No official list of “all” AI agents exists — 64 open-source projects clear a 10k-star, two-host popularity bar

Asked:

“List ALL popular open-source agents and agentic frameworks”

There is no authoritative universe of “all popular” agents, so this report uses an operational rule: projects reported at 10,000+ GitHub stars in a live-web scan and independently mentioned on at least two web hosts. From 3,315 extracted project mentions, 64 projects qualified — 39 agentic frameworks / SDKs and 25 open-source agent applications. Star figures are approximate snapshots from pages published on different dates, not live GitHub counts.

Agentic framework / SDK Open-source agent application likely alias / renamed continuation of another row

OpenClaw leads at ~380k reported stars — more than 1.7× the next non-alias project, opencode (~203k). glukhov.org

LangChain is the most independently corroborated project: 48 mentions across 31 distinct hosts, more than any other row. fungies.io

Frameworks / SDKs outnumber end-user agent applications 39 to 25, but four of the top six projects by stars are applications. the-agent-report.com

Eight rows are flagged as likely aliases or renamed continuations — Hermes Agent, Codex variants and OpenHands each appear under multiple names because source URLs differed. pinggy.io

Inclusion rule and exclusions. Included: projects reported at 10,000+ GitHub stars and mentioned on at least two independent web hosts, after semantic relevance filtering and name normalization of 3,315 extracted mentions. Excluded: models, datasets, tutorials, prompt/skill collections, generic chat UIs, MCP directories, benchmarks, observability-only tools, and unrelated infrastructure. “Open source” here reflects source descriptions and repository availability in a broad scan; license-level due diligence is still needed before commercial adoption. Rows highlighted in yellow are likely aliases or renamed continuations of another row (notably Hermes Agent, Codex/Codex CLI, and OpenHands) kept because their source names and URLs differed.

Method: 64 normalized open-source agent and agentic-framework projects screened from 3,315 project mentions across ranked lists, directories, comparisons, GitHub lists and coverage pages on the live web (2026 snapshots). “Stars ≈” is the representative reported GitHub star count from source pages published at different dates, not a live count; each row also carries its mention count and number of independent source hosts. Inclusion: ≥10,000 reported stars on ≥2 hosts. Long purpose text trimmed for space; full focus shown in the table.
