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.

smolvm is a lightweight microVM runtime built in Rust on top of libkrun, designed specifically for sandboxing AI coding agents and untrusted code execution. VMs cold-start in under 200ms and ship as portable `.smolmachine` files — think Docker images but hardware-isolated. It supports macOS (Apple Silicon and Intel) and Linux, with opt-in networking so that untrusted code can't exfiltrate credentials or phone home by default. The project includes an explicit AGENTS.md to help coding agents understand how to use it, and was built with autonomous code execution in mind. When an AI agent needs to run user-submitted code or iterate on its own suggestions, smolvm gives it a proper hardware sandbox rather than a leaky container. Version v0.5.18 landed April 17, 2026. With AI coding agents increasingly running arbitrary code in tight loops, the security story around containerization has become critical. smolvm fills a real gap: fast enough to not break agentic workflows, isolated enough to actually protect the host machine and credentials. It surfaced on Hacker News with 259 points and strong technical discussion, suggesting genuine resonance with the developer community building agentic tools.
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.”
“This is the missing layer for anyone running AI agents that execute code. Docker containers have always been too porous for untrusted execution, and smolvm's sub-200ms coldstart means you can spin a fresh VM per agent turn without killing your latency budget. The AGENTS.md is a thoughtful touch — shows the authors actually understand the workflow.”
“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.”
“At v0.5.18 this is still early software and the docs are sparse. libkrun has its own surface area of bugs, and running microVMs at agent-loop speed on macOS introduces a whole class of Apple Hypervisor Framework edge cases. I'd wait for v1.0 and a production case study before betting real workloads on this.”
“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.”
“Every autonomous agent that executes code needs a proper sandbox — not a polite request for the agent to be careful. smolvm represents the infrastructure layer that makes truly autonomous code execution safe enough to deploy at scale. This kind of primitive is foundational for the agentic software era.”
“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.”
“For anyone building AI tools that touch code, smolvm means you can let your AI actually run things without fear. That unlocks a whole category of 'show me the output' UX patterns that weren't safe before. Less time explaining sandboxing to users, more time shipping features.”
