Ferretlog is a zero-dependency pure Python CLI that treats your Claude Code session logs like a git repository. It parses the raw JSONL logs in `~/.claude/projects/` and gives you git-style history browsing, diff between runs, per-tool-call breakdowns, and cost/token stats — entirely locally, with no network calls and no configuration required. If you've been using Claude Code heavily, you've likely experienced the frustration of losing track of what changed across sessions, what tools were called how many times, and how much each session actually cost across sub-agent calls. Ferretlog makes that history explorable and comparable the same way `git log` makes code history explorable. This is an indie solo project from Eitan Lebras, submitted as a Show HN. It's genuinely useful as a power-user tool for anyone doing serious Claude Code work, especially those managing multi-session agent pipelines where debugging "what did the agent do last time?" is a real pain. The zero-dependency, local-only design means there's no trust surface and no setup friction.

Fixa is a cloud-native AI coding agent that goes beyond code completion to handle end-to-end project scaffolding, deployment, and iterative refinement — all without any local setup. Launched on Product Hunt today, it lets developers describe a project in plain language and returns a running, deployed application within minutes. Unlike Bolt, Replit, or Lovable — which run in browser-based sandboxes — Fixa provisions real cloud infrastructure (compute, database, CDN) on your behalf and maintains persistent agent state between sessions. You can leave a session and return to find the agent has continued iterating on your project based on usage data it collected from real traffic. The differentiator is the feedback loop: Fixa monitors the deployed app's error logs and user interactions and proactively proposes fixes or improvements without being asked. It supports Node.js, Python, and Go projects, connects to GitHub for version control, and integrates with Stripe, Supabase, and Cloudflare out of the box.
Reviewer scorecard
“If you run Claude Code daily, you need this immediately. Being able to diff two sessions like git commits and see exactly which tools fired and what they cost is something that should have existed from day one. Zero-dependency Python means it just works.”
“The persistent agent state between sessions is genuinely new — most AI coding tools forget everything when you close the tab. The automatic error monitoring and proactive fix proposals are early-stage but already useful for catching dumb mistakes in side projects.”
“This is a niche tool for a niche user (heavy Claude Code power users) and the session log format Anthropic uses is undocumented and could change at any update. Tying workflows to internal log parsing is fragile infrastructure — treat it as a convenience, not a dependency.”
“Letting an AI agent autonomously modify production code based on user behavior data is a significant trust leap. The free tier is one project, and cloud infrastructure costs aren't fully transparent at signup. Wait until the auto-deploy feature has more community vetting before pointing it at anything real.”
“Agent observability tooling built by the community, not the vendor, is how this ecosystem will mature. Ferretlog is primitive but it points at a real gap: we need git-style versioning and auditability for agent sessions, not just for code.”
“This is what 'AI-native software development' actually looks like — not just autocomplete, but an agent that's accountable for the running system. The feedback loop from production traffic to code changes is a glimpse at how most software will be maintained in five years.”
“Terminal-only, Claude Code-specific, no visuals — this tool exists entirely outside my workflow. The underlying insight (session replay and cost tracking) is useful, but it needs a UI before it reaches anyone outside the developer community.”
“For non-technical creators who want to ship a product without learning DevOps, Fixa removes the biggest friction points: hosting, databases, and deployment. I spun up a newsletter landing page with a waitlist in under 10 minutes.”
