GitHub trending repositories: August 20 2026

modular/modular leads GitHub Trending Repos on August 20, 2026, after the August 11 release of MAX 26.5 and Mojo 1.0. Every repository on the 17-item Trends MCP board is new compared with the August 14 report, producing a complete turnover rather than a few isolated movers. Developer skills, agent memory, context databases, and AI security tools account for most ranks, while RyanCodrai/turbovec enters at rank 17 two days after its 1.0.0 package release.

All 17 repositories are published because the August 20 source returned 17 items, led by a programming-language milestone and a concentrated group of agent-development projects.

  1. modular/modular: Modular's repository contains Mojo, MAX, and accelerator libraries. MAX 26.5 and Mojo 1.0 shipped on August 11, followed by a ModCon event on August 18.

  2. mattpocock/skills: Matt Pocock's collection packages engineering workflows for planning, debugging, testing, and domain modeling as agent skills. No widely reported trigger identified for August 20, 2026.

  3. AprilNEA/OpenLogi: OpenLogi is a local-first Rust alternative to Logitech Options+ for button mapping, DPI, and SmartShift controls. Version 0.7.1 shipped on August 15 with device, certificate, and release fixes.

  4. obra/superpowers: Superpowers is a composable skills framework and software-development method for coding agents. Version 6.3.0 shipped on August 12, but no separate August 20 trigger was identified.

  5. cursor/plugins: Cursor's official plugin specification and marketplace repository contains integrations for developer tools and services. Interest follows the August rollout of the Agent Plugins 1.0 working draft and portable plugin support.

  6. santifer/career-ops: Career Ops turns AI coding command-line tools into a local job-search pipeline for evaluating listings, tailoring CVs, and tracking applications. No widely reported trigger identified for August 20, 2026.

  7. akitaonrails/ai-memory: This Rust MCP server stores long-term coding-agent memory and supports handoffs among several agent products. No widely reported trigger identified for August 20, 2026.

  8. harry0703/MoneyPrinterTurbo: MoneyPrinterTurbo automates short-video scripts, stock footage, voiceovers, subtitles, and final video assembly. A project release landed on August 12, with no separate August 20 trigger identified.

  9. agent-substrate/substrate: Agent Substrate is a Kubernetes-native runtime that snapshots idle agents and restores them inside isolated sandboxes. No widely reported trigger identified for August 20, 2026.

  10. chaitanyagiri/munder-difflin: Munder Difflin coordinates teams of coding agents through a desktop command center with memory, messaging, and scheduling. Version 0.4.4 shipped on August 18 with Windows messaging and setup fixes.

  11. PostHog/posthog: PostHog is an open-source product analytics and developer tooling platform. Desktop version 0.60.271 shipped on August 19 with task filters and faster cloud transcript loading.

  12. mahlernim/google-timeline-visualizer: This Android tool turns exported Google Maps Timeline data into animated travel videos. No widely reported trigger identified for August 20, 2026.

  13. volcengine/OpenViking: OpenViking is a context database that stores agent memories, resources, and skills in a virtual filesystem. Reporting on August 19 highlighted 29,000 GitHub stars and 213 added in one day.

  14. JuliusBrussee/caveman: Caveman compresses agent output and input data to reduce token use. Version 2.0.0 added its input-compression engine on August 11, followed by later 2.x updates.

  15. makeplane/plane: Plane is an open-source project and product-management system. Its latest identified stable release, version 1.4.1, shipped on August 7; no fresh August 20 trigger was identified.

  16. Tencent/AI-Infra-Guard: Tencent's AI security scanner tests agents, MCP servers, skills, and model infrastructure. Version 4.5.2 shipped on August 17 with bytecode bypass detection, charset-smuggling defenses, and new SkillJack research.

  17. RyanCodrai/turbovec: Turbovec is a Rust vector index with Python bindings built on the TurboQuant algorithm. Version 1.0.0 reached PyPI on August 18 with SIMD search kernels for ARM and x86.

What changed on GitHub since August 14

The entire 17-repository board changed between the August 14 and August 20 reports, leaving no returning project and therefore no rank-to-rank mover.

ChangeDetails
New entriesAll 17 repositories, led by modular/modular (#1), mattpocock/skills (#2), and OpenLogi (#3)
Returning entriesNone
Big moversNone, because no August 14 repository returned
Drop-offsAll 17 prior entries, including diagram-design (#1), semantica (#2), anthropics/skills (#3), and needle (#4)

The reset removes the August 14 leaders along with macro, FluidVoice, unsloth, holehe, spiderfoot, Switchyard, holaOS, obsidian-skills, manim, agency-agents, LTX-2, modly, and ragflow. That scale of turnover makes category composition more useful than direct rank movement.

Agent development dominates the board. At least 11 of the 17 repositories address agent skills, memory, context, orchestration, infrastructure, security, or supporting vector search, with mattpocock/skills at rank 2 and Tencent/AI-Infra-Guard at rank 16 marking the range.

Dated releases explain several placements. Mojo 1.0 shipped August 11 before modular/modular reached rank 1, Munder Difflin 0.4.4 landed August 18 before rank 10, PostHog's desktop update arrived August 19 before rank 11, and turbovec 1.0.0 reached PyPI August 18 before rank 17. Projects without a reported same-day event are labeled accordingly rather than assigned an inferred cause.

These 17 ranks came from the Trends MCP API on August 20, 2026, using type GitHub Trending Repos and limit 50. The feed records daily repository order for developer research. The GitHub Trending Repos API page documents the source.
