What developers are struggling with, and what to build

Social platform posting APIs (X, TikTok, Meta, LinkedIn) fail at agent-driven publishing due to paywalls, audit restrictions, and silent permission failures, forcing a four-month custom integration build.

“Meta: your app admin gets Page access your users don't, and it fails silently — they see a successful connect, then an empty list.”

Current workaround

Built PostSider, an open-source AGPL-3.0 self-hosted layer with 33 connectors, approval gating, idempotency keys, and HMAC-signed webhooks.

Persistent agent sandboxes fail to pick up changed env vars or egress allowlist entries without a restart, and stuck npm installs behind a proxy fail silently instead of loudly.

“a persistent sandbox that does not pick up changed env vars or allowlist entries without a restart bit me more than once. Third, a wall-clock timebox per run, because a stuck npm install behind a proxy fails silently rather than loudly.”

Current workaround

Runs a daily job that clones and runs fresh open-source projects in a sandbox with an egress allowlist and a proxy for package registries, plus a wall-clock timebox per run.

Claude's review agent, run against end output, hunted bugs and rewrote core functionality twice, burning a week and tokens on fixes.

“claude rewrote a core functionality twice, wasted a week and tokens on just fixing it.”

Current workaround

Built sonah.dev to review agent sessions and highlight the decisions the agent made along the way.

PostgreSQL fails at ingesting multi-TB SCADA time-series (758 series, 13M rows per asset) causing instance growth from 8GB to 16GB and storage cooldown, with years-long range scans risking five-figure annual costs.

“I rebuilt it event-driven (Pub/Sub, Cloud Run, Terraform, Postgres) and — more usefully — gave it freshness SLOs and validation checks, so a silent failure goes from "someone notices missing data weeks later" to an alert in seconds.”

Current workaround

Designing a warm/cold split: Parquet on GCS for cold storage, partitioned + BRIN-indexed Postgres for the hot window, plus a coverage catalog table in Postgres mapping series/range to partition and object.

Apple Developer Program enrollment web payment flow silently fails to save cards and declines payments across browsers, causing multi-year enrollment dead-ends.

“The web "Payment & Shipping" page silently fails to save cards for a lot of people (long spinner, then nothing, no error).”

Current workaround

Add card via iPhone/iPad Apple Account first, retry in Safari, request per-region phone callback to manually complete the order.

Flat in-memory NumPy cosine similarity over ~1,500 chunk embeddings works instantly but the author lacks guidance on the order of magnitude where it breaks down before needing sqlite-vec/pgvector/ANN.

“For those who have pushed flat in-memory search further: at what order of magnitude (15k? 50k?) does this genuinely fall over before it makes sense to bring in something like `sqlite-vec`, `pgvector`, or an ANN index?”

Current workaround

Bare-metal flat NumPy cosine similarity across ~1,500 chunk embeddings held in memory (<2ms), avoiding a dedicated vector DB.

Node.js V8 and Java JDI/JVMTI fail to expose call-stack variables beyond the last async boundary or current frame, forcing engineers to manually scatter probes to debug silent logic bugs.

“nodejs only gives it only till the lasy async boundary, after that v8 itself drops this data. java only gives you the current frame, to get variables beyond that you would needs JDI/JVMTI which would block your threads, usually unnacceptable in production”

Current workaround

Add multiple probes across the call chain and collate collected data using the traceId from the context (or thread id as a fallback).

Cron-based scheduled jobs report success (exit code 0) while silently producing empty files, partial data syncs, or incomplete reports, causing undetected data integrity failures.

“I'm not going through log files every day to see if something silently failed.”

Current workaround

Built a simple monitoring tool that watches job results (file size, count, etc.) instead of just execution and alerts when results are off.

Heroic game launcher on Linux fails at running Epic games via Proton, causing broken cutscenes, misplaced save files after updates, and silent launch failures, forcing manual version hunting.

“Nb this all comes with a big asterisk, as you're very much into non-console-like operation with any of this—I had to intervene with Heroic's installation of The Outer Worlds (from Epic) once to get it running with functioning cutscenes, which took me probably 30 minutes including a lot of trawling Reddit and forums to…”

Current workaround

Manually trawled Reddit/forums to find a working Proton version and intervened in Heroic's install to fix cutscenes and locate misplaced saves.

VSCode's SSH remote plugin fails to reuse sessions and skips MotD, causing dozens of stale sessions accumulating over months that admins must manually clean up.

Wrote a custom script to boot/kill stale user sessions.

WordPress plugin lifecycle (install then uninstall of a translation plugin) leaves defaced/corrupted page content, forcing manual remediation across all translatable text.

“Just today I spent three hours to manually fix a page where a customers site was defaced after they installed and then uninstalled a translation plugin. I had to write a script that manually check every single instance of translatable text there is on the website.”

Current workaround

Wrote a custom script that manually checks every instance of translatable text on the website.

Resident LoRA training of 8B models fails with CUDA OOM on 4GB laptop GPUs, forcing users to work around the frozen-base VRAM constraint.

“Also Qwen2.5-3B with an un-quantized bf16 base at 143 tok/s in 2.15 GB, which is CUDA OOM when trained resident on the same card.”

Current workaround

Streams frozen base weights from host RAM into pre-allocated VRAM buffers one decoder layer at a time, prefetched one ahead on a dedicated CUDA stream.

Claude Code fails to associate chat sessions with git commits, forcing developers to manually trace which AI session produced an old commit.

“Back in the early days of claude code I had to write a script (well, claude wrote it) to pull out the session id and append it to every commit. It's a lifesaver when you are trying to debug an old commit to pull up the chat session that actually wrote it.”

Current workaround

GitHub Actions event payload expressions silently null-coalesce to '' on branch pushes, causing CI conditions that work on PRs to silently skip or fail on develop/main.

“Nullable event payloads silently null-coalescing to '' are a real "spooky action at a distance" kind of issue, because something that works perfectly when running and being QA'd on PRs, can silently fall apart if made to also run on the main/develop branch”

Current workaround

Inline comments documenting the contains('') behavior and explicit if: conditions guarding against missing pull_request payloads.

OpenAI Codex's logging writes unbounded WAL data to local SSDs, exhausting disk space and locking up the server.

“I've been bitten by this bug for several days, to the point where I had had to write a script to delete the WAL so that my server would stop getting locked up from a lack of disk space from codex logging.”

Current workaround

Custom script that deletes the WAL to prevent disk exhaustion and server lockups.

PostgreSQL cannot isolate high-volume query connections to a limited set of CPU cores, causing grid workloads to saturate the server.

“I wish there was a way for postgresql to isolate those connections to a limited set of cores (or number of cores). To avoid completely saturating the server.”

Immich's import pipeline (via immich-go or iOS app) silently corrupts photos, causing ffmpeg to fail metadata extraction with no UI error, only visible in logs.

“I have some 9000 photos which it silently fails to extract metadata from. The only sign in the UI that something is off is the fact those 9k photos never get processed, you can try in perpetuity.”

Current workaround

Manually inspecting logs to discover failed photos and using external immich-go tool checked out from GitHub for import.

Airtable's API fails to expose automations, interfaces, and webhooks, and its schema has ambiguous field types, causing migration edge cases to surface late during Postgres moves.

“Every time I thought I had the schema mapped, something new showed up. A lookup field behaving like a rollup. A linked record set up as single-link but actually used many-to-many.”

Current workaround
