Claudoscope is a free, open-source macOS menu bar app that gives Claude Code users a full session history browser, cost analytics, and search across all their coding sessions. It reads directly from local JSONL session files in ~/.claude/projects/ and works entirely offline — no telemetry, no data sent anywhere, fully MIT-licensed. The tool estimates costs from raw token counts against published API pricing, giving developers a clear picture of where their Claude Code spend is going across projects and sessions. It also automatically scans for leaked API keys and credentials in session content — effectively adding a passive security audit to every session review. Claudoscope fills a real gap: Claude Code's built-in /cost command only covers the current session. Claudoscope gives historical visibility and project-level analytics. It works with any Claude Code deployment including Enterprise API setups where cookie-based session trackers fail. Built and maintained by an indie developer, free forever.

Coasts
Containerized sandboxes for running AI agents safely in production

Coasts (Containerized Hosts for Agents) is an open-source infrastructure layer that solves one of the practical problems of running AI agents in production: safe, isolated execution environments. When an agent needs to browse the web, execute code, access files, or call external APIs, it needs a sandbox that prevents it from accidentally (or intentionally) doing damage to the host system or other agents. Coasts provides a lightweight, Docker-based hosting layer with per-agent isolation and configurable capability grants. The core abstraction is the "coast" — a container configuration that specifies exactly what an agent can and cannot access: which file paths are readable or writable, which network endpoints can be called, what CPU/memory limits apply, and how long the agent can run. Agents are spun up in these containers on demand and torn down after completion, providing strong isolation with minimal overhead. The configuration is declarative (YAML-based) and composable, making it easy to define agent capability profiles. With 98 points on Hacker News and 39 comments — one of the higher engagement rates in the agent infrastructure space — Coasts is hitting a real need. As more teams build agent pipelines in production, the question of "what happens when the agent does something unexpected" becomes critical. Container-based isolation is the proven answer from the broader DevOps world, and Coasts applies it specifically to the agentic AI context.
Reviewer scorecard
“As someone who runs Claude Code 8+ hours a day, this is immediately valuable. I had no idea which projects were burning through tokens until I installed it. The leaked credential detection is a bonus I didn't expect — it already caught a test API key I'd forgotten to rotate.”
“The declarative capability grants are exactly what I want — specify what an agent can touch and nothing more, spun up in a container with resource limits. This is the infrastructure pattern for production-safe agent deployment. YAML-based config means it slots naturally into existing IaC workflows.”
“This is fundamentally a log file reader with cost estimation math. Anthropic could ship this natively in Claude Code in a single PR and make Claudoscope obsolete overnight. The gap it fills is real, but the risk of deprecation-by-inclusion is very high for an indie-maintained tool.”
“Container isolation is standard infrastructure work, and there are already several competing approaches (E2B, Modal, Daytona) with more polish and enterprise backing. Starting a new OSS project in this space faces real network effects headwinds. The real question is what Coasts offers that existing solutions don't.”
“The emergence of cost-tracking tools for AI coding sessions is a leading indicator of developer maturity. When developers start optimizing their AI spend like they optimize their AWS bill, we've crossed a real threshold. Claudoscope is primitive, but it's the first version of what becomes a full AI development economics dashboard.”
“The agent execution environment is going to become as important as the agent itself. As AI agents take real actions in the world — browsing, coding, executing — the infrastructure for capability isolation determines what's safe to automate. Coasts' open-source approach is important for avoiding vendor lock-in in this critical layer.”
“Indie developers and freelancers who need to track Claude Code costs against client projects will love this. The project-level breakdown finally makes AI tool costs legible as a line item on a client invoice — something that's been surprisingly hard to do until now.”
“Deep DevOps infrastructure work — not relevant to creative workflows unless you're running a production AI system. The people who need this will know they need it; everyone else should wait for higher-level abstractions that hide the container complexity.”
