Crabtalk
Crabtalk is an open-source agent runtime for running coding agents on plain files, paired with the Cydonia desktop workspace.
If you already run coding agents and want sessions, a gateway and durable files without a SaaS vendor between you and the output, assess CrabTalk on the four repos themselves — they're open source, and you can try them before a dollar changes hands. Budget for assembly time: these are four projects, not one product. Skip it if you needed the retired Studio's news radar and board/calendar projects, because that app is archived.

Skip Crabtalk if you want a single integrated app — this is four separate open-source projects (Cydonia, Bezel, CrabLLM, the daemon) you install and wire together yourself.
Running the daemon always-on means you supply the always-on machine — a laptop that sleeps is not a runtime.
For developers self-hosting agent tooling, Crabtalk's cost is mostly your own infrastructure plus whatever model provider you connect; the preserved Hobby and Go pages describe a retired product, so treat any archived $0/$8 split as historical rather than a current offer to subscribe to.

What is Crabtalk?
Crabtalk — Crabtalk is an open-source agent runtime for running coding agents on plain files, paired with the Cydonia desktop workspace. Best for Rust and systems developers building agent tooling they self-host, Teams wanting one LLM gateway binary in front of OpenAI, Anthropic and Ollama, Developers who need agent output as plain files on disk instead of a proprietary store. Free to start; paid plans from $8/mo.
Crabtalk ships four open-source projects you assemble yourself. Cydonia is the front door: a desktop workspace for coding agents where you open a directory as a project, write, and drive ACP-compatible agents while output stays as ordinary files on disk. Bezel is a Rust UI component library with a SwiftUI-inspired GPUI API and shared theming. CrabLLM puts OpenAI, Anthropic and Ollama behind one endpoint with routing, failover and budget controls. And the CrabTalk daemon is the always-on runtime that manages independent agent sessions and streams events to whatever client connects. Install is a shell command on macOS, Linux or Windows, or `cargo install crabtalk` from source. Docs cover agents, sessions, cron, events, skills, memory and MCP servers. Skills are Markdown files with YAML frontmatter that every agent on your install can pick up. The vendor page is explicit that the old desktop Studio app is retired; its original product pages are archived for reference only. The live line-up is Cydonia, Bezel, CrabLLM and the daemon. Pricing on crabtalk.ai/pricing lists Hobby at $0 and Go at $8/month, with Go framed around the engine rather than the app: you bring the agent engine on Hobby, we run the models on Go. It's a developer toolkit first — teams replacing a hosted agent runtime or a managed Ollama wrapper are the intended audience, not content marketers.
Key features
- Cydonia desktop workspace: open a directory as a project
- Works with ACP-compatible coding agents you already run
- Output kept as durable files on disk, not a proprietary store
- Bezel: Rust component library with SwiftUI-inspired GPUI API
- Shared themes carry style through a Bezel-built app
- CrabLLM: single-binary LLM gateway with routing and failover
- CrabLLM routes to OpenAI, Anthropic and Ollama from one endpoint
- CrabLLM budget management through one endpoint
- CrabTalk daemon: always-on runtime for independent agent sessions
- Session events streamed to the connected client as they happen
- Guests over MCP in the Cydonia workspace
- One-command install via curl on macOS, Linux and Windows
- Build from source with Cargo (cargo install crabtalk)
- Custom skills authored as Markdown with YAML frontmatter, shared across every agent
- Docs covering agents, sessions, cron, events, skills, memory, MCP servers
Behind the verdict
Reach for CrabTalk when the thing you actually want is control over the runtime. The daemon model — an always-on process holding independent sessions and streaming events back — is the right shape for teams running several agents in parallel and wanting each one's output on disk where git can see it. CrabLLM earns its place separately: one binary in front of OpenAI, Anthropic and Ollama with failover and budget limits solves a problem most teams hit around their third provider. Where it bites is assembly. Four repos mean four sets of docs, four version pins and four chances to spend an afternoon on glue instead of product. If you want one integrated app with a support contract, this isn't that, and no amount of `cargo install` changes it. The closest alternative changes with your goal: hosted agent runtimes like LangSmith give you observability without self-hosting, while a plain Ollama setup plus a shell script gets you 80% of the gateway for none of the binary. On money: the pricing page lists Hobby at $0 and Go at $8/month, and the split is the engine. Hobby assumes you already pay for a coding agent engine; Go means CrabTalk runs the models under a monthly allowance that pauses inference when spent rather than billing overage. Confirm current terms on the pricing page yourself before committing, since the page and the archived Studio marketing copy disagree in places. The archived Studio is the trap. News radar, media kinds, board/calendar/map projects — all retired, preserved only as reference pages. If a search landed you on that copy, you're reading about a product that no longer exists. In practice, the sweet spot is a small engineering team that already lives in Rust or cargo, wants agent sessions self-hosted, and prefers files over a proprietary store.
Models under the hood
as of 2026-11-06
Limitations
- It is a set of separate open-source projects — Cydonia, Bezel, CrabLLM and the CrabTalk daemon — installed via a curl shell script or Cargo rather than a click-to-start app; the former desktop Studio app has been retired and its pages are preserved only as an archive.
- The Cydonia workspace runs on ACP-compatible coding agents you install and pay for yourself (the Hobby plan), while model access is only included on the $8/month Go plan.

