• OpenAI Codex support — flip the provider toggle and Pulse reads Codex sessions too. Full GPT-5 family pricing including GPT-5.5 ($5 / $30 per Mtok), 400 K context, and reasoning-effort detection.
• Claude Opus 4.8 — pricing, 1M-context GA, and inflated-tokenizer detection.
• Fast mode, priced right on both sides — Claude Opus 4.8 Fast at 2×; Codex /fast at 2.5× (GPT-5.5) and 2× (GPT-5.4). Each fast turn is flagged with a ⚡ marker in Sessions and Discord presence.
• Per-session Context Window — a session selector, per-session token usage, and tiered compaction hints.
• Reports & Insights no longer hangs — analyzers run off the UI thread; one scan feeds every view.
• Redesigned HTML export — fully offline, on-brand dark theme, smooth charts, fast-vs-standard split.

You pay for Claude Code every month. Maybe $20 on Pro, $100 – $200 on Max, or a seat on Teams. And yet, if someone asked "which of your sessions burned the most context this week?" or "what percentage of your tokens are actually cache hits?" — you probably can't answer.

Pulse answers. It reads Claude Code's own JSONL transcripts (zero-config — just install and launch) and surfaces the things that actually move the needle on your plan:

• A – F cache-health letter grade — trend-weighted, so you see the direction your cache efficiency is heading, not just today's number.
• Opus-4.7-tokenizer aware — Opus 4.7's new tokenizer inflates tokens by up to 35 %; Pulse flags the inflation so you know when you're hitting limits faster than expected.
• 1 M context GA pricing — flat per-token rate across the full 1 M window for Opus 4.6 · Opus 4.7 · Sonnet 4.6 (per Anthropic's official pricing, effective 2026-03-13). Older betas (Sonnet 4 / 4.5, Opus 4 / 4.5) still get 2× input · 1.5× output · 2× cache at > 200 K. Pulse applies the correct math per-model so you compare sessions like-for-like. Plan-level Extra Usage on Pro / Max / Teams is tracked separately.
• Inflection alerts — any session that blows past 2 × your rolling baseline gets flagged with context and a suggested fix.
• Fix-with-Claude prompts — every recommendation has a Copy Fix Prompt button. Paste it into Claude Code. Problem fixed.
• Plan usage limits — live tracking of your current-session, weekly, Sonnet-only, and Extra Usage quotas. Sound alert when Extra Usage spikes.
• Discord Rich Presence — five-tier reasoning effort, live project / model / branch. Your flow state, on your profile.

Works with OpenAI Codex too. Flip the provider toggle and Pulse reads your Codex CLI sessions the same way — per-model pricing for the GPT-5 family including GPT-5.5 ($5 / $30 per Mtok), 400 K context tracking, and reasoning-effort detection. Fast mode (/fast) is priced correctly on both sides: Codex GPT-5.5 bills at 2.5× and GPT-5.4 at 2× the standard rate, and Claude Opus 4.8 Fast bills at 2× — each flagged with a ⚡ marker in Sessions and Discord presence.

Privacy & ownership

• 100 % local. Your session data never leaves your machine. No telemetry, no phone-home, no cloud.
• SQLite at ~/.claude/pulse-analytics.db — yours to inspect, export, back up, or delete.
• Apache-2.0 licensed with required attribution. Fork it, audit it, ship your own version — just keep the NOTICE file and credit the original author per the license.

First launch → install Pulse → launch → it auto-detects your ~/.claude/ folder → keep using Claude Code; sessions stream in live.

Discord Rich Presence → open the Discord tab → pick a preset (Minimal · Standard · Full) or customize fields → toggle on. Custom presence artwork in docs/discord-assets.md.

Reports → open the Reports tab → read your cache grade + recommendations → click Copy Fix Prompt on any item → paste into Claude Code → done. Export HTML / Markdown for your team.

• Linux tray icon — system-tray quick toggles (Discord presence on/off, pause analytics, open dashboard) via Tauri's tray-icon feature. Parity with the Windows tray.
• MCP server inventory — list every MCP server Claude Code has loaded for each session, with its tool count, per-tool invocation frequency, and an estimated token cost per tool call. Helps spot noisy MCPs silently inflating your context.
• Budget-threshold desktop notifications — native OS notification when you cross configurable thresholds (e.g. "80 % of weekly limit", "Extra Usage just passed $150 of your $200 cap"). Replaces eyeballing the dashboard.
• Custom Discord presence templates — save / share named field layouts beyond Minimal · Standard · Full. Export a preset as JSON; import one from a teammate.
• Session replay — step through a past session's prompts and tool-call timeline with the same filters the live dashboard uses. Currently the data is there (JSONL traces) but there's no dedicated UI.
• Smarter cost forecast — weekly-reset-aware projections with a confidence band, instead of today's linear daily-average multiplication.
