What's New in v1.1.0
- 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
/fastat 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.

About
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.

Features
Analytics dashboard
| Accurate cost math | Per session · day · model. Published pricing for every Claude — Opus 4.8 (with fast mode), 4.7, 4.6, 4.5, 4.1, 4, 3; Sonnet 4.6, 4.5, 4; Haiku 4.5, 3.5, 3. Speed-aware per-turn, so fast turns price at 2×. Compare like-for-like whatever plan you're on. |
| A – F cache health grade | Trend-weighted hit ratio — cchubber-style. See your direction, not just your current number. |
| Model routing insights | Opus / Sonnet / Haiku split + "you could save $X by rerouting N sessions to Sonnet" estimate. |
| Inflection detection | Any session ≥ 2 × baseline cost-per-session gets flagged with context. |
| Recommendations engine | Every finding has a Copy Fix Prompt button. Paste it into Claude Code. Problem fixed. |
| Plan usage limits | Current session · weekly all-models · Sonnet-only · Extra Usage monthly spend. Auto-detects Pro / Max / Teams. Sound alert on Extra Usage spikes. |
| Heatmap · sparklines · charts | All-local Chart.js. Zero network. |

Usage
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.
Roadmap
- Linux tray icon — system-tray quick toggles (Discord presence on/off, pause analytics, open dashboard) via Tauri's
tray-iconfeature. 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.
