Fiberplane

What Fiberplane does

Fiberplane is an Amsterdam-based private software company founded in 2021 that builds developer and SRE tooling positioned around AI-assisted software development workflows. Originally launched with collaborative notebooks for site reliability engineers to coordinate incident response, the company has publicly repositioned itself as an "agent lab" building tools for the "Software Factory of tomorrow," functioning as a control plane for software work in the age of AI agents. Its portfolio comprises three products: FP, a local-first, agent-native issue tracking system built for Claude Code and distributed via fp.dev; EV, an AI-powered code review tool that turns code diffs into narrative stories from terminal or desktop (status: Coming soon); and DRIFT, an open-source documentation drift detection tool that binds specifications to code and warns before stale documentation reaches main, available on GitHub as fiberplane/drift.

Underlying the product line is a local-first, agent-native architecture designed for AI-augmented development sessions, with tight integration to Claude Code and GitHub. The company employs 11-50 people, is led by founder and CEO Micha Leuffen, and operates a product-led growth (PLG) go-to-market: products are distributed via fp.dev and GitHub, with community engagement through an active Discord channel and content marketing via a company blog. Pricing is not publicly disclosed, and no paying customers or enterprise logos are documented in the available sources. Its stated customer segments are horizontal, targeting SREs for incident coordination and broader software developers for AI-assisted issue tracking, code review, and documentation integrity.

Commercially, Fiberplane has raised a single disclosed seed round of €7.5 million in September 2021, co-led by Crane Venture Partners and Notion Capital with participation from basecase capital, Northzone, and System.One. The revenue model is inferred to be subscription/recurring based on PLG software distribution norms, but specific pricing tiers, ARR, and customer counts are not disclosed. The company remains private and operates from its Amsterdam headquarters.

Core offering

Fiberplane builds and sells an agent-native software development toolkit centered on three products: FP (local-first, agent-native issue tracking integrated with Claude Code), EV (an AI-powered code review tool that turns code diffs into narrative stories), and DRIFT (a documentation drift detector that binds specifications to code). The products are targeted at software engineers, developers, and site reliability engineering (SRE) teams, and are distributed directly via fp.dev, GitHub, and a Discord community. The company originally focused on collaborative notebooks for SRE incident response and has expanded into a broader operational platform for AI-assisted development workflows.

Product overview

Fiberplane is an agent lab building tools for the Software Factory of tomorrow, serving as the control plane for software work in the age of agents. The company offers a portfolio of three products: FP (local-first, agent-native issue tracking built for Claude Code), EV (AI-powered code review tool that generates narratives from diffs), and DRIFT (documentation drift detection that binds specs to code). The product suite is designed for AI-augmented development workflows.

Differentiator

Problem solved

Functional benefit

Products and services

• FP FP is Fiberplane's local-first, agent-native issue tracking system built for use with Claude Code and focused, AI-assisted development sessions. It targets software engineers and developer teams who want issue tracking tightly coupled with their AI coding agent workflow rather than a separate cloud-hosted tracker. The product is distributed directly via fp.dev.
• DRIFT DRIFT is an open-source documentation drift detection tool that binds specifications to code, lints the codebase for drift between code and docs, and warns developers before stale documentation reaches the main branch. It is targeted at software engineers and developer teams that maintain living specifications alongside their code, and is distributed as an open-source project on GitHub.

Direct peers

• Cursor: AI-powered code editor and development environment that serves as a primary AI-assisted coding tool for software engineers. Direct competitor to Fiberplane in the agent-native developer tooling space, though focused on the editing layer rather than issue tracking or code review.
• Linear: Issue tracking and project management tool widely used by software engineering teams. Direct competitor to Fiberplane's FP product in the developer-focused issue tracking category, particularly relevant given Linear's PLG motion and developer mindshare.
• Rootly: Collaborative incident response and on-call management platform for SRE teams. Direct competitor to Fiberplane's original SRE-focused collaborative notebook offering, and a useful comparison for the heritage product line.
• Incident.io: Incident management platform built for Slack and modern engineering teams, focused on SRE incident response workflows. Direct peer in Fiberplane's original SRE collaborative tooling category.
• Firehydrant: Incident response and SRE workflow platform that helps engineering teams manage on-call, incident response, and post-mortems. Direct peer to Fiberplane's original SRE notebook positioning.

Broad incumbents

• GitHub Copilot: Microsoft-owned AI coding assistant integrated across the GitHub platform, including code completion, chat, and increasingly agent-based workflows. Broad incumbent in AI dev tools with substantially greater distribution and resources than Fiberplane.
• Snyk: Developer security platform focused on identifying vulnerabilities in code, dependencies, and infrastructure. Broad incumbent with overlap to Fiberplane's DRIFT product (which prevents stale/insecure documentation from reaching production) in the code quality and supply chain tooling category.

Emerging players

• Sourcery: AI-powered code review tool that automatically reviews pull requests and suggests improvements. Direct emerging competitor to Fiberplane's EV product in the AI code review category.
• Continue: Open-source AI code assistant that integrates with IDEs and supports multiple model providers. Emerging player in agentic coding workflows with similar open-source developer-led go-to-market approach as Fiberplane's DRIFT.
• Aider: AI pair programming tool that operates in the terminal and works with multiple LLMs for code generation and editing. Emerging open-source peer in the AI-assisted development workflow space where Fiberplane is positioning its product suite.
