Runtime
Pros
- + Build workflow proves agents on seeded cases with read-only credentials before guardrails exist, then derives command allowlists and approval gates from what passing runs actually did
- + Every run records the prompt, tool calls, token and compute cost, result and grade separately — an audit file I could show to a compliance reviewer, not a summary
- + Deployable inside your own VPC with bring-your-own sandbox support (Firecracker, gVisor or custom VM infrastructure), so payment data never leaves your network
- + Scorecard aggregates grades and monthly spend per agent and includes a 'what a human would have spent' baseline, which makes cost-per-outcome conversations with finance concrete
- + Trigger surface is broad and operational: Slack, Linear, GitHub, email, WhatsApp, SMS, cron and API, with results posted back to the originating channel
Cons
- - No public pricing anywhere on the site — every path ends at 'Book a demo', so there is no self-serve entry and no way to model cost before engaging sales
- - Very young company (Y Combinator's 2026 batch) with one named customer case study and no independent review history to cross-check vendor claims
- - Purpose-built for payment, risk and compliance work; teams doing general knowledge work will find most of the machinery has nothing to operate on
- - Onboarding assumes engineering comfort: templates carry MCP servers, secrets and repositories that someone technical has to configure
- - Headline savings figures on the homepage are marked illustrative by Runtime's own footnote, so they should not be read as measured benchmarks
Browserbase
Pros
- + Session replay, live viewing and logs turned a failing agent step into a diagnosable one — the debugging surface is the strongest I have used in this category
- + Attaching Playwright over CDP behaved like a local browser in my runs: real rendering, cookie persistence across requests
- + Stagehand (MIT, 25k+ stars) lets agents mix natural-language actions with ordinary Playwright code, and runs locally for free before you need hosted scale
- + Itemized public pricing with a real free tier to prototype on, including $5 in model tokens and 1,000 search/fetch calls
- + Identity features (auto captcha solving from Developer tier, Verified Sessions on Scale) address the part of browser automation that actually fails in production
Cons
- - Six separately metered line items — hours, proxy GB, search, fetch, agent runs, model tokens — so the plan price is a floor, not the bill
- - Proxy sessions carry a 1 MB minimum per session; high-volume tiny sessions pay for data they never moved (~$120 per 10,000 sessions at Developer proxy rates)
- - Stealth tiering is underspecified: public docs never define what 'Basic' excludes versus Advanced/Verified on Scale
- - Free tier is a demo — 1 browser hour/month and 15-minute session caps stopped my first long test exactly at the limit
- - No local-only or self-hosted option for the hosted stack; latency variance versus local browsers is inherent to the model
