between a fully cloud service and a fully DIY open-source stack.

Who Should Not Use Backyard AI

  • Reader who wants an auditable, fully open-source frontend. Backyard AI's app code is closed-source. Readers who need to verify exactly what the app does with their data, or who want to modify the frontend, should use SillyTavern or RisuAI instead.
  • Reader who needs group chats or advanced prompt templating. SillyTavern's extension ecosystem covers multi-character group scenes and deep prompt-template control that Backyard AI does not offer.
  • Reader who wants unlimited model choice locally. Backyard AI's local model list is curated; it does not support importing any arbitrary GGUF file the way SillyTavern-plus-koboldcpp does.
  • Reader unwilling to pay for larger hosted models. The free local models are capped around the 8B–13B range; reaching Midnight Rose 70B or Magnum 72B quality requires a paid Backyard Cloud subscription.
  • Reader who needs the deepest model-management control, quantization tuning, or benchmarking. More technical local-LLM tools give finer control over quantization formats and inference parameters than Backyard AI's simplified interface exposes.

Frequently Asked Questions

Is Backyard AI free?

Yes, for local mode. The desktop app for Windows and Mac is free to download, needs no account or credit card, and lets you chat with locally downloaded models offline at no cost. Backyard Cloud, the optional hosted tier for larger models and mobile/web access, has a free plan plus three paid tiers: Standard ($7/month), Advanced ($18/month), and Pro ($35/month).

What was Backyard AI called before?

Backyard AI was previously named Faraday.dev. The app was rebranded to Backyard AI; the underlying local-first character-chat concept is the same.

Is Backyard AI open source?

No. Backyard AI is closed-source, unlike SillyTavern, RisuAI, and Agnai, which publish their frontend code for community audit and modification. Local-mode chat still runs entirely on your device, but the app itself is not open for inspection.

What is the Character Hub?

The Character Hub is Backyard AI's built-in library of thousands of user-created AI characters and personas. Instead of writing a character card from scratch, most readers browse the Hub and pick one that fits the conversation or story they want, then chat with it using a locally downloaded model.

What hardware do I need to run Backyard AI locally?

Fimbulvetr 10.7B and similar 8B–13B roleplay-tuned models run comfortably on a 16 GB VRAM gaming GPU. The largest community models available in Backyard Cloud (Midnight Rose 70B, Magnum 72B) need roughly the same VRAM tier as any 70B-class local model β€” around 42 GB VRAM at Q4_K_M β€” or 36 GB+ unified memory on Apple Silicon; for local (non-cloud) use, stick to the 8B–13B tier unless your hardware matches that ceiling.

Does Backyard AI work offline?

Yes, in local mode. Once the app and a model are downloaded, chat runs entirely on-device with no internet connection required. Backyard Cloud, mobile apps, and web access require an internet connection since inference happens on Backyard's servers.

Is the Backyard Cloud referral program a paid affiliate program?

No. Referring a friend gives them 50% off their first month and gives the referrer promotional bill credit toward their own subscription β€” roughly $17.50 for a Pro referral, $9.00 for Advanced, and $3.50 for Standard. This is account credit, not a cash commission payout.

How does Backyard AI compare to SillyTavern?

Backyard AI trades customization for simplicity: one installer, a built-in Character Hub, and no separate backend to configure, but a closed-source app with no group chats. SillyTavern is fully open source, supports group chats and deep prompt-template customization via extensions, but requires pairing it with a separate backend (koboldcpp, text-generation-webui, or Ollama) and has a steeper learning curve. See the full comparison in SillyTavern vs. Agnai vs. RisuAI.

Can I import my own character cards or models into Backyard AI?

You can import or write your own character cards for use with any locally downloaded model. Model selection for local mode is limited to Backyard AI's curated list (Llama, Mistral, Gemma variants, and roleplay fine-tunes like Fimbulvetr 10.7B) β€” it does not support importing an arbitrary GGUF file the way a koboldcpp-plus-SillyTavern setup does.

Does Backyard AI support voice interaction?

Yes. Local mode includes voice interaction alongside text chat, in addition to advanced settings like lorebooks, author's notes, custom context size, sampler settings, and grammars.

Verdict

Backyard AI earns its place as the lowest-friction entry point into local AI character chat covered on this site. The combination of a free desktop app, no account requirement, and a Character Hub stocked with thousands of ready-made personas removes the two biggest barriers to trying local roleplay: backend configuration and character-card writing. For readers who outgrow the local model ceiling, Backyard Cloud's $7–$35/month tiers scale up to 70B-class models (Midnight Rose 70B, Magnum 72B) without requiring a hardware upgrade, and the referral program pays account credit rather than cash β€” worth knowing so expectations are set correctly. The trade-off is real: the app is closed-source, offers no group chats, and limits local model choice to a curated list, so readers who want an auditable, fully open, deeply customizable stack should use SillyTavern instead. For everyone else who wants roleplay working in minutes rather than hours, Backyard AI is a strong first stop.
