Six stacks we keep current. Not a roundup of everything that exists — the tools we run every week, in the order we reach for them, with the ones we passed on and why.

The newsletter stack.
For one person writing weekly to ~20k readers. Built for speed, not scale.
01Beehiiv — host + segmentsdaily
02Claude Sonnet 5 — drafts + editsdaily
03Notion — ideas vaultweekly
04Granola — interview notesweekly
05Stripe Atlas links — monetizemonthly
Why these picks
010% take rate vs Substack's 10%. Ad network + Boosts pay for the subscription most weeks.
02Better tone matching than GPT-5.6. Longer instruction adherence than Gemini 3.
03Database queries no one else does as well. Free tier is enough for a one-person shop.
04Local-first transcription — audio never leaves the laptop. Doesn't feel like a SaaS demo.
05Direct Stripe Payment Links in the footer. No platform fee, no upsell flow. Covers hosting most months.
We'd switch if…
Beehiiv raised Scale past $75/mo — evaluate Buttondown ($29/mo) or Kit ($89/mo).
Sonnet loses the tone edge to Gemini 3 or GPT-5.6. Opus 5 is the upgrade path when a draft has to land first time.
Notion kept adding AI features we don't want. Obsidian is the likely replacement.
Granola changed the local-first model.
What we tried and dropped
Substack — 10% take rate, social feed pollution, discovery engine wants your readers more than you do.
ConvertKit / Kit — fine product, pricing scales faster than Beehiiv at our band.
Mailchimp — not even close.
Ghost — beautiful, but the CMS-first design adds friction we don't need.
agents · long-running workflowsre-ranked · aug '26
The agent stack.
For the agents we let run unattended overnight. The ones that pay.
01Anthropic API — Sonnet 5 + tool usedaily
02Inngest — durable queuesdaily
03Browserbase + Playwrightdaily
04Supabase Edge Functionsweekly
05Langfuse — traces & costdaily
Why these picks
011M context at standard pricing. Tool use that doesn't hallucinate arguments. Best instruction-following for multi-step work.
02Durable steps that retry from where they failed with cached outputs. Replaces a queue + state machine + cron.
03Managed Chromium with stealth (FingerprintJS >80% human). Plain Playwright is the boring answer that doesn't break.
04Postgres + auth + storage + edge in one place at $25/mo. Cold-starts in 200–500ms.
05Every step traced — tokens in/out, cost, latency, the prompt. Without this you have no idea why an agent burned $40 overnight.
We'd switch if…
Anthropic raised Sonnet past $5/$20. GPT-5.6 is close on price but tool use is noisier. Opus 5 landed at half of Fable 5, so the ceiling got cheaper too.
Inngest lost durable-step semantics. Trigger.dev is cheaper at entry but less mature.
Browserbase raised prices materially. Bug0 Browsers ($0.15/hr) is the credible alternative.
Supabase kept pushing self-hosted complexity. Neon is on the table for bursty workloads.
Langfuse changed unit-pricing math after the ClickHouse acquisition.
What we tried and dropped
LangChain / LangGraph — abstraction tax we didn't need. Anthropic SDK + Inngest does the same with fewer footguns.
AWS Step Functions — every line becomes IaC. Fine for big orgs, terrible for shipping.
Temporal — over-engineered for what we do. Inngest is what Temporal would be if it shipped this decade for normal teams.
CrewAI / AutoGen — multi-agent frameworks that solve a problem we don't have.
