What’s new in Foglamp.

​

June 19, 2026

New features

npx foglamp login CLI. Authenticate from your terminal with the new device-authorization flow: run npx foglamp login, approve the code in your browser, and Foglamp mints an API key and writes FOGLAMP_API_KEY to your .env. Zero runtime dependencies — Node 18+ built-ins only — so it drops cleanly into agent-driven setups. See the Quickstart.

Animated API key reveal. Newly created API keys now roll from the name you gave them into the real value on reveal, so it’s obvious which key just appeared. The keys table also has pinned column widths and shows Last used before Created. See Projects, keys & billing.

Updates

Dark-mode polish across the dashboard. Refined shadows, borders, and hover states on cards, dialogs, and tables for better contrast and less visual noise in dark mode.

Bug fixes

• Foggy’s hidden composer now blurs when the panel closes, so keystrokes stop landing in it and the F shortcut reopens the panel reliably.
• Product analytics no longer load in local and preview environments.

New features

Model vs. tool latency split. LLM steps now record the pure provider-call time (modelCallMs) separately from client-side tool execution. The span still covers the whole step — the waterfall adds a sky model segment (tool time is the remainder), and the span inspector shows the split. Captured on AI SDK v7; v4–v6 (wrap) and non-reasoning paths simply omit it — no estimates.

Grounding sources. RAG/grounding citations a model reports (StepResult.sources) are captured per step and listed in the span inspector. Recorded only when output capture is on.

Model-drift fingerprint & safety ratings. The OpenAI-style system_fingerprint is captured as a queryable column (spot a silent weight change across otherwise-identical calls), alongside provider safety ratings. No logprobs are captured.

Rate-limit headroom. Provider rate-limit response headers (OpenAI x-ratelimit-*, Anthropic anthropic-ratelimit-*) are normalized into a cross-provider set — requests/tokens remaining, limit, and time-to-reset — so “you’re at 90% of your TPM” becomes queryable. Only rate-limit headers are read; no other headers are stored.

The provider signals above (sources, fingerprint, safety, rate-limit) are captured for text and object generation alike — generateText, streamText, generateObject, streamObject — and flow through the ToolLoopAgent/Experimental_Agent wrappers too. The model-vs-tool latency split is the one exception: it needs the AI SDK v7 model-call lifecycle, so it lands on v7 text/agent steps and is absent on the object path (which calls the provider directly, with no separable model window) and on v4–v6 — never estimated.

Self-hosters: deploy ingest before upgrading the SDK, since older ingest rejects the new span fields.

New features

Reasoning (extended thinking) capture. Both SDK collectors now record reasoning stream chunks: per-step thinking duration plus an intra-stream reasoning-token curve, sampled exactly like text chunks. The trace waterfall shows a violet thinking segment on reasoning steps, and the span inspector’s TTFT splits into thinking time + time to first visible text. Models that don’t reason (or SDK majors that don’t report reasoning tokens) send nothing — no estimates. Self-hosters: deploy ingest before upgrading the SDK, since older ingest rejects the new span fields.

Agent cost breakdown donut. The agent page now shows where an agent’s spend goes — prompt, completion, reasoning, cache read/write, requests, images, and web search — summed per pricing dimension over the selected range. See Agents.

Ambient trace context with fog.run(). Wrap any call with fog.run(context, fn) and every traced call inside picks up the workflow, session, and metadata automatically — no parameter threading, singletons stay singletons. See the SDK overview.

Typed with() context binding and agent-class wrapping. fog.with(ctx) now returns wrapped functions typed exactly like the originals, and foglamp/wrap ships drop-in wrappers for ToolLoopAgent and Experimental_Agent with per-call tool attribution. See AI SDK v4–v6 (wrap).

Forgot-password and account recovery. A new password-reset flow, plus a redesigned accept-invitation page with explicit accept/decline and a wrong-account recovery path.