Skip it if Skip Crabtalk if you want a single integrated app — this is four separate open-source projects (Cydonia, Bezel, CrabLLM, the daemon) you install and wire together yourself.
GeneratedReal-world workflow fit
Concrete scenarios for the personas Crabtalk actually fits — and what changes day-one when you adopt it.
Install the daemon with the one-line curl script, run `crabtalk --version` to confirm, then open a project directory in Cydonia and point an agent at Anthropic through CrabLLM so all routing goes through one endpoint.
Outcome: Agent sessions run continuously, output lands as plain files in the directory you opened, and provider failover is handled by CrabLLM rather than app code.
Deploy CrabLLM as the single gateway binary in front of OpenAI, Anthropic and Ollama, and move each service's client to the one endpoint instead of three provider SDKs.
Outcome: One place to manage routing, failover and budget, and swapping a provider becomes a gateway config change instead of an app redeploy.
Add `bezel = "0.1"` to Cargo.toml, build the interface against its SwiftUI-inspired GPUI API and apply a shared theme.
Outcome: Native widgets and consistent styling without writing the component layer from scratch.
Use cases
- Drive ACP-compatible coding agents from a desktop workspace while keeping every file on your own disk.
- Put one gateway binary in front of OpenAI, Anthropic and Ollama with routing, failover and budget handling.
- Run an always-on daemon that manages several independent agent sessions and streams events to a client.
- Build a native Rust interface with a prebuilt GPUI component library and shared theming instead of writing widgets.
- Author reusable skills as Markdown files with YAML frontmatter that every agent on the install can pick up.
Setup time & first value
How long it actually takes to get something useful out of Crabtalk — broken out by persona, not the marketing-page minute.
One-line curl install on macOS, Linux or Windows gets the binary down in minutes; `cargo install crabtalk` works if you already have Rust. Windows users need a MINGW, MSYS2 or Git Bash shell, and the binary lands in %LOCALAPPDATA%\crabtalk\bin. Wiring CrabLLM in front of your providers and defining your first Markdown skill is the real first-value step, so budget an afternoon rather than five
Switching to or from Crabtalk
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a hosted agent runtime: move session output to a directory you open in Cydonia so files stay on your disk instead of a vendor store.
- →From three provider SDKs in app code: point clients at one CrabLLM endpoint and let the gateway handle routing and failover.
- →From a hand-rolled Ollama wrapper: replace it with CrabLLM and keep OpenAI and Anthropic one config entry away.
- ↗To a managed agent platform: your Cydonia output is already plain files on disk, so it moves without an export step.
- ↗To a packaged LLM gateway: CrabLLM config is provider endpoints and routing rules, so it ports to another gateway with matching settings.
