Plain is a full-stack Python web framework explicitly designed to work well with both human developers and AI agents. A fork of Django driven by ongoing development at PullApprove, it reimagines proven patterns for the agentic era: explicit, typed, predictable code that LLMs can understand, navigate, and modify without disambiguation. The framework ships with built-in agent tooling including rules files in '.claude/rules/' for guardrails and installable agent skills like '/plain-install', '/plain-upgrade', and '/plain-optimize'. The CLI unifies development into four commands: 'plain dev', 'plain fix', 'plain check', and 'plain test'. Thirty first-party packages cover authentication, analytics, payments, and more — reducing the assembly burden of a typical Django project. The tech stack is deliberately modern: PostgreSQL ORM with QuerySet API, Jinja2 templates, htmx and Tailwind CSS for frontend, Astral tools (uv, ruff, ty) for Python tooling, and oxc/esbuild for JavaScript. Python 3.13+ required. The design philosophy — prioritizing clarity and structure specifically to make code comprehensible to LLMs — reflects a bet that agentic-native frameworks will outperform retrofitted ones as AI-assisted development becomes the norm.

Remoroo
AI agent that remembers every run — built for long-running research and optimization loops

Remoroo is an AI agent purpose-built for long-running autoresearch and optimization workflows. The core loop is simple: give it a codebase and a measurable target, and it iterates autonomously — patch → run → eval → repeat — while maintaining a persistent memory of every attempt. It directly attacks the most frustrating failure mode in agentic coding: the agent that forgets what it already tried and circles back to dead ends hours into a job. The memory architecture stores code style preferences, project context, experimental hypotheses, and outcome measurements across sessions. When an agent run is interrupted or the job takes multiple days, Remoroo picks up with full context rather than starting from scratch. This is particularly valuable for ML training optimization, benchmark improvement tasks, and code performance tuning where individual runs take hours and the value is in the accumulated learning across dozens of attempts. Remoroo surfaced on Hacker News and the Hugging Face forums with strong interest from ML researchers and engineers who've been struggling with the same problem in their own workflows. It's early-stage, but it addresses a gap that every team running long-horizon AI agents has hit.
Reviewer scorecard
“A Django fork that actually makes the right tradeoffs for 2026: drops the legacy baggage, goes all-in on PostgreSQL and type annotations, and adds first-class agent tooling with Claude rules files and installable agent skills. The unified CLI ('plain dev', 'plain fix', 'plain check', 'plain test') is the kind of opinionated ergonomics that makes day-to-day development faster. If you're starting a new Python web project and want it to work well with Claude Code, Plain is worth evaluating seriously.”
“The patch-run-eval-repeat loop with persistent memory is exactly what's missing from existing coding agents. I've wasted days watching agents revisit approaches they already tried because they lost context. Remoroo's memory-as-infrastructure approach is the right abstraction. Would ship for any multi-day optimization task today.”
“Django has survived 20 years because its stability and ecosystem matter more than its legacy baggage. Plain has 30 first-party packages and one production deployment: PullApprove, the startup that built it. That's not a community, that's a well-maintained internal framework that got open-sourced. 'Designed for agents' is also a questionable differentiator — Django apps work fine with Claude Code because LLMs read Python, not because the framework has agent-native features. The rules files in .claude/rules/ are just advisory text, same as CLAUDE.md.”
“Very early — the website is sparse and there's no published information about the memory architecture, storage backend, or how context degradation is handled over hundreds of runs. The HN discussion is promising but the product itself is pre-documentation. Check back in three months.”
“The design philosophy — explicit, typed, predictable code that machines can understand and modify — points to a real insight: the frameworks we write code in will increasingly be co-designed with AI agents as first-class users. Plain is early proof that 'agentic-native' is a legitimate axis for framework design, not just a marketing adjective. Expect other frameworks to adopt similar agent tooling within two years.”
“Persistent, searchable agent memory across sessions is one of the fundamental missing pieces for agents that operate at human research timescales. Remoroo's focus on measurable targets and outcome-based memory makes it more rigorous than naive conversation logging. This points toward agents that genuinely compound knowledge over weeks and months.”
“For indie hackers building SaaS products with AI assistance, a framework built to be understandable by both you and your coding agent reduces the friction of the 'explain this codebase to Claude' step. The 30 first-party packages covering auth to analytics mean you're not assembling Django plugins from six different maintainers.”
“Interesting for technical research workflows but the use case is narrow — it's optimizing code and ML runs, not creative or design work. The tool needs to demonstrate how it generalizes beyond quantitative optimization before it's compelling for broader creative applications.”
