21
+# 🔌 Free Online SPICE Simulators
22
+
23
+## 1. Falstad Circuit Simulator
24
+- [https://falstad.com/circuit](https://falstad.com/circuit)
25
+- Browser-based, very visual, easy for beginners.
26
+- Drag-and-drop schematic style.
27
+- Not strict SPICE syntax, but good for quick logic/analog tests.
28
+- Limited component models (no full LM358), but can approximate op-amps.
29
+
30
+---
31
+
32
+## 2. Ngspice on EasyEDA
33
+- [https://easyeda.com](https://easyeda.com) (free signup required)
34
+- Cloud schematic editor with SPICE simulation built-in.
35
+- Supports real models (LM358, MOSFETs, etc.).
36
+- Can go directly from schematic → PCB.
37
+- Good if you want both sim + PCB design in one.
38
+
39
+---
40
+
41
+## 3. PSPICE Online (OrCAD Cloud)
42
+- [https://pspice.com/simulation](https://pspice.com/simulation)
43
+- Web-based version of OrCAD PSpice.
44
+- Requires free registration.
45
+- Professional-grade, supports vendor models.
46
+
47
+---
48
+
49
+## 4. CircuitLab
50
+- [https://www.circuitlab.com](https://www.circuitlab.com)
51
+- In-browser schematic capture + simulator.
52
+- Clean interface, works like LTspice lite.
53
+- Free version has limitations (saving/exporting), but works for small circuits.
54
+
55
+---
56
+
57
+## 5. TINACloud (Texas Instruments)
58
+- Desktop: [https://www.ti.com/tool/TINA-TI](https://www.ti.com/tool/TINA-TI)
59
+- Online: [https://www.tina.com/tinacloud/](https://www.tina.com/tinacloud/)
60
+- TI’s free simulator, works with TI models (LM358 included).
61
+- Requires TI account.
62
+
63
+---
64
+
65
+## 6. PartSim
66
+- [https://www.partsim.com](https://www.partsim.com)
67
+- Browser-based, SPICE backend.
68
+- Free and simple, good for hobby-level circuits.
69
+- Not as advanced as LTspice, but decent for quick tests.
70
+
71
+---
72
+
73
+# ⚡ Recommendation
74
+- **Beginner / quick tests** → Falstad.
75
+- **Want real LM358 model + PCB** → EasyEDA.
76
+- **More professional, TI chips** → TINACloud.
77
+- **General purpose** → CircuitLab or PartSim.
