Pains

OpenAI API unexpectedly auto-generates questions and answers during calls, producing output that wasn't requested and requiring developers to implement additional filtering logic.

Railway lacks native Android and iOS apps, creating a gap in the mobile-first developer workflow. As AI-powered coding tools (e.g., Cursor, Copilot) enable mobile development, Railway cannot support the end-to-end mobile deployment lifecycle.

New Go developers struggle with understanding type assertions and conversions, leading to unexpected behavior especially with maps and slices. Poor type system documentation exacerbates the problem.

GitHub Actions workflows generated between 150.5 and 994.9 million tons of CO₂ equivalent in 2024, creating a significant environmental concern for companies mindful of their carbon footprint.

Railway does not provide project migration functionality, making it difficult to reorganize or consolidate projects without manual workarounds.

FastAPI applications consume more resources compared to lighter frameworks like Flask, Bottle, and Falcon, which can be problematic for projects with strict resource allocation restrictions.

Railway's interface and abstraction model are developer-centric, making it difficult for non-technical team members to navigate templates, integrations, and configuration without deep technical knowledge.

FastAPI has a younger ecosystem compared to established frameworks like Django and Flask, resulting in fewer third-party extensions and less community-contributed solutions. Users must often build missing features themselves.

Due to its novelty, FastAPI lacks extensive adoption in large-scale projects, making long-term scalability and operational reliability less certain. Few large-scale case studies limit available guidance for enterprise applications.

CSS has a confusing, scattered API with inconsistent naming conventions across properties and rules, making it difficult to remember and predict behavior.

GPT-5 can feel slower than GPT-4o for simpler, everyday queries and coding tasks. Community backlash occurred regarding performance degradation for simple coding tasks before OpenAI fine-tuned model routing.

Unlike Django, FastAPI has no built-in admin interface. Teams must build dashboards manually or integrate third-party tools, significantly slowing down development for CRUD-heavy applications and internal tools.

TypeScript's standard library type definitions have not kept pace with JavaScript's TC39 proposals. Temporal began shipping in JavaScript engines but TypeScript issue #60164 shows the type definitions are still missing, creating a gap between runtime capabilities and type safety.

The 100vh unit does not account for mobile browser chrome (address bar, nav bars), causing layout overflow and poor mobile UX.

Developers neglect to properly configure .gitignore files, causing compiled binaries, log files, and temporary files to be tracked in version control. This clutters repositories, confuses collaborators, and bloats repository size unnecessarily.

Custom plugins and database integrations are not supported and will take considerable time to implement. The team acknowledges this is a complex undertaking (Figma took six years) with no clear timeline for Railway.

Docker tutorials and documentation either assume users are power users with deep knowledge or are so trivial that they don't represent real-world solutions, making them essentially useless for practical development scenarios.

Developers must preprocess or segment large or structurally complex texts to meet API constraints while preserving information integrity, adding complexity to implementations.

Developers commonly hard-code S3 locations in application code, tying code to deployment details. This breaks multi-environment setups, data migrations, and code auditing efforts.

Developers working with the Audio API encounter task-specific challenges related to audio format conversion, requiring specialized handling for different audio formats.

Developers fail to implement Git hooks, missing opportunities for automation. Without hooks, developers must manually remember to run various checks or commands, increasing the risk of errors and reducing workflow efficiency.

FastAPI's DI system doesn't natively support singletons, forcing teams to manually manage shared resources through singleton classes or adopt third-party DI libraries.

MSAL.js applications commonly encounter redirect loops when loginRedirect is automatically triggered on page load without first verifying user sign-in status. Developers must manually implement account state checks before triggering authentication, adding boilerplate code to prevent loops.

The three animation composition modes (`replace`, `add`, `accumulate`) produce subtly different results that are easy to misunderstand, leading to unexpected animation behavior and debugging difficulty.
