7 Python Libraries That Replaced My Paid Subscriptions

I used to pay for 7 different SaaS tools. Then I discovered that Python libraries do the same thing for free.

Here's every subscription I cancelled and what replaced it.

1. Pandas → Replaced Excel ($14/mo)

I was paying for Microsoft 365 mainly for Excel. Pandas does everything Excel does, but programmable.

import pandas as pd

# Read any format
df = pd.read_csv("sales.csv")  # or .xlsx, .json, .sql, .html

# Pivot tables
pivot = df.pivot_table(values="revenue", index="month", columns="product", aggfunc="sum")

# VLOOKUP equivalent
merged = pd.merge(orders, customers, on="customer_id")

2. BeautifulSoup + Requests → Replaced ScrapingBee ($49/mo)

import requests
from bs4 import BeautifulSoup

resp = requests.get("https://example.com")
soup = BeautifulSoup(resp.text, "html.parser")
prices = [el.text for el in soup.select(".price")]
Enter fullscreen mode Exit fullscreen mode

For 90% of scraping tasks, you don't need a paid service.

3. Matplotlib + Seaborn → Replaced Tableau ($75/mo)

import matplotlib.pyplot as plt
import seaborn as sns

sns.set_theme()
fig, axes = plt.subplots(1, 2, figsize=(12, 5))
sns.lineplot(data=df, x="date", y="revenue", ax=axes[0])
sns.barplot(data=df, x="product", y="sales", ax=axes[1])
plt.savefig("dashboard.png", dpi=150)
Enter fullscreen mode Exit fullscreen mode

Saved: $900/year

4. Scikit-learn → Replaced DataRobot ($400/mo)

from sklearn.ensemble import RandomForestClassifier
from sklearn.model_selection import train_test_split

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)
model = RandomForestClassifier(n_estimators=100)
model.fit(X_train, y_train)
print(f"Accuracy: {model.score(X_test, y_test):.2%}")
Enter fullscreen mode Exit fullscreen mode

Saved: $4,800/year

5. Schedule + APScheduler → Replaced Zapier ($20/mo)

import schedule
import time

def check_prices():
    # Your automation logic here
    pass

schedule.every(1).hour.do(check_prices)
schedule.every().monday.at("09:00").do(send_report)

while True:
    schedule.run_pending()
    time.sleep(60)
Enter fullscreen mode Exit fullscreen mode

Saved: $240/year

6. NLTK + spaCy → Replaced MonkeyLearn ($200/mo)

import spacy

nlp = spacy.load("en_core_web_sm")
doc = nlp("Apple is looking at buying U.K. startup for $1 billion")

for ent in doc.ents:
    print(f"{ent.text}{ent.label_}")
# Apple → ORG | U.K. → GPE | $1 billion → MONEY
Enter fullscreen mode Exit fullscreen mode

Saved: $2,400/year

7. SEC EDGAR API → Replaced Yahoo Finance Premium ($50/mo)

import requests

headers = {"User-Agent": "MyApp (email@example.com)"}
url = "https://data.sec.gov/api/xbrl/companyfacts/CIK0001318605.json"
data = requests.get(url, headers=headers).json()
Enter fullscreen mode Exit fullscreen mode

Saved: $600/year

Total Savings: $9,696/year

Paid Tool Cost Python Replacement Cost
Excel (M365) $168/yr Pandas $0
ScrapingBee $588/yr BeautifulSoup $0
Tableau $900/yr Matplotlib + Seaborn $0
DataRobot $4,800/yr Scikit-learn $0
Zapier $240/yr Schedule $0
MonkeyLearn $2,400/yr spaCy + NLTK $0
Yahoo Finance $600/yr SEC EDGAR API $0
Total $9,696/yr $0

Obviously there's a time investment to learn these libraries. But once you do, you never go back.

What paid tool have you replaced with a free alternative?

I'm always looking for more swaps.
