What is Time Travel Debugging?
Time Travel Debugging (TTD) records the complete execution of a system into a deterministic trace. Unlike a traditional debugger, which observes a live execution and mostly moves forward, TTD lets you navigate backward and forward through everything that happened.
With Epoch, the AI agent or the security analyst can explore what actually happened: follow data, inspect state, trace control flow, move across processes and revisit any point in the execution as often as needed.
The trace becomes the investigation ground truth that feeds the agent with the right context for deep security analysis.

Capture the entire system execution
Capture the full execution in one pass, with intermediate states preserved as snapshots. Every instruction, memory change, and register state lands in a persistent trace file.
Navigate the timeline forward or backward
Move forward or backward, or jump straight to a specific instruction. The state is frozen, so even race conditions and kernel panics are fully reproducible.
Tag, search, and inspect the trace
Tag events on the timeline, pull up symbols, and search the trace for specific strings. Memory state is available at every instruction.

Query your trace with local Agentic AI
Connect your LLM via Epoch's dedicated MCP server. Because the dynamic chaos is now a structured, static dataset, the AI can explore millions of instructions, flag vulnerability patterns, and surface the root cause directly, then tag the trace and hand you back to Epoch Analysis to get evidence.

Frequently Asked Questions
They serve different purposes. Epoch is built for full-system visibility, Windows, Linux, Android, IoT, with an unfiltered view of the kernel and all active processes at once, for deep reverse engineering and threat analysis.
LLMs need deep context, which traditional debuggers can't provide. Epoch turns execution into a static, searchable dataset, so an AI agent can navigate millions of instructions via our MCP server, finding root causes manual stepping would miss.
Yes. Epoch doesn't replace disassemblers or debuggers, it complements them. They help you understand the code, Epoch helps you understand the execution.
Standard dynamic analysis only moves forward. Because TTD records the entire system state deterministically, exploring the trace is like scrubbing through a video, you can step backward from a crash as easily as forward.
