C code → Flowchart • Instant visualization

Understand unfamiliar C code in minutes, not hours.

mAutoFlow automatically converts C source code into readable flowcharts so you can debug, review, and onboard faster—without manual diagramming.

Tip: Login is required to generate flowcharts. It takes a few seconds.

// Example
int compute(int x) {
  int sum = 0;

  if (x <= 0) return 0;

  for (int i = 0; i < x; i++) {
    if (i % 2 == 0) sum += i;
    else sum -= 1;
  }

  return sum;
}

Stop guessing what legacy C code does

When documentation is missing, understanding logic becomes the bottleneck. A clear flowchart reduces cognitive load and helps teams move faster.

Onboarding

New engineer? Existing project? Visualize flow and ramp up quickly.

Debugging

See conditions and loops at a glance, without reading line-by-line.

Reviews

Understand intent faster, spot risky paths, and communicate clearly.

How it works

Simple workflow. No diagram tools. No manual drawing.

3-minute intro
Step 1

Paste your C code

Drop a function or file snippet into the editor.

Step 2

Automatic analysis

mAutoFlow parses control-flow (if/else/loops/returns).

Step 3

Instant flowchart

Get a readable flowchart you can export or share.

From C code → Flowchart in seconds

Show a real, slightly complex example (with if/else + loop). This section is where users decide “OK, this is useful.”

Input
void motor_control(int mode, int rpm) {
  if (mode == 0) {
    stop();
    return;
  }

  init();

  while (rpm > 0) {
    step();
    rpm -= 10;
    if (rpm < 50) break;
  }

  finalize();
}
Output
Flowchart generated from the example C code

Built for engineers who deal with real-world C

mAutoFlow is most valuable when you inherit code, maintain legacy projects, or need to understand logic quickly.

Embedded & firmware engineers

Visualize control flow and reduce time spent reading unfamiliar code.

Legacy maintainers

Make sense of complex branching and loops without manual diagrams.

New team members

Onboard faster with clearer understanding of the code’s intent.

Your code stays safe

Trust is a conversion feature. State your policy clearly and early.

Processing

  • Code is processed only to generate flowcharts.
  • No training on your source code.
  • Login is required to generate flowcharts to prevent abuse.
  • HTTPS communication.

Storage (recommended wording)

  • Code is not stored by default.
  • Only stored if you explicitly save/share/export.
  • You can delete saved items anytime (if supported).
