Replace the hand-rolled table with a TanStack Table-backed shadcn
data-table using the FlexRender/createSvelteTable helpers, with
DropdownMenu column visibility, Select page-size, and icon-button
pagination. Column visibility and page size persist to localStorage.
Move tooltip usage to the canonical shadcn-svelte pattern by adding a
single root Tooltip.Provider in App.svelte and using Tooltip.Root/
Trigger/Content directly in the activity-table sub-components
(HeaderLabel, MetaCell), dropping the custom Tooltip/MetadataTooltip
wrappers.
- add @tanstack/table-core and shadcn data-table helpers
- split cell/header renderers into activity-table/* sub-components
- switch pagination/visibility to TanStack Table state driven by
table.nextPage/previousPage/setPageIndex/setPageSize and
column.toggleVisibility
Convert the remaining .btn usages (Concurrency, Performance, CaptureDialog)
to shadcn Button, fix CaptureDialog/PerformanceChart styles to shadcn
tokens, and remove the transitional legacy palette aliases and component
classes from index.css. Drop the now-unused lucide-svelte and shadcn-svelte
dependencies.

Set up shadcn-svelte components and adopt its design-token system as the
base for modernizing the UI. Switch dark mode from the data-theme attribute
to the .dark class so shadcn primitives theme correctly.
- add components.json, $lib alias (tsconfig + vite), cn() util
- install shadcn primitives under src/lib/components/ui
- rewrite index.css with shadcn tokens (zinc + brand teal accent)
- keep legacy utility/class aliases as a transitional shim
- toggle .dark class from theme store in App.svelte

Add a comprehensive performance monitoring system that collects CPU, memory, swap, load average, network IO, and GPU stats. Provides both a REST API for the UI and a Prometheus /metrics endpoint.
Backend changes:
- New internal/perf package with configurable interval-based stats collection
- GPU monitoring via LACT (Unix socket) and nvidia-smi fallback on Linux
- Ring buffer (internal/ring) for time-series stat storage
- Prometheus /metrics endpoint with all system and GPU metrics
- Moved LogMonitor to internal/logmon package
- New PerformanceConfig for hot-reloadable monitoring settings
- REST /api/performance endpoint replacing SSE streaming
UI changes:
- New Performance page with real-time charts for CPU, memory, GPU, and network
- Reusable PerformanceChart component
- LLAMA_SWAP_URL environment variable support
- Improved capture dialog display
Other:
- Example Grafana dashboard for Prometheus metrics
- monitor-test standalone binary
- Config schema and example updates
fixes#596
- inference handles to store an activity record for all inference endpoints
- add path, status code, and content type to Activities page
- toggle on/off columns no Activities page
- add configurable capture level for inference endpoints so large binary blobs are not stored in memory
- store captures in compressed binary format
Upgrade vite and related dependencies to take advantage of Vite 8's
improved build times via Rolldown and Oxc.
- vite: ^6.3.5 → ^8.0.0
- @sveltejs/vite-plugin-svelte: ^5.0.3 → ^7.0.0
- svelte: ^5.19.0 → ^5.46.4
- vite-plugin-compression2: ^2.4.0 → ^2.5.1
- vitest: ^4.0.18 → ^4.1.0

Add a copy-to-clipboard button that appears on hover for each code block
rendered in the chat interface assistant messages.
- Svelte action `codeBlockCopy` injects a button into every `<pre>`
element
- MutationObserver reattaches buttons as streaming content arrives
- Button shows a check icon for 2 seconds after a successful copy
- Uses clipboard API with execCommand fallback for non-secure contexts
- CSS hides button by default and reveals it on pre:hover

Add saving request and response headers and bodies that go through
llama-swap in memory.
- captureBuffer added to configuration. Captures are enabled by default.
- 5MB of memory is allocated for req/response captures in a ring buffer.
Setting captureBuffer to 0 will disable captures.
- UI elements to view captured data added to Activity page. Includes
some
QOL features like json formatting and recombining SSE chat streams
- capture saving is done at the byte level and has minimal impact on
llama-swap performance
Fixes#464
Ref #503
Reorganizes control placement in the playground interfaces and
improves form interactions for better UX, particularly on mobile
devices.
## Key Changes
- **AudioInterface & ImageInterface**: Moved "Clear" buttons from the
top control bar into the action button group below the form inputs for
better visual hierarchy and logical grouping
- **ImageInterface**:
- Added prompt clearing to the `clearImage()` function so the input
field is reset when clearing generated images
- Updated Clear button disabled state to also check if prompt is empty,
allowing users to clear an empty prompt
- Added responsive flex styling (`flex-1 md:flex-none`) to the Clear
button for better mobile layout
- **ExpandableTextarea**:
- Imported `untrack` from Svelte to properly handle reactive
dependencies
- Wrapped `expandedValue.length` in `untrack()` to prevent unnecessary
reactivity when setting cursor position
- Improved button visibility on mobile by changing opacity from
`opacity-0` to `opacity-60` with `md:opacity-0` breakpoint, making the
expand button more discoverable on touch devices
## Implementation Details
The `untrack()` usage in ExpandableTextarea ensures that reading the
text length doesn't create a reactive dependency, preventing potential
infinite loops while still allowing the effect to run when `isExpanded`
changes.
Replace the legacy React UI with the new Svelte-based one. Introduce a Playground in the UI to quickly test out text, image, text to speech and speech to text models behind llama-swap.
Key Changes
New Svelte UI (ui-svelte/)
- Multi-tab Playground with Chat, Image Generation, Audio Transcription, and Speech interfaces
- Chat: message editing/regeneration, markdown rendering with LaTeX math support, image attachments, code syntax highlighting
- Image: size selector, download/fullscreen viewing
- Audio: transcription with peer support
- Speech: voice caching with manual refresh, download button
- Responsive mobile layout with collapsible navigation
- XSS fixes and accessibility improvements
Proxy Improvements
- Add gzip/brotli compression for UI static assets (proxy/ui_compress.go)
- Add GET /v1/audio/voices?model={model} endpoint for voice listing
- Add peer support for /v1/audio/transcriptions
Trying out svelte for the UI. The port was done by Claude Code on the iOS app w/ Opus 4.5.
