It includes a model cost calculator (batch and flex discounts, fast and ultrafast multipliers, cache reads and writes, per-request long-context tiers), a usage audit that recalculates spend from your own OpenAI or Anthropic usage export and reconciles it against your cost records to within one cent, and model-switch modelling with a CSV migration plan.

FluxyChat
Web · 1 recommendations
FluxyChat
FluxyChat puts people and AI agents in the same realtime room. Most products end up with chat in one place, the document in another and the agent somewhere else, with permissions copied between them and no way to replay what a tool call did. FluxyChat keeps chat, presence, collaborative docs and agents on one Cloudflare Durable Object per room, so agent tool calls show up on the same timeline as messages, and risky ones can wait for a human to approve. It’s open source (MIT): self-host it on your own Cloudflare account or use the hosted open beta (free plan, no card). I started it in May as a weekend project and kept building it solo. You can try a public room without signing up at fluxychat.com/demo.
