Open-source AI gateway and LLM observability: one API for 100+ models, cost and latency tracking, prompt management.
Best alternatives to Foglamp in 2026
The way a car's dashboard warns you something's wrong before the engine actually fails, Foglamp is meant to sit behind an AI agent and flag problems before they reach a user — without anyone having to manually read through logs. If you've built something on top of Claude or another LLM and have no real visibility into what it's actually doing, costing, or getting wrong once it's live, that's the gap this fills. Concretely, Foglamp monitors LLM calls to track cost, latency, and output quality over time, and is built specifically to plug into the Anthropic Claude Agent SDK and Claude Code — setup is a single prompt pasted into Claude Code that wires up the instrumentation automatically, rather than a manual SDK integration. It provides a dashboard for inspecting individual calls, configurable alerts, and evaluation runs (evals) to catch quality regressions. All plans include unlimited agents, workflows, and traces; what's actually rationed is data volume (spans) and how long that data is retained.

- ✓ One-line integration via proxy — instant cost/latency visibility
- ✓ Gateway + observability in one: routing, fallbacks, one key for 100+ models
Website monitoring built for non-technical site owners — plain-language alerts the moment your site goes down, your SSL certificate nears expiry, or your domain is about to lapse.
- ✓ Alertes claires, sans jargon
- ✓ Gratuit réellement exploitable
Turns a plain-language description of a critical user flow into an approved, schedulable browser check — no Playwright scripting required.
- ✓ Gratuit et open source, aucun abonnement
- ✓ Checks lisibles/versionnés dans le repo git
Watches your websites, APIs, and servers around the clock and pings you on Slack, Discord, email, or a webhook the moment something goes down or a disk is about to fail.
- ✓ Surveille aussi la santé matérielle des serveurs, pas juste l'uptime
- ✓ Vérification multi-localisation, alertes multi-canaux
A privacy-focused API monitoring tool that shows you request metrics, errors, and traces for your backend with a few lines of setup, across 23+ frameworks in Python, Node.js, Go, C# and Java.
- ✓ 23+ framework integrations across Python, Node.js, Go, C#, Java
- ✓ Privacy-by-default: minimal data collection, field masking controls
A platform that watches your team's AI coding agent sessions and PR reviews, then turns the useful patterns into reusable skills so the next session doesn't relearn the same thing.
- ✓ Extraction automatique de compétences réutilisables
- ✓ Handoff de session avec contexte complet
Turns your raw AI coding agent transcripts into a dashboard that shows exactly what each feature or PR actually cost, which tools kept failing, and where the agent kept redoing the same work.
- ✓ Attribution de coût précise par PR/fonctionnalité
- ✓ Détecte les schémas de re-travail répétitif
A free, open-source tool for watching over network infrastructure spread across remote or hard-to-reach sites — think branch offices, edge locations or restricted networks — where you can't just install a normal monitoring agent everywhere.
- ✓ Fully open source (Apache 2.0), free to self-host
- ✓ Purpose-built for remote, segmented or edge network monitoring
A free, open-source observability platform that unifies logs, metrics, traces, errors and session replays in one searchable interface — a self-hosted alternative to Datadog.
- ✓ Free and open-source, MIT license
- ✓ Unified logs/metrics/traces/replays UI out of the box
A grading and testing platform for voice AI agents — it listens to how your phone bot actually performs and scores it against rules you define, instead of you finding out it went off-script from an angry customer call.
- ✓ Multi-signal analysis (audio, conversation, tool execution)
- ✓ Version-pinned batch testing for regression detection
A local meter that tells you exactly how much your AI coding tools (Claude Code, Cursor, Copilot, and others) are actually costing you, reading their logs on your own machine instead of sending anything to a server.
- ✓ Local-first, zero telemetry — never uploads prompts or code
- ✓ Covers 8 different AI coding tools in one unified report
