OSS Alternatives Finder

Given any paid SaaS tool or commercial API, find and rank the best actively maintained open source alternatives by searching GitHub and developer communities in real time — then verify the health of each one and summarise exactly what a developer gains and loses by switching.

Pre-flight check

Before doing anything, verify TinyFish is installed and authenticated:

tinyfish --version
tinyfish auth status

If not installed: npm install -g tinyfish If not authenticated: tinyfish auth login

Step 1 — Understand the tool

Before searching, identify:

• Tool name — exactly as it is known (e.g. "Datadog", "Auth0", "Algolia")
• Primary use case — what problem it solves (e.g. "APM and log aggregation", "authentication", "search-as-a-service")
• Key features the user cares about — if not stated, infer from the tool's known capabilities

If the user hasn't told you what aspects matter most to them, ask one quick question: "Any features that are must-haves for your switch?" — then proceed.

Step 2 — Parallel discovery

Run all three discovery agents simultaneously using background processes. Each agent searches a different surface.

# Agent 1 — GitHub search for alternatives
tinyfish agent run \
  --url "https://github.com/search?q=open+source+alternative+{TOOL_NAME}&type=repositories&s=stars&o=desc" \
  "You are on a GitHub search results page for open source alternatives to {TOOL_NAME}.
   List the top 6 repository results. For each one extract:
   - full repo name (owner/repo)
   - star count
   - description
   - last commit date shown
   Do NOT click any repo links. Do NOT paginate. Return JSON array of objects with fields: repo, stars, description, last_commit." \
  --sync > /tmp/oss_github.json &

# Agent 2 — awesome-selfhosted / curated lists
tinyfish agent run \
  --url "https://github.com/awesome-selfhosted/awesome-selfhosted" \
  "You are on the awesome-selfhosted README page. Search this page for any tools related to '{TOOL_USE_CASE}' or '{TOOL_NAME}'.
   List up to 5 matching entries with their name, one-line description, and the GitHub URL if shown.
   Do NOT follow any links. Do NOT scroll more than twice. Return JSON array with fields: name, description, url." \
  --sync > /tmp/oss_awesome.json &

# Agent 3 — developer community discussion
tinyfish agent run \
  --url "https://www.reddit.com/search/?q=open+source+alternative+{TOOL_NAME}+self+host&sort=relevance&t=year" \
  "You are on Reddit search results for open source alternatives to {TOOL_NAME}.
   Read the titles and snippets of the top 8 posts. Extract any specific tool names mentioned as alternatives.
   Do NOT click any post links. Do NOT scroll. Return a JSON array of tool names mentioned: [{name, context}]." \
  --sync > /tmp/oss_reddit.json \
  --browser-profile stealth &
