Zero-config 1-click launch
Launch debugging directly from breadcrumbs and file actions without hand-authoring launch configuration JSON files or memorizing CLI flags.
AI debugger & profiler
AI Debugger & Profiler: 1-Click breakpoints, flamegraphs, and AI triage.
Debug and profile code with zero manual launch configuration. Set breakpoints, inspect scoped variables, capture CPU flamegraphs, and let AI agents diagnose bugs and optimize performance.
The problem
Setting up debuggers and external profilers wastes hours before you even hit a breakpoint.
Traditional IDE debugging requires wrestling with complex JSON launch files, mismatched sourcemap configurations, runtime flags, and terminal attach scripts. When things get difficult, developers often fall back to scattering print statements across their codebase.
When performance problems arise, you have to switch to external profiling suites, export cumbersome trace dumps, and guess which function is causing latency spikes.
Flame unifies interactive debugging, CPU flamegraph profiling, and AI agent intelligence into one streamlined workflow. Click Debug Script to start stepping immediately, inspect live variables inline, and let AI agents explain stack traces and optimize hot code paths.

How Flame solves it
From code issue to verified performance fix in five steps.
- 01
One-click debug launch
Click Debug Script directly from editor breadcrumbs or file actions to attach immediately without writing complex launch configuration files.
- 02
Set gutter breakpoints & logpoints
Click the editor gutter to toggle line breakpoints, configure conditional pause expressions, or insert logpoints that print values without stopping execution.
- 03
Inspect variables & inline values
Pause execution to inspect Local, Closure, and Global scopes, monitor dynamic watches in real time, and view live evaluated values inline in Monaco.
- 04
Step & navigate call stacks
Step Over, Step Into, and Step Out with intuitive shortcuts. Click across stack frames to navigate call stacks and trace asynchronous boundaries across files.
- 05
Record CPU profiles & optimize with AI
Capture CPU execution profiles, explore zoomable canvas flamegraphs, and hand execution hotspots directly to AI agents to refactor performance bottlenecks.
Debugging & profiling features
Everything you need to diagnose bugs and optimize execution speed.
Gutter breakpoints & logpoints
Set standard line breakpoints, conditional pause expressions, and non-breaking logpoints directly in the editor gutter.
Scoped variable inspection
Expand Local, Closure, and Global scopes, add dynamic watch expressions, and evaluate arbitrary statements in the debug REPL console.
Monaco inline execution values
See live variable values and execution states rendered directly beside your source lines while stepping through code.
Interactive CPU flamegraphs
Capture CPU profile traces with an interactive zoomable canvas flamegraph and a Top Functions table highlighting self and total execution time.
AI root-cause diagnosis & triage
Send paused execution frames, stack traces, and flamegraph hotspots directly to AI agents to pinpoint bugs and refactor slow algorithms.