Shareable list views. Search, filter, sort, and pagination on Traces, Sessions, Agents, and Workflows are now reflected in the URL — copy the link and a teammate lands on the same view.

Profile picture in the sidebar. Google sign-in users now see their photo in the sidebar; email/password users keep the initials avatar.

Updates

Confirmation dialogs for destructive actions. Deleting a project, provider key, pricing override, invitation, or access grant now prompts before it commits — project deletes require type-to-confirm.

Louder SDK auth failures. The transport now warns once on a 401 or 403 from ingest, even without debug mode, so a bad API key can’t silently drop every trace.

Vercel waitUntil without the peer dependency. The SDK reads the Vercel runtime context directly, so serverless flushing works without adding @vercel/functions to your project.

Eval scores on a 0–1 scale. Numeric judges now score on a normalized 0.00–1.00 scale (was 1–5), with an Avg score stat card on the Evals page that reflects active filters.

Deleted active project no longer strands the app. Deleting the currently selected project now falls back to another project instead of leaving the dashboard blank.

Newly created projects stay selected. Creating a project now keeps it as the active project instead of reverting to the first one in the list.

Onboarding key stability. The onboarding panel no longer revokes prior keys you may have already pasted into your code — the minted key is cached and reused while valid.

Bug fixes

• Bedrock model IDs and dash-versioned Anthropic IDs (e.g. claude-haiku-4-5) now resolve to pricing instead of recording null cost.
• Hardened model-ID normalization for -fast Anthropic variants, 3.x IDs, and additional Bedrock creators (OpenAI, Qwen, Luma, Stability, TwelveLabs, DeepSeek R1).
• Fixed a 500 in the usage-by-day query caused by a column alias collision.
• Trace inspector card shadow is now visible in light mode.
• Brightened the default button hover state in dark mode.
• Invitation flow now survives sign-in: unauthenticated users bounce through login and return to the invitation, and zero-org dashboards list pending invitations with an Accept button.
• Disabled form controls while mutations are pending to prevent duplicate submissions.
• Removed loading flashes on the billing plan and encryption banner.
• Stale project-scoped detail routes now redirect on project switch.
• Escape closes the Foggy panel.

New features

Sessions view. Follow a single conversation or user thread end to end. Set a sessionId on your calls and Foglamp groups every turn — across workflows and agents — under one session. See Sessions.

AI SDK v4–v6 support via foglamp/wrap. A new wrap adapter instruments older AI SDK versions without requiring an upgrade to v7. Drop-in replacement for generateText, streamText, generateObject, and streamObject — same traces, same ingest endpoint. See AI SDK v4–v6 (wrap).

Web-search usage in traces. Provider-reported web-search calls are now captured alongside token usage and cost, so search-heavy agents are billed and analyzed accurately.

Compile-time workflow safety. The SDK now enforces that workflowName and workflowRunId are passed together at the type level — invalid combinations fail at build time rather than producing orphaned spans.

Better dashboard navigation. Breadcrumb back-nav, card/table view toggles, and column filtering + sorting are available across list pages — including Traces, Workflows, and Agents.

Editable project name & URL. Change a project’s name and URL from Org settings → General without recreating it — the URL drives the favicon shown in the project switcher. See Projects, keys & billing.

Eval judge model picker. Choosing a judge model when creating an eval now uses an icon dropdown so providers and models are easier to identify at a glance.

Copy-paste instrumentation in empty states. Empty Agents and Workflows pages now show ready-to-run snippets so new projects can ship their first trace without leaving the dashboard.

Updates

Syntax-highlighted code blocks. Code blocks across the dashboard are now rendered with Shiki and follow the app theme — github-light in light mode and vesper in dark mode.

Bug fixes

• Hardened the ingest path against oversized span metadata and capped onboarding-key accumulation.
• Resolved access-control and denial-of-service issues surfaced in a security review.
• Fixed the onboarding telemetry API so first-trace detection fires reliably.
